<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Duos Technologies Group, Inc. (the &#8220;Company&#8221;),
through its operating subsidiaries, Duos Technologies, Inc. and TrueVue360, Inc. (collectively the &#8220;Company&#8221;), develops and
deploys vision based analytical technology solutions that will help to transform precision railroading, logistics and inter-modal transportation
operations. Additionally, these unique patented solutions can be employed into many other industries.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#8220;AI&#8221;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has built a portfolio of IP and patented
solutions that creates &#8220;actionable intelligence&#8221; using two core native platforms called Centraco&#174; and Praesidium&#8482;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#8482; with the objective of focusing the Company&#8217;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions. The Company also offers
technical support services for the above products.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also provided professional and consulting
services for large data centers and had developed a system for the automation of asset information marketed as DcVue&#8482;. The Company
had deployed its DcVue software at one beta site. This software was used by Duos&#8217; consulting auditing teams. DcVue was based upon
the Company&#8217;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed
software product. The Company ceased offering this product in 2021.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s strategy is to deliver operational
and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics
and U.S. Government Sectors, offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and
improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based
work force where employees enjoy their work and are incentivized to excel and remain with the Company.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these
estimates. The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts
receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues
and the total estimated costs to determine progress towards contract completion, estimates of the valuation of right of use assets and
corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based awards. We base our estimates on
historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual
results may differ from these estimates.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For revenues related to technology systems, the Company
recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete
projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue
to recognize.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Accordingly, the Company bases its technology systems
revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance does
not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="a_Hlk103255145"></span>Under this method, contract
revenues are recognized over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material,
direct labor, subcontract labor and other allocable direct costs. All un-allocable indirect costs and corporate general and administrative
costs are also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an
asset in &#8220;contract assets&#8221;. Any billings of customers more than recognized revenues are recorded as a liability in &#8220;contract
liabilities&#8221;. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.</p>

multiple performance obligations may include any of the above four sources. Training and maintenance on software products may occur after

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Each performance obligation is accounted for separately
when each has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each performance obligations is recognized using the applicable criteria under GAAP as discussed above for performance
obligations sold in single performance obligation arrangements. A delivered item or items that do not qualify as a separate unit of accounting
within the arrangement are combined with the other applicable undelivered items within the arrangement. The allocation of arrangement
consideration and the recognition of revenue is then determined for those combined deliverables as a single unit of accounting. The Company
sells its various services and software and hardware products at established prices on a standalone basis which provides Company specific
objective evidence of selling price for purposes of performance obligations relative selling price allocation. The Company only sells
maintenance services or spare parts based on its established rates after it has completed a system integration project for a customer.
The customer is not required to purchase maintenance services. All elements in multiple performance obligations arrangements with Company
customers qualify as separate units of account for revenue recognition purposes.</p>

This guidance requires lessees to recognize right-of-use (&#8220;ROU&#8221;) assets and lease liabilities for most operating leases. In
addition, this guidance requires that lessors separate lease and non-lease components in a contract in accordance with the revenue guidance
in ASC 606.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company made an accounting policy election to
not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in expense
as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components as a single
lease component.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">At the inception of a contract the Company assesses
whether the contract is, or contains, a lease. The Company&#8217;s assessment is based on: (1) whether the contract involves the use of
a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout
the period, and (3) whether it has the right to direct the use of the asset.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Operating ROU assets represent the right to use the
leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over
the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based
on the information available at the lease commencement date to determine the present value of future payments. The lease term includes
all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not
to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included
in general and administrative expenses in the consolidated statements of operations.</p>

the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments
and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement
of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We adopted this pronouncement for
our fiscal year beginning January 1, 2022, and it did not have a material effect on our unaudited consolidated financial statements.</span></p>

the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a

In one previous financial report during 2021, the Company had raised substantial doubt about continuing as
a going concern. This was principally due to a lack of working capital prior to an underwritten common stock offering which was completed
during the first quarter of 2022 (the &#8220;2022 Offering&#8221;).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">During the previous 15 months, the Company has raised
more than $10 million after fees and expenses, both from existing shareholders through the issuance of Series C Convertible Preferred
Stock and in the first quarter of 2022, a follow-on common stock offering using its previously filed &#8220;shelf&#8221; registration.
Although, further additional investment is not assured, the Company is comfortable that it would be able to raise sufficient capital to
support expanded operations based on an anticipated increase in business activity. In the long run, the continuation of the Company as
a going concern is dependent upon the ability of the Company to continue executing the plan described above, generate enough revenue,
and eventually attain consistently profitable operations. Although the current global pandemic related to the coronavirus (COVID-19) has
affected our operations, particularly in supply chain, we now believe that this is expected to be an ongoing issue and our working capital
assumptions reflect this new reality. The Company cannot currently quantify the uncertainty related to the pandemic and its effects on
our customers in the coming quarters. We have analyzed our cash flow under &#8220;stress test&#8221; conditions and have determined that
we have sufficient liquid assets on hand to maintain operations for at least twelve months from the date of this report. A notable recent
success is the &#8220;bonding&#8221; secured in the amount of approximately $8 million for a major project for which the Company recently
received full &#8220;notice to proceed&#8221;.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company was successful in securing a loan of
$<span id="xdx_901_eus-gaap--SecuredDebt_c20220331_pp0p0" title="Secured loan"><ix:nonFraction name="us-gaap:SecuredDebt" contextRef="AsOf2022-03-31" format="ixt:numdotdecimal" decimals="0" scale="0" unitRef="USD">1,410,270</ix:nonFraction></span> during the second quarter of 2020
from the Small Business Administration via the PPP/CARES Act program which further bolstered the Company&#8217;s cash reserves. This
loan was forgiven in the first quarter of 2021 and leaves the Company essentially debt free other than the normal course of business
equipment and insurance financing. The Company has also been successful in increasing its working capital surplus after receiving
proceeds from the 2021 Offering of $4,500,000 and more recently, in the first quarter of 2022, receiving net proceeds of
approximately $<span id="xdx_905_eus-gaap--ProceedsFromOtherDebt_c20220101__20220331_pp0p0" title="Net proceeds bebt"><ix:nonFraction name="us-gaap:ProceedsFromOtherDebt" contextRef="From2022-01-01to2022-03-31" format="ixt:numdotdecimal" decimals="0" scale="0" unitRef="USD">5,500,000</ix:nonFraction></span>
from the successful sales of common stock under the Company&#8217;s &#8220;shelf registration&#8221; statement as previously
mentioned. This gives us the capital required to fund the fundamental business changes that we are executing including organization,
product alignment and market focus and maintenance of our business strategy overall. In addition, management has been taking and
continues to take actions including, but not limited to, elimination of certain costs that do not contribute to short term revenue,
and re-aligning both management and staffing with a focus on improving certain skill sets necessary to build growth and
profitability and focusing product strategy on opportunities that are likely to bear results in the relatively short term. During
2021, management took further significant actions including reorganizing our engineering and technical teams and selectively
improving organizational efficiency to effectively grow the business in concert with the influx of business won in late 2021 and
early 2022. Upon completion of the 2022 Offering, management has raised sufficient working capital to meet its needs for the next
12-months without the need to raise further capital. The Company had experienced a significant slowdown in closing new projects due
to cautious actions by current and potential clients as a result of COVID-19 but this appears to be abating as time passes. We
continue to be successful in identifying new business opportunities and are focused on maintaining a backlog of projects.</p>

in our market space with ongoing contract delays, the consequent need to procure certain materials in advance of a binding contract and
the additional time needed to execute on new contracts previously reported have put a strain on our cash reserves. However, recent events
including an approximate $5.5 million injection of funds from a sale of common stock, significant recent orders and the overall stabilization
of the business indicate that there is no longer substantial doubt for the Company to continue as a going concern for a period of twelve
months from the issuance of this report. We will continue executing the plan to grow our business and eventually achieve profitability
without the requirement to raise additional capital for existing operations for 2022 although we may do so to fund selective opportunities
that may arise. Management has extensively evaluated our requirements for the next 12 months and has determined that the Company currently
has sufficient cash to operate for at least that period.</p>

is the Company&#8217;s only lease with a term greater than twelve months. The office and warehouse lease has a remaining term of approximately
10.2 years and includes an option to extend for two renewal terms of five years each. The renewal options are not reasonably certain to
be exercised, and therefore, they are not included when determining the lease term used to establish the right-of use asset and lease
liability. The Company also has several short-term leases, primarily related to equipment. The Company made an accounting policy election
to not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in
expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components (such
as common area maintenance) as a single lease component.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b>Overview</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b>&#160;</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Duos Technologies Group, Inc. (the &#8220;Company&#8221;)
was incorporated in Florida on May 31, 1994 under the original name of Information Systems Associates, Inc. Initially, our business operations
consisted of consulting services for asset management of large corporate data centers and the development and licensing of information
technology (&#8220;IT&#8221;) asset management software. In late 2014, the Company entered negotiations with Duos Technologies, Inc. (&#8220;Duos&#8221;),
for the purposes of executing a reverse triangular merger. This transaction was completed on April 1, 2015, whereby Duos became a wholly
owned subsidiary of the Company. Duos was incorporated under the laws of Florida on November 30, 1990 for design, development and deployment
of proprietary technology applications and turn-key engineered systems. The Company, based in Jacksonville, Florida, has a current staff
of 66 people of which 58 are full time and is a technology and software applications company with a strong portfolio of intellectual property.
The Company&#8217;s core competencies, including advanced intelligent technologies, are delivered through its proprietary integrated enterprise
command and control platform, Centraco&#174;.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has developed the Railcar Inspection Portal
(&#8220;RIP&#8221;) which provides both freight and transit railroad customers and select government agencies the ability to conduct fully
remote railcar inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies,
illumination and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including
the undercarriage. These images are then processed through various methods of artificial intelligence algorithms to identify specific
defects and/or areas of interest on each railcar. This is all accomplished within seconds of a railcar passing through our portal. We
believe this solution has the potential to transform the railroad industry immediately increasing safety, improving efficiency and reducing
costs. The Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand from
transit and other railroad customers along with selected government agencies that operate and/or manage rail traffic in the future. Government
agencies can conduct digital inspections combined with the incorporated artificial intelligence (&#8220;AI&#8221;) to improve rail traffic
flow across borders which also directly benefits the Class 1 railroads through increasing their velocity.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has also developed the Automated Logistics
Information System (&#8220;ALIS&#8221;) which automates gatehouse operations where transport trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations, and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has built a portfolio of IP and patented
solutions that creates &#8220;actionable intelligence&#8221; using two core native platforms called Centraco&#174; and Praesidium&#8482;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also developed a proprietary Artificial
Intelligence software platform, Truevue360&#8482; with the objective of focusing the Company&#8217;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also provided professional and consulting
services for large data centers and had developed a system for the automation of asset information marketed as DcVue&#8482;. The Company
had deployed its DcVue software at one beta site. This software was used by Duos&#8217; consulting auditing teams. DcVue was based upon
the Company&#8217;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed
software product. The Company ceased offering this product in 2021.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">The Company&#8217;s strategy
is to deliver operational and technical excellence to our customers; expand our RIP and ALIS solutions into current and new customers
focused in the Rail, Logistics and U.S. Government Sectors; offer both CAPEX and OPEX pricing models to customers that increases recurring
revenue, grows backlog and improves profitability; responsibly grow the business both organically and through selective acquisitions;
and promote a performance-based work force where employees enjoy their work and are incentivized to excel and remain with the Company.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">The Company&#8217;s focus
is to improve operational and technical execution which, we believe, will in turn enable the commercial side of the business to expand
RIP and ALIS delivery into existing customers and to expand and diversify our current customer base. Even though COVID-19 is expected
to still be an issue during 2022, the Company&#8217;s primary customers have indicated readiness to order more equipment and services
should the Company execute as expected on key deliverables.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">Additionally, the Company
is making engineering and software upgrades to the RIP to meet anticipated Federal Railroad Association (FRA) and Association of American
Railroad (AAR) standards. Similar upgrades are also being developed to improve the ALIS system. These upgrades will continue to be released
throughout 2022 and are expected to drive revenue growth this year and beyond.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">The Company is expanding
its focus in the rail industry to encompass passenger transportation and was awarded a large, multi-year contract with a national rail
carrier. The Company anticipates that it will deliver at least two RIP solutions along with a long-term services agreement in 2022 and
completing delivery during the first quarter of 2023.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The decrease in overall revenues for the quarter
ended March 31, 2022 is primarily related to the timing of new installations in the technology systems portion of our business,
which was driven by delays in receiving anticipated &#8220;notices to proceed&#8221; for new contracts expected earlier in the year,
and supply chain issues which are extending deadlines for shipment of key components used in our technology systems. While certain
orders were delayed from 2021 into 2022, we remain encouraged by the breadth and scope of recent bids in which we have participated.
Management cautions that because of the delays in anticipated start dates, certain installations may produce revenues towards the
end of 2022, some of which may ultimately be recorded in 2023. Additionally, although the industries in which we operate are showing
early signs of recovery from the delays as a result of the COVID-19 pandemic, other macro-economic effects are anticipated to impact
us, including inflation and the current supply chain issues. The effect of this will be to push some revenue recognition later in
the year or into 2023. The effects of inflation are not quantifiable at the current time but are beginning to be evident in
increased costs for materials and labor. These effects may result in higher costs for project implementation that cannot be wholly
or even partially passed on to our customers and thus resulting in delaying our progress towards profitability.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">We believe the Company&#8217;s capital structure allows
us to weather the unexpected delays without significant operational impact and enables us to pursue large projects requiring the ability
to deploy major resources. It should be noted that the Company increased its working capital in late 2021 to account for an increase in
pre-contract procurement activities to avoid a slowdown in revenues caused by delays in receiving certain components. The Company undertook
a major review of operations during 2021 and made significant changes in staffing, including hiring additional engineering staff and revamping
its software development and Artificial Intelligence staffing. Although the Company implemented a &#8220;rapid development&#8221; initiative
in early 2021, which was intended to enable the Company to respond to market driven demand more quickly, this effort has been somewhat
negated by ongoing supply chain issues. This effort was expected to shorten delivery times on major projects and result in significant
revenue growth in the last six months of 2021 and beyond, the previously discussed supply chain issues have not allowed the anticipated
benefits to be realized at this time. The Company is monitoring the situation and had continued to procure materials ahead of formal contract
award late in the first quarter of 2022.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The services portion of revenues are driven by the
successful completion of projects and represent services and support for those installations. The Company expects growth with new revenue
from existing customers, including services revenue as the result of new maintenance contracts being established on installations coming
on-line during 2022. The Company also anticipates renewals of existing contracts and a shift to the next generation of technology systems
which are currently being installed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Cost of revenues largely comprises equipment, labor
and overhead necessary to support the implementation of new systems and support and maintenance of existing systems.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Cost of revenues on technology systems decreased during
the three months ended March 31, 2022 compared to the equivalent period in 2021, which is consistent with the decrease in revenues. However,
the percentage decrease in cost of revenues for technology systems for the current year period compared to the prior year period was lower
than the percentage decrease in revenues from technology systems for the current year period compared to the prior year period. The higher
level of cost compared to revenues was mainly due to higher costs of materials due to supply chain disruptions and inflation, as well
as additional work being necessary on certain of the Company&#8217;s installations to resolve newly identified quality issues. While we
expect that macro-economic factors will continue to drive prices, the Company expects its structural realignment to aid in lowering costs
as a percentage of the overall system price going forward. As previously noted, the Company&#8217;s organization and related cost structure
was realigned to provide the capability to manufacture, install and support multiple production systems simultaneously. In accordance
with this shift in structure, certain staff were re-assigned or replaced, and new staff added in key areas, particularly software engineering,
IT and AI.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In conjunction with these organizational changes,
increased costs are now being recognized against project and support revenues. While there is a continued focus on construction costs
and savings through efficiency, the Company has elected to expand its key employees in 2021 and early 2022 in anticipation of expected
sales growth in technology systems and services. These changes had a negative impact on the gross margin (see below) during the quarter
ended March 31, 2022, but this is expected to be a short-term impact, which we believe will be offset by anticipated increases in revenue
later in 2022. We also expect these changes to have a positive long-term impact as we believe they will enable the Company to deliver
a higher number of systems in a given period, with a shorter period of implementation and with better quality and reliability, as operations
become standardized in anticipation of expected higher demand for systems, particularly in the rail industry.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Cost of revenues on services and consulting decreased
in the three months ended March 31, 2022 compared to the prior year period in line with the decrease in revenues from services and consulting
for the current year period as compared to the prior year period. While relatively flat when comparing the first quarter of 2022 and the
equivalent period in 2021, an overall positive trend on service and consulting revenue is expected to continue as the Company expects
that as more of the revenue will be derived from recurring revenue. Costs of revenues on services and consulting are expected to increase
in future years but at a slower rate than revenue growth. The Company focused on streamlining support operations in 2021, and despite
the additional resources allocated to these activities in anticipation of higher recurring revenue in 2022 and beyond, we expect higher
gross margins as the Company grows.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As discussed previously, the impact of inflation may
negatively affect the costs of revenues such that we may experience higher costs for materials and labor, including higher employee and
sub-contractor costs that cannot be passed along in all cases. Management is continuing to monitor this situation and expects to take
actions as the full impact of these cost increases is understood. This may take the form of higher prices and continued evaluation of
costs to attempt to reduce the overall costs to offset the additional expenses, although this is not assured.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As previously discussed, the Company has revamped
its operations to support an anticipated increase in the number of new systems going forward. The resultant additional cost of revenues
was not covered by a comparable increase in revenues during the first quarter of 2022. The main reason for the continuing high level
of cost is higher costs of materials due to supply chain disruptions and inflation. However, we anticipate an improvement in the overall
gross margin for the full year of 2022, with much of the improvement expected to occur in the second half of the year. Certain macro-economic
factors, which are driving increased costs for materials and labor, may result in higher costs for project implementation that cannot
be wholly or even partially passed on to our customers, which may result in delaying our progress towards profitability into 2023.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Overall operating expenses during the three months
ended March 31, 2022 increased by 23% compared to the equivalent period in 2021. Increases in research and development costs and general
and administration costs during the current year period were offset by a decrease in sales and marketing costs during the period. The
overall increase is primarily related to the Company&#8217;s efforts to revamp its operations to support an anticipated increase in the
number of new systems going forward. The increase is also related to higher rent, as during the fourth quarter of 2021, a new operating
lease agreement of office and warehouse combination space commenced. This new space will combine the Company&#8217;s two separate work
locations into one facility, which will allow for greater collaboration and also accommodate a larger anticipated workforce and manufacturing
facility. The increase in research and development costs was also driven by customer demand for the development of new components related
to our technology systems.&#160;</p>

March 31, 2022 and 2021 were $2,641,618 and $1,822,300, respectively. The increase in losses from operations was primarily the result
of lower revenues recorded in the quarter as a consequence of delays in the start of new projects and delays in the receipt of materials
for production. There was also higher relative cost of sales related to higher costs of materials resulting from supply chain disruptions
and inflation.</p>

cash used in operating activities was $827,733. The working capital surplus and accumulated deficit as of March 31, 2022 were $2,540,856
and $48,141,667 respectively. In previous financial reports, the Company had raised substantial doubt about continuing as a going concern.
This was principally due to a lack of working capital prior to an underwritten offering receiving net proceeds of approximately $5,500,000
from the successful sales of common stock which was completed during the first quarter of 2022 (the &#8220;2022 Offering&#8221;).</p>

Company is comfortable that it would be able to raise sufficient capital to support expanded operations based on an anticipated increase

to continue executing the plan described above, generate enough revenue, and attain consistently profitable operations. Although the current
global pandemic related to the coronavirus (COVID-19) has affected our operations, particularly in supply chain, we now believe that this
is expected to be an ongoing issue and our working capital assumptions reflect this new reality. The Company cannot currently quantify
the uncertainty related to the pandemic and its effects on our customers in the coming quarters. We have analyzed our cash flow under
&#8220;stress test&#8221; conditions and have determined that we have sufficient liquid assets on hand to maintain operations for at least
twelve months from the date of this report.</p>

capital for existing operations for 2022, although we may do so to fund selective opportunities that may arise. Management has extensively

service periods of the awards, which is generally the vesting period. The Company&#8217;s determination of fair value using an option-pricing
model is affected by the stock price as well as assumptions regarding a number of highly subjective variables.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company estimates volatility based upon the historical
stock price of the Company and estimates the expected term for stock options using the simplified method for employees and directors and
the contractual term for non-employees. The risk-free rate is determined based upon the prevailing rate of United States Treasury securities
with similar maturities.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company follows Accounting Standards Codification
606, Revenue from Contracts with Customers (&#8220;ASC 606&#8221;), that affects the timing of when certain types of revenues will be
recognized. The basic principles in ASC 606 include the following: a contract with a customer creates distinct contract assets and performance
obligations, satisfaction of a performance obligation creates revenue, and a performance obligation is satisfied upon transfer of control
to a good or service to a customer.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For revenues related to technology systems, the Company
recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete
projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue
to recognize.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Accordingly, the Company now bases its revenue recognition
on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance does not create an asset
with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date including a
profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods are manufactured
and revenue is recognized accordingly.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Under this method, contract revenues are recognized
over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor, subcontract
labor and other allocable indirect costs. All un-allocable indirect costs and corporate general and administrative costs are also charged
to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in &#8220;contract
assets&#8221;. Any billings of customers more than recognized revenues are recorded as a liability in &#8220;contract liabilities&#8221;.
However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 3pc">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates.
The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts receivable,
valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues and the total
estimated costs to determine progress towards contract completion, estimates of the valuation of right of use assets and corresponding
lease liabilities, valuation of warrants issued with debt, and valuation of stock-based awards. We base our estimates on historical experience
and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ
from these estimates.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Duos Technologies Group, Inc. (the &#8220;Company&#8221;),
through its operating subsidiaries, Duos Technologies, Inc. and TrueVue360, Inc. (collectively the &#8220;Company&#8221;), develops and
deploys vision based analytical technology solutions that will help to transform precision railroading, logistics and inter-modal transportation
operations. Additionally, these unique patented solutions can be employed into many other industries.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#8220;AI&#8221;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has built a portfolio of IP and patented
solutions that creates &#8220;actionable intelligence&#8221; using two core native platforms called Centraco&#174; and Praesidium&#8482;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#8482; with the objective of focusing the Company&#8217;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions. The Company also offers
technical support services for the above products.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also provided professional and consulting
services for large data centers and had developed a system for the automation of asset information marketed as DcVue&#8482;. The Company
had deployed its DcVue software at one beta site. This software was used by Duos&#8217; consulting auditing teams. DcVue was based upon
the Company&#8217;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed
software product. The Company ceased offering this product in 2021.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s strategy is to deliver operational
and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics
and U.S. Government Sectors, offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and
improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based
work force where employees enjoy their work and are incentivized to excel and remain with the Company.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these
estimates. The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts
receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues
and the total estimated costs to determine progress towards contract completion, estimates of the valuation of right of use assets and
corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based awards. We base our estimates on
historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual
results may differ from these estimates.</p>

recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Accordingly, the Company bases its technology systems
revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance does
not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192.</p>

revenues are recognized over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material,
direct labor, subcontract labor and other allocable direct costs. All un-allocable indirect costs and corporate general and administrative
costs are also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an
asset in &#8220;contract assets&#8221;. Any billings of customers more than recognized revenues are recorded as a liability in &#8220;contract
liabilities&#8221;. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Each performance obligation is accounted for separately
when each has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each performance obligations is recognized using the applicable criteria under GAAP as discussed above for performance
obligations sold in single performance obligation arrangements. A delivered item or items that do not qualify as a separate unit of accounting
within the arrangement are combined with the other applicable undelivered items within the arrangement. The allocation of arrangement
consideration and the recognition of revenue is then determined for those combined deliverables as a single unit of accounting. The Company
sells its various services and software and hardware products at established prices on a standalone basis which provides Company specific
objective evidence of selling price for purposes of performance obligations relative selling price allocation. The Company only sells
maintenance services or spare parts based on its established rates after it has completed a system integration project for a customer.
The customer is not required to purchase maintenance services. All elements in multiple performance obligations arrangements with Company
customers qualify as separate units of account for revenue recognition purposes.</p>

the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments
and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement
of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We adopted this pronouncement for
our fiscal year beginning January 1, 2022, and it did not have a material effect on our unaudited consolidated financial statements.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="background-color: white">In May 2021,
the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a
material effect on our unaudited consolidated financial statements.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As reflected in the accompanying unaudited consolidated
financial statements, the Company had a net loss of $<span id="xdx_902_eus-gaap--NetIncomeLoss_iN_pp0p0_di_c20220101__20220331_zQ5ujilpAF93" title="Net income">2,644,616</span> for the three months ended March 31, 2022. During the same period, cash
used in operating activities was $<span id="xdx_903_eus-gaap--NetCashProvidedByUsedInOperatingActivities_iN_pp0p0_di_c20220101__20220331_zkbgOo96cw68" title="Net cash used in operations">827,733</span>. The working capital surplus and accumulated deficit as of March 31, 2022 were $<span id="xdx_90A_ecustom--WorkingCapitalDeficit_c20220331_pp0p0" title="Working capital deficit">2,540,856</span> and
$<span id="xdx_900_eus-gaap--RetainedEarningsAccumulatedDeficit_iNI_pp0p0_di_c20220331_zoOOWwGbAYei" title="Accumulated deficit">48,141,667</span>, respectively. In one previous financial report during 2021, the Company had raised substantial doubt about continuing as
a going concern. This was principally due to a lack of working capital prior to an underwritten common stock offering which was completed
during the first quarter of 2022 (the &#8220;2022 Offering&#8221;).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">During the previous 15 months, the Company has raised
more than $10 million after fees and expenses, both from existing shareholders through the issuance of Series C Convertible Preferred
Stock and in the first quarter of 2022, a follow-on common stock offering using its previously filed &#8220;shelf&#8221; registration.
Although, further additional investment is not assured, the Company is comfortable that it would be able to raise sufficient capital to
support expanded operations based on an anticipated increase in business activity. In the long run, the continuation of the Company as
a going concern is dependent upon the ability of the Company to continue executing the plan described above, generate enough revenue,
and eventually attain consistently profitable operations. Although the current global pandemic related to the coronavirus (COVID-19) has
affected our operations, particularly in supply chain, we now believe that this is expected to be an ongoing issue and our working capital
assumptions reflect this new reality. The Company cannot currently quantify the uncertainty related to the pandemic and its effects on
our customers in the coming quarters. We have analyzed our cash flow under &#8220;stress test&#8221; conditions and have determined that
we have sufficient liquid assets on hand to maintain operations for at least twelve months from the date of this report. A notable recent
success is the &#8220;bonding&#8221; secured in the amount of approximately $8 million for a major project for which the Company recently
received full &#8220;notice to proceed&#8221;.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company was successful in securing a loan of
$<span id="xdx_901_eus-gaap--SecuredDebt_c20220331_pp0p0" title="Secured loan">1,410,270</span> during the second quarter of 2020
from the Small Business Administration via the PPP/CARES Act program which further bolstered the Company&#8217;s cash reserves. This
loan was forgiven in the first quarter of 2021 and leaves the Company essentially debt free other than the normal course of business
equipment and insurance financing. The Company has also been successful in increasing its working capital surplus after receiving
proceeds from the 2021 Offering of $4,500,000 and more recently, in the first quarter of 2022, receiving net proceeds of
approximately $<span id="xdx_905_eus-gaap--ProceedsFromOtherDebt_c20220101__20220331_pp0p0" title="Net proceeds bebt">5,500,000</span>
from the successful sales of common stock under the Company&#8217;s &#8220;shelf registration&#8221; statement as previously
mentioned. This gives us the capital required to fund the fundamental business changes that we are executing including organization,
product alignment and market focus and maintenance of our business strategy overall. In addition, management has been taking and
continues to take actions including, but not limited to, elimination of certain costs that do not contribute to short term revenue,
and re-aligning both management and staffing with a focus on improving certain skill sets necessary to build growth and
profitability and focusing product strategy on opportunities that are likely to bear results in the relatively short term. During
2021, management took further significant actions including reorganizing our engineering and technical teams and selectively
improving organizational efficiency to effectively grow the business in concert with the influx of business won in late 2021 and
early 2022. Upon completion of the 2022 Offering, management has raised sufficient working capital to meet its needs for the next
12-months without the need to raise further capital. The Company had experienced a significant slowdown in closing new projects due
to cautious actions by current and potential clients as a result of COVID-19 but this appears to be abating as time passes. We
continue to be successful in identifying new business opportunities and are focused on maintaining a backlog of projects.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><b>&#160;</b></p>






<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Management believes that, at this time, the conditions
in our market space with ongoing contract delays, the consequent need to procure certain materials in advance of a binding contract and
the additional time needed to execute on new contracts previously reported have put a strain on our cash reserves. However, recent events
including an approximate $5.5 million injection of funds from a sale of common stock, significant recent orders and the overall stabilization
of the business indicate that there is no longer substantial doubt for the Company to continue as a going concern for a period of twelve
months from the issuance of this report. We will continue executing the plan to grow our business and eventually achieve profitability
without the requirement to raise additional capital for existing operations for 2022 although we may do so to fund selective opportunities
that may arise. Management has extensively evaluated our requirements for the next 12 months and has determined that the Company currently
has sufficient cash to operate for at least that period.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On July 26, 2021, the Company entered a new operating
lease agreement of office and warehouse combination space of <span id="xdx_90B_ecustom--AreaOfLease_usqft_c20210702__20210726_zIvQEazaxAe2" title="Area of Lease">40,000</span> square feet, with the lease commencing on November 1, 2021 and ending
April 30, 2032. This new space will combine the Company&#8217;s two separate work locations into one facility, which will allow for greater
collaboration and also accommodate a larger anticipated workforce and manufacturing facility. On November 24, 2021, the lease was amended
to commence on December 1, 2021 and end on May 31, 2032. The Company recognized a ROU asset and operating lease liability in the amount
of $<span id="xdx_902_eus-gaap--OperatingLeaseLiabilityCurrent_iI_pp0p0_c20211124_zudYA8XX7dia" title="Operating lease liability">4,980,104</span> at lease commencement. Rent for the first eleven months of the term will be calculated based on <span id="xdx_907_ecustom--RentableSpace_usqft_c20210702__20210726_zqZKRMp3ELnb" title="Rentable Space">30,000</span> rentable square feet.
The rent is subject to an annual escalation of 2.5%, beginning November 1, 2023. The Company made a security deposit payment in the amount
of $<span id="xdx_902_eus-gaap--SecurityDepositLiability_c20210726_pp0p0" title="Security Deposit payment">600,000</span> on July 26, 2021.

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">As of March 31, 2022, the office and warehouse lease
is the Company&#8217;s only lease with a term greater than twelve months. The office and warehouse lease has a remaining term of approximately
10.2 years and includes an option to extend for two renewal terms of five years each. The renewal options are not reasonably certain to
be exercised, and therefore, they are not included when determining the lease term used to establish the right-of use asset and lease
liability. The Company also has several short-term leases, primarily related to equipment. The Company made an accounting policy election
to not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in
expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components (such
as common area maintenance) as a single lease component.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On July 10, 2020, the Company announced that Gianni
Arcaini would retire from the positions of Chief Executive Officer and Chairman of the Board effective as of September 1, 2020 (the &#8220;CEO
Transition&#8221;). In order to facilitate a transition of his duties, the Company and Mr. Arcaini entered into a separation agreement
which became effective as of July 10, 2020 (the &#8220;Separation Agreement&#8221;). Pursuant to the Separation Agreement, Mr. Arcaini&#8217;s
employment with the Company ended on September 1, 2020 (&#8220;Separation Date&#8221;) and he will receive separation payments over a
36-month period equal to his base salary plus $<span id="xdx_90F_ecustom--AdditionalCompensationToBePaidInSeparationPayments_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Compensation to be paid in addition to base salary in separation payments">75,000</span> as well as certain limited health and life insurance benefits. The Separation Agreement
also contains confidentiality, non-disparagement and non-solicitation covenants and a release of claims by Mr. Arcaini who continued to
serve as Chairman of the Board of Directors of the Company. The Corporate Governance and Nominating Committee did not submit Mr. Arcaini
for re-election as a director and on November 19, 2020 at the Annual Shareholders meeting a new non-Executive Chairman was appointed.</p>

Notwithstanding the foregoing, the status of Mr. Arcaini as a &#8220;Specified Employee&#8221;
as defined in Internal Revenue Code Section 409A has the effect of delaying any payments to Mr. Arcaini under the Separation Agreement
for six months after the Separation Date. On March 1, 2021, the Company paid to Mr. Arcaini a lump-sum amount equal to the first six months
of payments, or $<span id="xdx_90D_ecustom--PaymentOneOfSeparationAgreement_c20210302__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Lump sum payment owed under separation agreement">124,631</span>, owed to Mr. Arcaini and the Company will continue to pay him in semi-monthly installments for 30 months thereafter,

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company generates revenue from four sources: (1)
Technology Systems; (2) AI Technology which is included in the consolidated statements of operations line-item Technology systems; (3)
Technical Support; and (4) Consulting Services which is included in the unaudited consolidated statements of operations line-item Services

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company constructs intelligent technology systems
consisting of materials and labor under customer contracts. Revenues and related costs on technology systems revenue are recognized based
on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance does not create an asset
with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date including a
profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods are manufactured
and revenue is recognized accordingly.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>







<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Under this method, contract revenues are recognized
over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor,
subcontract labor and other allocable direct costs. All un-allocable indirect costs and corporate general and administrative costs are
also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in
&#8220;contract assets&#8221;. Any billings of customers more than recognized revenues are recorded as a liability in &#8220;contract
liabilities&#8221;. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">A contract is considered complete when all costs except
insignificant items have been incurred and the installation is operating according to specifications or has been accepted by the customer.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has contracts in various stages of completion.
Such contracts require estimates to determine the appropriate cost and revenue recognition. Cost estimates are reviewed periodically on
a contract-by-contract basis throughout the life of the contract such that adjustments to the profit resulting from revisions are made
cumulative to the date of the revision. Significant management judgments and estimates, including the estimated costs to complete projects,
must be made and used in connection with the revenue recognized in the accounting period. Current estimates may be revised as additional
information becomes available.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">On August 1, 2012, the Company entered into an
independent contractor master services agreement (the &#8220;Services Agreement&#8221;) with Luceon, LLC, a Florida limited
liability company, owned by our former Chief Technology Officer, David Ponevac.&#160;The Services Agreement provided that Luceon
would provide support services including management, coordination or software development services and related services to duos. In
January 2019, additional services were contracted with Luceon for TrueVue360&#8482; primarily for software development through the
provision of 7 additional full-time contractors located in Slovakia at a cost of $<span id="xdx_90C_eus-gaap--RelatedPartyCosts_c20190101__20190131_pp0p0" title="Related party cost">16,250</span>
for January initially, rising to $<span id="xdx_904_eus-gaap--RelatedPartyCosts_c20190201__20190228_pp0p0" title="Related party cost">25,583</span>
after fully staffed, per month starting February 2019. This was in addition to the existing contract of $<span id="xdx_90A_eus-gaap--RelatedPartyCosts_c20190601__20190630__srt--ProductOrServiceAxis__custom--ContractorsMember_pp0p0" title="Related party cost">7,480</span>
per month for duos for 4 full-time contractors which increased to $8,231 per month in June of 2019. During 2020 efforts in reducing
cost, Luceon reduced its staff for the TrueVue360 software development team from a staff of 7 to 3 full-time employees at a cost of
$11,666 per month starting June 1, 2020. As of January 1, 2021, the Company no longer records activities in TrueVue360 and has
combined billings for a total of $<span id="xdx_902_eus-gaap--AccountsPayableRelatedPartiesCurrentAndNoncurrent_c20210102_pp0p0" title="Accounts payable">20,986</span>
per month. For the three months ended March 31, 2022 and 2021, the total amount expensed is zero <span id="xdx_90B_eus-gaap--RelatedPartyCosts_c20220101__20220331_pp0p0" style="display: none" title="Related party cost">0</span> and $<span id="xdx_909_eus-gaap--RelatedPartyCosts_c20210101__20210331_pp0p0" title="Related party cost">62,958</span>, respectively. The
Company had no open accounts payable with Luceon at March 31, 2022. On May 14, 2021, the Company formally ended its relationship
with Luceon in concert with the resignation of our Chief Technology Officer and as such there is no longer a related party
relationship.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Duos Technologies Group, Inc. (the &#8220;Company&#8221;),
through its operating subsidiaries, Duos Technologies, Inc. and TrueVue360, Inc. (collectively the &#8220;Company&#8221;), develops and
deploys vision based analytical technology solutions that will help to transform precision railroading, logistics and inter-modal transportation
operations. Additionally, these unique patented solutions can be employed into many other industries.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#8220;AI&#8221;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company has built a portfolio of IP and patented
solutions that creates &#8220;actionable intelligence&#8221; using two core native platforms called Centraco&#174; and Praesidium&#8482;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#8482; with the objective of focusing the Company&#8217;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions. The Company also offers
technical support services for the above products.</p>

services for large data centers and had developed a system for the automation of asset information marketed as DcVue&#8482;. The Company
had deployed its DcVue software at one beta site. This software was used by Duos&#8217; consulting auditing teams. DcVue was based upon
the Company&#8217;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed
software product. The Company ceased offering this product in 2021.</p>

with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these
estimates. The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts
receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues
and the total estimated costs to determine progress towards contract completion, estimates of the valuation of right of use assets and
corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based awards. We base our estimates on
historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual
results may differ from these estimates.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For revenues related to technology systems, the Company
recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete
projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue
to recognize.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Accordingly, the Company bases its technology systems
revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#8217;s performance does
not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span id="a_Hlk103255145"/>Under this method, contract
revenues are recognized over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material,
direct labor, subcontract labor and other allocable direct costs. All un-allocable indirect costs and corporate general and administrative
costs are also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an
asset in &#8220;contract assets&#8221;. Any billings of customers more than recognized revenues are recorded as a liability in &#8220;contract
liabilities&#8221;. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Each performance obligation is accounted for separately
when each has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each performance obligations is recognized using the applicable criteria under GAAP as discussed above for performance
obligations sold in single performance obligation arrangements. A delivered item or items that do not qualify as a separate unit of accounting
within the arrangement are combined with the other applicable undelivered items within the arrangement. The allocation of arrangement
consideration and the recognition of revenue is then determined for those combined deliverables as a single unit of accounting. The Company
sells its various services and software and hardware products at established prices on a standalone basis which provides Company specific
objective evidence of selling price for purposes of performance obligations relative selling price allocation. The Company only sells
maintenance services or spare parts based on its established rates after it has completed a system integration project for a customer.
The customer is not required to purchase maintenance services. All elements in multiple performance obligations arrangements with Company
customers qualify as separate units of account for revenue recognition purposes.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">From time to time, the FASB or other standards setting
bodies will issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an Accounting Standards
Update (&#8220;ASU&#8221;).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="background-color: white">In August 2020,
the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments
and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement
of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We adopted this pronouncement for
our fiscal year beginning January 1, 2022, and it did not have a material effect on our unaudited consolidated financial statements.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="background-color: white">In May 2021,
the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a
material effect on our unaudited consolidated financial statements.</span></p>

issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.</p>

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Duos Technologies Group, Inc. (the &#x201c;Company&#x201d;),
through its operating subsidiaries, Duos Technologies, Inc. and TrueVue360, Inc. (collectively the &#x201c;Company&#x201d;), develops and
deploys vision based analytical technology solutions that will help to transform precision railroading, logistics and inter-modal transportation
operations. Additionally, these unique patented solutions can be employed into many other industries.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#x201c;AI&#x201d;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has built a portfolio of IP and patented
solutions that creates &#x201c;actionable intelligence&#x201d; using two core native platforms called Centraco&#xae; and Praesidium&#x2122;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#x2122; with the objective of focusing the Company&#x2019;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions. The Company also offers
technical support services for the above products.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company also provided professional and consulting
services for large data centers and had developed a system for the automation of asset information marketed as DcVue&#x2122;. The Company
had deployed its DcVue software at one beta site. This software was used by Duos&#x2019; consulting auditing teams. DcVue was based upon
the Company&#x2019;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed
software product. The Company ceased offering this product in 2021.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s strategy is to deliver operational
and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics
and U.S. Government Sectors, offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and
improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based
work force where employees enjoy their work and are incentivized to excel and remain with the Company.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information
and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (all of which are
of a normal recurring nature) considered necessary for a fair presentation have been included. Operating results for the three months
ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022 or for any
other future period. These unaudited consolidated financial statements and the unaudited condensed notes thereto should be read in conjunction
with the audited consolidated financial statements and notes thereto included in the Company&#x2019;s Annual Report on Form 10-K for the

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these
estimates. The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts
receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues
and the total estimated costs to determine progress towards contract completion, estimates of the valuation of right of use assets and
corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based awards. We base our estimates on
historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual
results may differ from these estimates.&lt;/p&gt;

at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted
accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure
about such fair value measurements.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;ASC&#160;820 defines fair value as the price that
would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement
date. Additionally, ASC&#160;820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the
use of unobservable inputs.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company analyzes all financial instruments with
features of both liabilities and equity under the Financial Accounting Standard Board&#x2019;s (&#x201c;FASB&#x201d;) accounting standard
for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level
of input that is significant to the fair value measurement.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The estimated fair value of certain financial instruments,
including accounts receivable, prepaid expense, accounts payable, accrued expenses and notes payable are carried at historical cost basis,

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Software development costs incurred prior to establishing
technological feasibility are charged to operations and included in research and development costs. The technological feasibility of a
software product is established when the Company has completed all planning, designing, coding, and testing activities that are necessary
to establish that the product meets its design specifications, including functionality, features, and technical performance requirements.
Software development costs incurred after establishing technological&#160;feasibility for software sold as a perpetual license, as defined
within ASC 985-20 (Software &#x2013; Costs of Software to be Sold, Leased, or Marketed) are capitalized and amortized on a product-by-product

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Basic earnings per share (EPS) are computed by dividing
net loss applicable to common stock by the weighted average number of common shares outstanding. Diluted net loss per common share is
computed by dividing the net loss applicable to common stock by the weighted average number of common shares outstanding for the period
and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares
issuable upon the exercise or conversion of stock options, stock warrants, convertible debt instruments, convertible preferred stock or
other common stock equivalents. Potentially dilutive securities are excluded from the computation if their effect is anti-dilutive. At
March 31, 2022, there was an aggregate of &lt;span id="xdx_901_eus-gaap--ClassOfWarrantOrRightOutstanding_c20220331_pdd" title="Number of Warrants Outstanding"&gt;1,376,466&lt;/span&gt; outstanding warrants to purchase shares of common stock. At March 31, 2022, there

value. Accounts receivable are comprised of balances due from customers net of estimated allowances for uncollectible accounts. In determining
the collections on the account, historical trends are evaluated, and specific customer issues are reviewed to arrive at appropriate allowances.
The Company reviews its accounts to estimate losses resulting from the inability of its customers to make required payments. Any required
allowance is based on specific analysis of past due accounts and also considers historical trends of write-offs. Past due status is based
on how recently payments have been received from customers.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company follows Accounting Standards Codification
606, Revenue from Contracts with Customers (&#x201c;ASC 606&#x201d;), that affects the timing of when certain types of revenues will be
recognized. The basic principles in ASC 606 include the following: a contract with a customer creates distinct contract assets and performance
obligations, satisfaction of a performance obligation creates revenue, and a performance obligation is satisfied upon transfer of control
to a good or service to a customer.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Revenue is recognized by evaluating our revenue contracts
with customers based on the five-step model under ASC 606:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company generates revenues from four sources:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 24px"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 24px"&gt;1.&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Technology Systems;&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 24px"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 24px"&gt;2.&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;AI Technology;&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 24px"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 24px"&gt;3.&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Technical Support; and&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 24px"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 24px"&gt;4.&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Consulting Services.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For revenues related to technology systems, the Company
recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete
projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue
to recognize.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Accordingly, the Company bases its technology systems
revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#x2019;s performance does
not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Hlk103255145"/&gt;Under this method, contract
revenues are recognized over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material,
direct labor, subcontract labor and other allocable direct costs. All un-allocable indirect costs and corporate general and administrative
costs are also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an
asset in &#x201c;contract assets&#x201d;. Any billings of customers more than recognized revenues are recorded as a liability in &#x201c;contract
liabilities&#x201d;. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has revenue from applications that incorporate
artificial intelligence (AI) in the form of predetermined algorithms which provide important operating information to the users of our
systems. The revenue generated from these applications of AI consists of a fixed fee related to the design, development, testing and incorporation
of new algorithms into the system, which is recognized as revenue at a point in time upon acceptance, as well as an annual application
maintenance fee, which is recognized as revenue ratably over the contracted maintenance term. &#160;&lt;/p&gt;

&lt;p style="font: 10pt Calibri, Helvetica, Sans-Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Technical support services are provided on both an
as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided outside of
a maintenance contract are on an &#x201c;as-requested&#x201d; basis, and revenue is recognized over time as the services are provided. Revenue
for maintenance and technical support provided on an extended-term basis is recognized over time ratably over the term of the contract.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s consulting services business generates
revenues under contracts with customers from three sources: (1) Professional Services (consulting and auditing); (2) Software licensing
with optional hardware sales; and (3) Customer service training and (4) Maintenance support.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 24px"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 24px"&gt;(1)&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Revenues for professional services, which are of short-term duration, are recognized when services are completed;&lt;/td&gt;&lt;/tr&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td&gt;&#160;&lt;/td&gt;
    &lt;td&gt;(2)&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;For all periods reflected in this report, software license sales have been one-time sales of a perpetual license to use our software product and the customer also has the option to purchase third-party manufactured handheld devices from us if they purchase our software license. Accordingly, the revenue is recognized upon delivery of the software and delivery of the hardware, as applicable, to the customer;&lt;/td&gt;&lt;/tr&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td&gt;&#160;&lt;/td&gt;
    &lt;td&gt;(3)&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Training sales are one-time upfront short-term training sessions and are recognized after the service has been performed; and&lt;/td&gt;&lt;/tr&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td&gt;&#160;&lt;/td&gt;
    &lt;td&gt;(4)&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Maintenance/support is an optional product sold to our software license customers under one-year contracts. Accordingly, maintenance payments received upfront are deferred and recognized over the contract term.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;






&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"/&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p id="xdx_843_ecustom--MultiplePerformanceObligationsAndAllocationOfTransactionPricePolicyTextBlock_zLqV05UrH8h2" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&lt;span id="xdx_86C_zWR6IyNFoRYb"&gt;Multiple Performance Obligations and Allocation
of Transaction Price&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Arrangements with customers may involve multiple &lt;span id="a_Hlk103347545"/&gt;performance
obligations including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur
after the project is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business,
multiple performance obligations may include any of the above four sources. Training and maintenance on software products may occur after
the software product sale while other services may occur before or after the software product sale and may not relate to the software
product. Revenue recognition for a multiple performance obligations arrangement is as follows:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Each performance obligation is accounted for separately
when each has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each performance obligations is recognized using the applicable criteria under GAAP as discussed above for performance
obligations sold in single performance obligation arrangements. A delivered item or items that do not qualify as a separate unit of accounting
within the arrangement are combined with the other applicable undelivered items within the arrangement. The allocation of arrangement
consideration and the recognition of revenue is then determined for those combined deliverables as a single unit of accounting. The Company
sells its various services and software and hardware products at established prices on a standalone basis which provides Company specific
objective evidence of selling price for purposes of performance obligations relative selling price allocation. The Company only sells
maintenance services or spare parts based on its established rates after it has completed a system integration project for a customer.
The customer is not required to purchase maintenance services. All elements in multiple performance obligations arrangements with Company
customers qualify as separate units of account for revenue recognition purposes.&lt;/p&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&#160;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p id="xdx_842_eus-gaap--SegmentReportingPolicyPolicyTextBlock_z9pIU4vZecVa" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&lt;span id="xdx_869_zOUq7uPOjX8"&gt;Segment Information&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company operates in one reportable segment.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p id="xdx_84E_eus-gaap--ShareholdersEquityAndShareBasedPaymentsTextBlock_zCqkyUHKJRs6" style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&lt;span id="xdx_866_zDdz7Ndo72Ac"&gt;Stock-Based Compensation&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for employee and non-employee
stock-based compensation in accordance with ASC 718-10, &#x201c;&lt;i&gt;Share-Based Payment&lt;/i&gt;,&#x201d; which requires the grant date measurement
and the recognition of compensation expense for all share-based payment awards made including employee stock options, restricted stock
units, and employee stock purchases based on estimated fair values.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Determining Fair Value Under ASC 718-10&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates the fair value of stock options
granted using the Black-Scholes option-pricing formula. This fair value is then amortized on a straight-line basis over the requisite
service periods of the awards, which is generally the vesting period. The Company&#x2019;s determination of fair value using an option-pricing
model is affected by the stock price as well as assumptions regarding the number of highly subjective variables.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates volatility based upon the historical
stock price of the Company and estimates the expected term for stock options using the simplified method for employees and directors and
the contractual term for non-employees. The risk-free rate is determined based upon the prevailing rate of United States Treasury securities
with similar maturities.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p id="xdx_848_eus-gaap--LesseeLeasesPolicyTextBlock_z40Q0A5G9D06" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&lt;span id="xdx_863_zhxOUG9ow5M1"&gt;Leases&lt;/span&gt;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company follows ASC 842 &#x201c;Leases&#x201d;.
This guidance requires lessees to recognize right-of-use (&#x201c;ROU&#x201d;) assets and lease liabilities for most operating leases. In
addition, this guidance requires that lessors separate lease and non-lease components in a contract in accordance with the revenue guidance
in ASC 606.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company made an accounting policy election to
not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in expense
as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components as a single
lease component.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;At the inception of a contract the Company assesses
whether the contract is, or contains, a lease. The Company&#x2019;s assessment is based on: (1) whether the contract involves the use of
a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout
the period, and (3) whether it has the right to direct the use of the asset.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Operating ROU assets represent the right to use the
leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over
the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based
on the information available at the lease commencement date to determine the present value of future payments. The lease term includes
all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not
to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included
in general and administrative expenses in the consolidated statements of operations.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;From time to time, the FASB or other standards setting
bodies will issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an Accounting Standards
Update (&#x201c;ASU&#x201d;).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;In August 2020,
the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments
and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement
of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We adopted this pronouncement for
our fiscal year beginning January 1, 2022, and it did not have a material effect on our unaudited consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;In May 2021,
the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a
material effect on our unaudited consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Management does not believe that any other recently
issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying financial statements.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Duos Technologies Group, Inc. (the &#x201c;Company&#x201d;),
through its operating subsidiaries, Duos Technologies, Inc. and TrueVue360, Inc. (collectively the &#x201c;Company&#x201d;), develops and
deploys vision based analytical technology solutions that will help to transform precision railroading, logistics and inter-modal transportation
operations. Additionally, these unique patented solutions can be employed into many other industries.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has developed the Railcar Inspection Portal
(RIP) that provides both freight and transit railroad customers and select government agencies the ability to conduct fully automated
inspections of trains while they are in transit. The system, which incorporates a variety of sophisticated optical technologies, illumination
and other sensors, scans each passing railcar to create an extremely high-resolution image set from a variety of angles including the
undercarriage. These images are then processed through various methods of artificial intelligence (&#x201c;AI&#x201d;) algorithms to identify
specific defects and/or areas of interest on each railcar. This is all accomplished within minutes of a railcar passing through our portal.
This solution has the potential to transform the railroad industry by increasing safety, improving efficiency and reducing costs. The
Company has successfully deployed this system with several Class 1 railroad customers and anticipates an increased demand in the future.
Government agencies can conduct digital inspections combined with the incorporated AI to improve rail traffic flow across borders which
also directly benefits the Class 1 railroads through increasing their velocity.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has also developed the Automated Logistics
Information System (ALIS) which automates and reduces/removes personnel from gatehouses where trucks enter and exit large logistics and
intermodal facilities. This solution also incorporates sensors and data points as necessary for each operation and directly interconnects
with backend logistics databases and processes to streamline operations and significantly improve operations and security and importantly
dramatically improves the vehicle throughput on each lane on which the technology is deployed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has built a portfolio of IP and patented
solutions that creates &#x201c;actionable intelligence&#x201d; using two core native platforms called Centraco&#xae; and Praesidium&#x2122;.
All solutions provided include a variant of both applications. Centraco is designed primarily as the user interface to all our systems
as well as the backend connection to third-party applications and databases through both Application Programming Interfaces (APIs) and
Software Development Kits (SDKs). This interface is browser based and hosted within each one of our systems and solutions. It is typically
also customized for each unique customer and application. Praesidium typically resides as middleware in our systems and manages the various
image capture devices and some sensors for input into the Centraco software.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company also developed a proprietary Artificial
Intelligence (AI) software platform, Truevue360&#x2122; with the objective of focusing the Company&#x2019;s advanced intelligent technologies
in the areas of AI, deep machine learning and advanced multi-layered algorithms to further support our solutions. The Company also offers
technical support services for the above products.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company also provided professional and consulting
services for large data centers and had developed a system for the automation of asset information marketed as DcVue&#x2122;. The Company
had deployed its DcVue software at one beta site. This software was used by Duos&#x2019; consulting auditing teams. DcVue was based upon
the Company&#x2019;s OSPI patent which was awarded in 2010. The Company offered DcVue available for license to our customers as a licensed
software product. The Company ceased offering this product in 2021.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s strategy is to deliver operational
and technical excellence to our customers, expand our RIP and ALIS solutions into current and new customers focused in the Rail, Logistics
and U.S. Government Sectors, offer both CAPEX and OPEX pricing models to customers that increases recurring revenue, grows backlog and
improves profitability, responsibly grow the business both organically and through selective acquisitions, and promote a performance-based
work force where employees enjoy their work and are incentivized to excel and remain with the Company.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these
estimates. The most significant estimates in the accompanying unaudited consolidated financial statements include the allowance on accounts
receivable, valuation of deferred tax assets, valuation of intangible and other long-lived assets, estimates of net contract revenues
and the total estimated costs to determine progress towards contract completion, estimates of the valuation of right of use assets and
corresponding lease liabilities, valuation of warrants issued with debt and valuation of stock-based awards. We base our estimates on
historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual
results may differ from these estimates.&lt;/p&gt;

at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted
accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure
about such fair value measurements.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;ASC&#160;820 defines fair value as the price that
would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement
date. Additionally, ASC&#160;820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the
use of unobservable inputs.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company analyzes all financial instruments with
features of both liabilities and equity under the Financial Accounting Standard Board&#x2019;s (&#x201c;FASB&#x201d;) accounting standard
for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level
of input that is significant to the fair value measurement.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The estimated fair value of certain financial instruments,
including accounts receivable, prepaid expense, accounts payable, accrued expenses and notes payable are carried at historical cost basis,

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Basic earnings per share (EPS) are computed by dividing
net loss applicable to common stock by the weighted average number of common shares outstanding. Diluted net loss per common share is
computed by dividing the net loss applicable to common stock by the weighted average number of common shares outstanding for the period
and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares
issuable upon the exercise or conversion of stock options, stock warrants, convertible debt instruments, convertible preferred stock or
other common stock equivalents. Potentially dilutive securities are excluded from the computation if their effect is anti-dilutive. At

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Accounts receivable are stated at estimated net realizable

the collections on the account, historical trends are evaluated, and specific customer issues are reviewed to arrive at appropriate allowances.
The Company reviews its accounts to estimate losses resulting from the inability of its customers to make required payments. Any required
allowance is based on specific analysis of past due accounts and also considers historical trends of write-offs. Past due status is based
on how recently payments have been received from customers.&lt;/p&gt;

606, Revenue from Contracts with Customers (&#x201c;ASC 606&#x201d;), that affects the timing of when certain types of revenues will be
recognized. The basic principles in ASC 606 include the following: a contract with a customer creates distinct contract assets and performance
obligations, satisfaction of a performance obligation creates revenue, and a performance obligation is satisfied upon transfer of control
to a good or service to a customer.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company generates revenues from four sources:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;

    &lt;td style="text-align: justify"&gt;Technology Systems;&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

    &lt;td style="width: 24px"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 24px"&gt;2.&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;AI Technology;&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 24px"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 24px"&gt;3.&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Technical Support; and&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 24px"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 24px"&gt;4.&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Consulting Services.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For revenues related to technology systems, the Company
recognizes revenue over time using a cost-based input methodology in which significant judgment is required to estimate costs to complete
projects. These estimated costs are then used to determine the progress towards contract completion and the corresponding amount of revenue
to recognize.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Accordingly, the Company bases its technology systems
revenue recognition on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#x2019;s performance does
not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed
to date including a profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods
are manufactured and revenue is recognized accordingly.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation. To accurately reflect revenue recognition based on the input method, the Company
has adopted the implementation guidance as set out in ASC-606-10-55-187 through 192.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Hlk103255145"/&gt;Under this method, contract
revenues are recognized over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material,
direct labor, subcontract labor and other allocable direct costs. All un-allocable indirect costs and corporate general and administrative
costs are also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an
asset in &#x201c;contract assets&#x201d;. Any billings of customers more than recognized revenues are recorded as a liability in &#x201c;contract
liabilities&#x201d;. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has revenue from applications that incorporate
artificial intelligence (AI) in the form of predetermined algorithms which provide important operating information to the users of our
systems. The revenue generated from these applications of AI consists of a fixed fee related to the design, development, testing and incorporation
of new algorithms into the system, which is recognized as revenue at a point in time upon acceptance, as well as an annual application
maintenance fee, which is recognized as revenue ratably over the contracted maintenance term. &#160;&lt;/p&gt;

&lt;p style="font: 10pt Calibri, Helvetica, Sans-Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Technical support services are provided on both an
as-needed and extended-term basis and may include providing both parts and labor. Maintenance and technical support provided outside of
a maintenance contract are on an &#x201c;as-requested&#x201d; basis, and revenue is recognized over time as the services are provided. Revenue
for maintenance and technical support provided on an extended-term basis is recognized over time ratably over the term of the contract.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s consulting services business generates
revenues under contracts with customers from three sources: (1) Professional Services (consulting and auditing); (2) Software licensing
with optional hardware sales; and (3) Customer service training and (4) Maintenance support.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

    &lt;td style="width: 24px"&gt;(1)&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Revenues for professional services, which are of short-term duration, are recognized when services are completed;&lt;/td&gt;&lt;/tr&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td&gt;&#160;&lt;/td&gt;
    &lt;td&gt;(2)&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;For all periods reflected in this report, software license sales have been one-time sales of a perpetual license to use our software product and the customer also has the option to purchase third-party manufactured handheld devices from us if they purchase our software license. Accordingly, the revenue is recognized upon delivery of the software and delivery of the hardware, as applicable, to the customer;&lt;/td&gt;&lt;/tr&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td&gt;&#160;&lt;/td&gt;
    &lt;td&gt;(3)&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Training sales are one-time upfront short-term training sessions and are recognized after the service has been performed; and&lt;/td&gt;&lt;/tr&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td&gt;&#160;&lt;/td&gt;
    &lt;td&gt;(4)&lt;/td&gt;
    &lt;td style="text-align: justify"&gt;Maintenance/support is an optional product sold to our software license customers under one-year contracts. Accordingly, maintenance payments received upfront are deferred and recognized over the contract term.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Arrangements with customers may involve multiple &lt;span id="a_Hlk103347545"/&gt;performance
obligations including project revenue and maintenance services in our Intelligent Technology Systems business. Maintenance will occur
after the project is completed and may be provided on an extended-term basis or on an as-needed basis. In our consulting services business,
multiple performance obligations may include any of the above four sources. Training and maintenance on software products may occur after
the software product sale while other services may occur before or after the software product sale and may not relate to the software
product. Revenue recognition for a multiple performance obligations arrangement is as follows:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Each performance obligation is accounted for separately
when each has value to the customer on a standalone basis and there is Company specific objective evidence of selling price of each deliverable.
For revenue arrangements with multiple deliverables, the Company allocates the total customer arrangement to the separate units of accounting
based on their relative selling prices as determined by the price of the items when sold separately. Once the selling price is allocated,
the revenue for each performance obligations is recognized using the applicable criteria under GAAP as discussed above for performance
obligations sold in single performance obligation arrangements. A delivered item or items that do not qualify as a separate unit of accounting
within the arrangement are combined with the other applicable undelivered items within the arrangement. The allocation of arrangement
consideration and the recognition of revenue is then determined for those combined deliverables as a single unit of accounting. The Company
sells its various services and software and hardware products at established prices on a standalone basis which provides Company specific
objective evidence of selling price for purposes of performance obligations relative selling price allocation. The Company only sells
maintenance services or spare parts based on its established rates after it has completed a system integration project for a customer.
The customer is not required to purchase maintenance services. All elements in multiple performance obligations arrangements with Company
customers qualify as separate units of account for revenue recognition purposes.&lt;/p&gt;
&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;&#160;&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company accounts for employee and non-employee
stock-based compensation in accordance with ASC 718-10, &#x201c;&lt;i&gt;Share-Based Payment&lt;/i&gt;,&#x201d; which requires the grant date measurement
and the recognition of compensation expense for all share-based payment awards made including employee stock options, restricted stock
units, and employee stock purchases based on estimated fair values.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates the fair value of stock options
granted using the Black-Scholes option-pricing formula. This fair value is then amortized on a straight-line basis over the requisite
service periods of the awards, which is generally the vesting period. The Company&#x2019;s determination of fair value using an option-pricing
model is affected by the stock price as well as assumptions regarding the number of highly subjective variables.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company estimates volatility based upon the historical
stock price of the Company and estimates the expected term for stock options using the simplified method for employees and directors and
the contractual term for non-employees. The risk-free rate is determined based upon the prevailing rate of United States Treasury securities
with similar maturities.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company follows ASC 842 &#x201c;Leases&#x201d;.
This guidance requires lessees to recognize right-of-use (&#x201c;ROU&#x201d;) assets and lease liabilities for most operating leases. In
addition, this guidance requires that lessors separate lease and non-lease components in a contract in accordance with the revenue guidance
in ASC 606.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company made an accounting policy election to
not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in expense
as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components as a single
lease component.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;At the inception of a contract the Company assesses
whether the contract is, or contains, a lease. The Company&#x2019;s assessment is based on: (1) whether the contract involves the use of
a distinct identified asset, (2) whether we obtain the right to substantially all the economic benefit from the use of the asset throughout
the period, and (3) whether it has the right to direct the use of the asset.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Operating ROU assets represent the right to use the
leased asset for the lease term and operating lease liabilities are recognized based on the present value of minimum lease payments over
the lease term at commencement date. As most leases do not provide an implicit rate, the Company uses an incremental borrowing rate based
on the information available at the lease commencement date to determine the present value of future payments. The lease term includes
all periods covered by renewal and termination options where the Company is reasonably certain to exercise the renewal options or not
to exercise the termination options. Operating lease expense is recognized on a straight-line basis over the lease term and is included
in general and administrative expenses in the consolidated statements of operations.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;From time to time, the FASB or other standards setting
bodies will issue new accounting pronouncements. Updates to the FASB ASC are communicated through issuance of an Accounting Standards
Update (&#x201c;ASU&#x201d;).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;In August 2020,
the FASB issued an accounting pronouncement (ASU 2020-06) related to the measurement and disclosure requirements for convertible instruments
and contracts in an entity's own equity. The pronouncement simplifies and adds disclosure requirements for the accounting and measurement
of convertible instruments and the settlement assessment for contracts in an entity's own equity. This pronouncement is effective for
fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2023. We adopted this pronouncement for
our fiscal year beginning January 1, 2022, and it did not have a material effect on our unaudited consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="background-color: white"&gt;In May 2021,
the FASB issued an accounting pronouncement (ASU 2021-04) related to modifications or exchanges of freestanding equity-classified written
call options (such as warrants) that remain equity classified after modification or exchange. The pronouncement states that an entity
should treat the modification as an exchange of the original instrument for a new instrument, and the effect of the modification should
be calculated as the difference between the fair value of the modified instrument and the fair value of that instrument immediately before
modification. An entity should then recognize the effect of the modification on the basis of the substance of the transaction, in the
same manner as if cash had been paid as consideration. This pronouncement is effective for fiscal years, and for interim periods within
those fiscal years, beginning after December 15, 2021. The pronouncement will be applied prospectively to all modifications that occur
after the initial date of adoption. We adopted this pronouncement for our fiscal year beginning January 1, 2022, and it did not have a
material effect on our unaudited consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As reflected in the accompanying unaudited consolidated
financial statements, the Company had a net loss of $&lt;span id="xdx_902_eus-gaap--NetIncomeLoss_iN_pp0p0_di_c20220101__20220331_zQ5ujilpAF93" title="Net income"&gt;2,644,616&lt;/span&gt; for the three months ended March 31, 2022. During the same period, cash
used in operating activities was $&lt;span id="xdx_903_eus-gaap--NetCashProvidedByUsedInOperatingActivities_iN_pp0p0_di_c20220101__20220331_zkbgOo96cw68" title="Net cash used in operations"&gt;827,733&lt;/span&gt;. The working capital surplus and accumulated deficit as of March 31, 2022 were $&lt;span id="xdx_90A_ecustom--WorkingCapitalDeficit_c20220331_pp0p0" title="Working capital deficit"&gt;2,540,856&lt;/span&gt; and
$&lt;span id="xdx_900_eus-gaap--RetainedEarningsAccumulatedDeficit_iNI_pp0p0_di_c20220331_zoOOWwGbAYei" title="Accumulated deficit"&gt;48,141,667&lt;/span&gt;, respectively. In one previous financial report during 2021, the Company had raised substantial doubt about continuing as
a going concern. This was principally due to a lack of working capital prior to an underwritten common stock offering which was completed
during the first quarter of 2022 (the &#x201c;2022 Offering&#x201d;).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;During the previous 15 months, the Company has raised
more than $10 million after fees and expenses, both from existing shareholders through the issuance of Series C Convertible Preferred
Stock and in the first quarter of 2022, a follow-on common stock offering using its previously filed &#x201c;shelf&#x201d; registration.
Although, further additional investment is not assured, the Company is comfortable that it would be able to raise sufficient capital to
support expanded operations based on an anticipated increase in business activity. In the long run, the continuation of the Company as
a going concern is dependent upon the ability of the Company to continue executing the plan described above, generate enough revenue,
and eventually attain consistently profitable operations. Although the current global pandemic related to the coronavirus (COVID-19) has
affected our operations, particularly in supply chain, we now believe that this is expected to be an ongoing issue and our working capital
assumptions reflect this new reality. The Company cannot currently quantify the uncertainty related to the pandemic and its effects on
our customers in the coming quarters. We have analyzed our cash flow under &#x201c;stress test&#x201d; conditions and have determined that
we have sufficient liquid assets on hand to maintain operations for at least twelve months from the date of this report. A notable recent
success is the &#x201c;bonding&#x201d; secured in the amount of approximately $8 million for a major project for which the Company recently
received full &#x201c;notice to proceed&#x201d;.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company was successful in securing a loan of
$&lt;span id="xdx_901_eus-gaap--SecuredDebt_c20220331_pp0p0" title="Secured loan"&gt;1,410,270&lt;/span&gt; during the second quarter of 2020
from the Small Business Administration via the PPP/CARES Act program which further bolstered the Company&#x2019;s cash reserves. This
loan was forgiven in the first quarter of 2021 and leaves the Company essentially debt free other than the normal course of business
equipment and insurance financing. The Company has also been successful in increasing its working capital surplus after receiving
proceeds from the 2021 Offering of $4,500,000 and more recently, in the first quarter of 2022, receiving net proceeds of
approximately $&lt;span id="xdx_905_eus-gaap--ProceedsFromOtherDebt_c20220101__20220331_pp0p0" title="Net proceeds bebt"&gt;5,500,000&lt;/span&gt;
from the successful sales of common stock under the Company&#x2019;s &#x201c;shelf registration&#x201d; statement as previously
mentioned. This gives us the capital required to fund the fundamental business changes that we are executing including organization,
product alignment and market focus and maintenance of our business strategy overall. In addition, management has been taking and
continues to take actions including, but not limited to, elimination of certain costs that do not contribute to short term revenue,
and re-aligning both management and staffing with a focus on improving certain skill sets necessary to build growth and
profitability and focusing product strategy on opportunities that are likely to bear results in the relatively short term. During
2021, management took further significant actions including reorganizing our engineering and technical teams and selectively
improving organizational efficiency to effectively grow the business in concert with the influx of business won in late 2021 and
early 2022. Upon completion of the 2022 Offering, management has raised sufficient working capital to meet its needs for the next
12-months without the need to raise further capital. The Company had experienced a significant slowdown in closing new projects due
to cautious actions by current and potential clients as a result of COVID-19 but this appears to be abating as time passes. We
continue to be successful in identifying new business opportunities and are focused on maintaining a backlog of projects.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;






&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Management believes that, at this time, the conditions
in our market space with ongoing contract delays, the consequent need to procure certain materials in advance of a binding contract and
the additional time needed to execute on new contracts previously reported have put a strain on our cash reserves. However, recent events
including an approximate $5.5 million injection of funds from a sale of common stock, significant recent orders and the overall stabilization
of the business indicate that there is no longer substantial doubt for the Company to continue as a going concern for a period of twelve
months from the issuance of this report. We will continue executing the plan to grow our business and eventually achieve profitability
without the requirement to raise additional capital for existing operations for 2022 although we may do so to fund selective opportunities
that may arise. Management has extensively evaluated our requirements for the next 12 months and has determined that the Company currently
has sufficient cash to operate for at least that period.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On July 26, 2021, the Company entered a new operating
lease agreement of office and warehouse combination space of &lt;span id="xdx_90B_ecustom--AreaOfLease_usqft_c20210702__20210726_zIvQEazaxAe2" title="Area of Lease"&gt;40,000&lt;/span&gt; square feet, with the lease commencing on November 1, 2021 and ending
April 30, 2032. This new space will combine the Company&#x2019;s two separate work locations into one facility, which will allow for greater
collaboration and also accommodate a larger anticipated workforce and manufacturing facility. On November 24, 2021, the lease was amended
to commence on December 1, 2021 and end on May 31, 2032. The Company recognized a ROU asset and operating lease liability in the amount
of $&lt;span id="xdx_902_eus-gaap--OperatingLeaseLiabilityCurrent_iI_pp0p0_c20211124_zudYA8XX7dia" title="Operating lease liability"&gt;4,980,104&lt;/span&gt; at lease commencement. Rent for the first eleven months of the term will be calculated based on &lt;span id="xdx_907_ecustom--RentableSpace_usqft_c20210702__20210726_zqZKRMp3ELnb" title="Rentable Space"&gt;30,000&lt;/span&gt; rentable square feet.
The rent is subject to an annual escalation of 2.5%, beginning November 1, 2023. The Company made a security deposit payment in the amount
of $&lt;span id="xdx_902_eus-gaap--SecurityDepositLiability_c20210726_pp0p0" title="Security Deposit payment"&gt;600,000&lt;/span&gt; on July 26, 2021. The right of use asset balance at March 31, 2022, net of amortization, was $&lt;span id="xdx_903_eus-gaap--OperatingLeaseRightOfUseAsset_c20220331_pp0p0" title="Operating lease right of use asset"&gt;4,848,129&lt;/span&gt;.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As of March 31, 2022, the office and warehouse lease
is the Company&#x2019;s only lease with a term greater than twelve months. The office and warehouse lease has a remaining term of approximately
10.2 years and includes an option to extend for two renewal terms of five years each. The renewal options are not reasonably certain to
be exercised, and therefore, they are not included when determining the lease term used to establish the right-of use asset and lease
liability. The Company also has several short-term leases, primarily related to equipment. The Company made an accounting policy election
to not recognize short-term leases with terms of twelve months or less on the balance sheet and instead recognize the lease payments in
expense as incurred. The Company has also elected to account for real estate leases that contain both lease and non-lease components (such
as common area maintenance) as a single lease component.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On July 10, 2020, the Company announced that Gianni
Arcaini would retire from the positions of Chief Executive Officer and Chairman of the Board effective as of September 1, 2020 (the &#x201c;CEO
Transition&#x201d;). In order to facilitate a transition of his duties, the Company and Mr. Arcaini entered into a separation agreement
which became effective as of July 10, 2020 (the &#x201c;Separation Agreement&#x201d;). Pursuant to the Separation Agreement, Mr. Arcaini&#x2019;s
employment with the Company ended on September 1, 2020 (&#x201c;Separation Date&#x201d;) and he will receive separation payments over a
36-month period equal to his base salary plus $&lt;span id="xdx_90F_ecustom--AdditionalCompensationToBePaidInSeparationPayments_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Compensation to be paid in addition to base salary in separation payments"&gt;75,000&lt;/span&gt; as well as certain limited health and life insurance benefits. The Separation Agreement
also contains confidentiality, non-disparagement and non-solicitation covenants and a release of claims by Mr. Arcaini who continued to
serve as Chairman of the Board of Directors of the Company. The Corporate Governance and Nominating Committee did not submit Mr. Arcaini
for re-election as a director and on November 19, 2020 at the Annual Shareholders meeting a new non-Executive Chairman was appointed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In accordance with the Separation Agreement, the Company
will pay to Mr. Arcaini the total sum of $&lt;span id="xdx_900_ecustom--OnetimeChargeToBePaidOverThirtySixMonthTermOfSeparationAgreement_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="One-time charge which will be amortized in equal amounts over the 36-month term of the separation agreement"&gt;747,788&lt;/span&gt;. Notwithstanding the foregoing, the status of Mr. Arcaini as a &#x201c;Specified Employee&#x201d;
as defined in Internal Revenue Code Section 409A has the effect of delaying any payments to Mr. Arcaini under the Separation Agreement
for six months after the Separation Date. On March 1, 2021, the Company paid to Mr. Arcaini a lump-sum amount equal to the first six months
of payments, or $&lt;span id="xdx_90D_ecustom--PaymentOneOfSeparationAgreement_c20210302__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Lump sum payment owed under separation agreement"&gt;124,631&lt;/span&gt;, owed to Mr. Arcaini and the Company will continue to pay him in semi-monthly installments for 30 months thereafter,
as contemplated in Mr. Arcaini&#x2019;s Separation Agreement. The remaining balance of approximately $&lt;span id="xdx_903_eus-gaap--AccruedLiabilitiesCurrent_c20220331__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Accrued Liabilities, Current"&gt;416,000&lt;/span&gt; as of March 31, 2022 is included
in accrued expenses in the accompanying unaudited consolidated balance sheet. In addition, the Company will pay one-half of Mr. Arcaini&#x2019;s
current life insurance premiums for 36 months of approximately $&lt;span id="xdx_90E_ecustom--PaymentTwoSeparationAgreementForLifeInsurance_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Current life insurance"&gt;1,200&lt;/span&gt; per month and provide and pay for his health insurance for 36 months
following the Separation Date of approximately $450 per month. Unvested options in the amount of &lt;span id="xdx_903_ecustom--NumberOfUnvestedOptionsThatBecameExercisableAsOfSeparationDate_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pdd" title="Unvested options amount"&gt;50,358&lt;/span&gt; became exercisable and vested
in their entirety on the Separation Date valued at $95,127. The Company made payment of his attorneys&#x2019; fees for legal work associated
with the negotiation and drafting of the Separation Agreement of approximately $&lt;span id="xdx_90F_ecustom--ValueOfUnvestedOptionsThatBecameExercisableAsOfSeparationDate_c20200710__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pp0p0" title="Value of unvested options exercisable"&gt;17,000&lt;/span&gt;.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On February 26, 2021, the Company entered into a Securities
Purchase Agreement (the &#x201c;Purchase Agreement&#x201d;) with certain existing investors in the Company (the &#x201c;Purchasers&#x201d;).

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In connection with the Purchase Agreement, the Company

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s Board of Directors has designated
5,000 shares as the Series C Convertible Preferred Stock. Each share of the Series C Convertible Preferred Stock has a stated value of
$1,000. The holders of the Series C Convertible Preferred Stock, the holders of the common stock and the holders of any other class or
series of shares entitled to vote with the common stock shall vote together as one class on all matters submitted to a vote of shareholders
of the Company. Each share of Series C Convertible Preferred Stock has 172 votes (subject to adjustment); provided that in no event may
a holder of Series C Convertible Preferred Stock be entitled to vote a number of shares in excess of such holder&#x2019;s Beneficial Ownership
Limitation (as defined in the Certificate of Designation and as described below). Each share of Series C Convertible Preferred Stock is
convertible, at any time and from time to time, at the option of the holder, into that number of shares of common stock (subject to the
Beneficial Ownership Limitation) determined by dividing the stated value of such share ($1,000) by the conversion price, which is $5.50
(subject to adjustment).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company shall not effect any conversion of the
Series C Convertible Preferred Stock, and a holder shall not have the right to convert any portion of the Series C Convertible Preferred
Stock, to the extent that after giving effect to the conversion sought by the holder such holder (together with such holder&#x2019;s Attribution
Parties (as defined in the Certificate of Designation)) would beneficially own more than 4.99% (or upon election by a holder, 19.99%)
of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable
upon such conversion (the &#x201c;Beneficial Ownership Limitation&#x201d;).&lt;/p&gt;

ASC 718-10 for the three months ended March 31, 2022 and 2021, was $&lt;span id="xdx_909_eus-gaap--AllocatedShareBasedCompensationExpense_c20220101__20220331__srt--TitleOfIndividualAxis__custom--EmployeesAndDirectorsMember_z3I3Z1dpm3og" title="Stock-based compensation expense"&gt;250,577&lt;/span&gt; and $&lt;span id="xdx_902_eus-gaap--AllocatedShareBasedCompensationExpense_c20210101__20210331__srt--TitleOfIndividualAxis__custom--EmployeesAndDirectorsMember_zDvnR6osaa64" title="Stock-based compensation expense"&gt;76,301&lt;/span&gt; respectively, for stock options granted to employees
and directors. This expense is included in selling, general and administrative expenses in the unaudited consolidated statements of operations.
Stock-based compensation expense recognized during the period is based on the value of the portion of share-based payment awards that
are ultimately expected to vest during the period. At March 31, 2022, the total compensation cost for stock options not yet recognized
was $&lt;span id="xdx_90A_ecustom--TotalCompensationCostForStockOptions_iI_c20220331_z0FYWnig6Wr8" title="Total compensation cost for stock options"&gt;1,421,156&lt;/span&gt;. This cost will be recognized over the remaining vesting term of the options ranging from six months to two- and one-half

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company generates revenue from four sources: (1)
Technology Systems; (2) AI Technology which is included in the consolidated statements of operations line-item Technology systems; (3)
Technical Support; and (4) Consulting Services which is included in the unaudited consolidated statements of operations line-item Services
and consulting.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&lt;span style="text-decoration: underline"&gt;Technology Systems&lt;/span&gt;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company constructs intelligent technology systems
consisting of materials and labor under customer contracts. Revenues and related costs on technology systems revenue are recognized based
on ASC 606-10-25-27, where control of a good or service transfers over time if the entity&#x2019;s performance does not create an asset
with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date including a
profit margin or reasonable return on capital. Control is deemed to pass to the customer instantaneously as the goods are manufactured
and revenue is recognized accordingly.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In addition, the Company has adopted ASC 606-10-55-21
such that if the cost incurred is not proportionate to the progress in satisfying the performance obligation, we adjust the input method
to recognize revenue only to the extent of the cost incurred. Therefore, the Company will recognize revenue at an equal amount to the
cost of the goods to satisfy the performance obligation.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;







&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under this method, contract revenues are recognized
over the performance period of the contract in direct proportion to the costs incurred. Costs include direct material, direct labor,
subcontract labor and other allocable direct costs. All un-allocable indirect costs and corporate general and administrative costs are
also charged to the periods as incurred. Any recognized revenues that have not been billed to a customer are recorded as an asset in
&#x201c;contract assets&#x201d;. Any billings of customers more than recognized revenues are recorded as a liability in &#x201c;contract
liabilities&#x201d;. However, in the event a loss on a contract is foreseen, the Company will recognize the loss when such loss is determined.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A contract is considered complete when all costs except
insignificant items have been incurred and the installation is operating according to specifications or has been accepted by the customer.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has contracts in various stages of completion.
Such contracts require estimates to determine the appropriate cost and revenue recognition. Cost estimates are reviewed periodically on
a contract-by-contract basis throughout the life of the contract such that adjustments to the profit resulting from revisions are made
cumulative to the date of the revision. Significant management judgments and estimates, including the estimated costs to complete projects,
must be made and used in connection with the revenue recognized in the accounting period. Current estimates may be revised as additional
information becomes available.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Hlk103155204"/&gt;&lt;b&gt;Artificial Intelligence
&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Hlk103154983"/&gt;The Company has
revenue from applications that incorporate artificial intelligence (AI) in the form of predetermined algorithms which provide
important operating information to the users of our systems. The revenue generated from these applications of AI consists of a fixed
fee related to the design, development, testing and incorporation of new algorithms into the system, which is recognized as revenue
at a point in time upon acceptance, as well as an annual application maintenance fee, which revenue is recognized ratably
over the contracted maintenance term. &lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Technical Support&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span id="a_Hlk103154808"/&gt;Maintenance and technical
support services are provided on both an as-needed and extended-term basis and may include providing both parts and labor. Maintenance
and technical support provided outside of a maintenance contract are on an as-requested basis, and revenue is recognized over time as
the services are provided. Revenue for maintenance and technical support provided on an extended-term basis is recognized over time ratably
over the term of the contract.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;For sales arrangements that do not involve multiple
performance obligations such as professional services, which are of short-term duration, revenues are recognized when services are completed.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Consulting Services&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 12pt Times New Roman, Times, Serif; margin: 0"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company&#x2019;s consulting services business generates
revenues under contracts with customers from three sources: (1) Professional Services (consulting and auditing); (2) Software licensing
with optional hardware sales; and (3) Customer Service (training and maintenance support).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&#160;&lt;span style="font-size: 12pt"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company has a 401(k)-retirement savings plan (the
&#x201c;401(k) Plan&#x201d;) covering all eligible employees. The 401(k) Plan allows employees to defer a portion of their annual compensation,
and the Company may match a portion of the employees&#x2019; contributions generally after the first six months of service. During the
three months ended March 31, 2022, the Company matched 100% of the first 4% of eligible employee compensation that was contributed to
the 401(k) Plan. For the three months ended March 31, 2022, the Company recognized expense for matching cash contributions to the 401(k)
Plan totaling $&lt;span id="xdx_904_eus-gaap--DefinedBenefitPlanServiceCost_c20220101__20220331_pp0p0" title="Cash contributions"&gt;29,064&lt;/span&gt;.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On August 1, 2012, the Company entered into an
independent contractor master services agreement (the &#x201c;Services Agreement&#x201d;) with Luceon, LLC, a Florida limited
liability company, owned by our former Chief Technology Officer, David Ponevac.&#160;The Services Agreement provided that Luceon
would provide support services including management, coordination or software development services and related services to duos. In
January 2019, additional services were contracted with Luceon for TrueVue360&#x2122; primarily for software development through the
provision of 7 additional full-time contractors located in Slovakia at a cost of $&lt;span id="xdx_90C_eus-gaap--RelatedPartyCosts_c20190101__20190131_pp0p0" title="Related party cost"&gt;16,250&lt;/span&gt;
for January initially, rising to $&lt;span id="xdx_904_eus-gaap--RelatedPartyCosts_c20190201__20190228_pp0p0" title="Related party cost"&gt;25,583&lt;/span&gt;
after fully staffed, per month starting February 2019. This was in addition to the existing contract of $&lt;span id="xdx_90A_eus-gaap--RelatedPartyCosts_c20190601__20190630__srt--ProductOrServiceAxis__custom--ContractorsMember_pp0p0" title="Related party cost"&gt;7,480&lt;/span&gt;
per month for duos for 4 full-time contractors which increased to $8,231 per month in June of 2019. During 2020 efforts in reducing
cost, Luceon reduced its staff for the TrueVue360 software development team from a staff of 7 to 3 full-time employees at a cost of
$11,666 per month starting June 1, 2020. As of January 1, 2021, the Company no longer records activities in TrueVue360 and has
combined billings for a total of $&lt;span id="xdx_902_eus-gaap--AccountsPayableRelatedPartiesCurrentAndNoncurrent_c20210102_pp0p0" title="Accounts payable"&gt;20,986&lt;/span&gt;
per month. For the three months ended March 31, 2022 and 2021, the total amount expensed is zero &lt;span id="xdx_90B_eus-gaap--RelatedPartyCosts_c20220101__20220331_pp0p0" style="display: none" title="Related party cost"&gt;0&lt;/span&gt; and $&lt;span id="xdx_909_eus-gaap--RelatedPartyCosts_c20210101__20210331_pp0p0" title="Related party cost"&gt;62,958&lt;/span&gt;, respectively. The
Company had no open accounts payable with Luceon at March 31, 2022. On May 14, 2021, the Company formally ended its relationship
with Luceon in concert with the resignation of our Chief Technology Officer and as such there is no longer a related party
relationship.&lt;/p&gt;
