(&ldquo;Shares&rdquo;) of our common stock, par value $0.001 per share, pursuant to this prospectus supplement and the accompanying base
prospectus. The public offering price for Shares of our common stock is $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; per share.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">We are also offering to
each purchaser of shares that would otherwise result in the purchaser&rsquo;s beneficial ownership exceeding 4.99% of our outstanding
common stock immediately following the consummation of this offering, the opportunity to purchase pre-funded warrants (the &ldquo;Pre-Funded
Warrants&rdquo;) in lieu of shares of common stock. Subject to limited exceptions, a holder of Pre-Funded Warrants will not have the right
to exercise any portion of its Pre-Funded Warrants if the holder, together with its affiliates, would beneficially own in excess of 4.99%
(or, at the election of the holder, such limit may be increased to up to 9.99%) of the number of shares of common stock outstanding immediately
after giving effect to such exercise. Each Pre-Funded Warrant is exercisable for one share of our common stock. The purchase price of
each Pre-Funded Warrant is equal to the price at which a share of common stock is sold in this offering, minus $0.001, and the exercise
price of each Pre-Funded Warrant is $0.001 per share. The Pre-Funded Warrants will be immediately exercisable and may be exercised at
any time until all of the Pre-Funded Warrants are exercised in full. The Pre-Funded Warrants and the shares of common stock issuable upon
the exercise thereof are being registered on the registration statement of which this prospectus supplement is a part.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">Our common stock is listed
on The Nasdaq Capital Market under the symbol &ldquo;DUOT.&rdquo; On July 29, 2025, the last reported sales price of our common stock
on The Nasdaq Capital Market was $7.42 per share. There is no established trading market for the Pre-Funded Warrants, and we do not expect
a trading market to develop. We do not intend to list the Pre-Funded Warrants on any securities exchange or nationally recognized trading
system. Without a trading market, the liquidity of the Pre-Funded Warrants will be extremely limited.</P>

REGARDING FORWARD-LOOKING STATEMENTS</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">This prospectus supplement
and any accompanying prospectus, including the documents that we incorporate by reference, contain forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended (the &ldquo;Securities Act&rdquo;), and Section 21E of the Securities
Exchange Act of 1934, as amended (the &quot;Exchange Act&quot;). These forward-looking statements are intended to be covered by the safe
harbor for forward-looking statements provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements give
our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly
to historical or current facts. Forward-looking statements involve risks and uncertainties and include statements regarding, among other
things, our projected revenue growth and profitability, our growth strategies and opportunity, anticipated trends in our market and our
anticipated needs for working capital. They are generally identifiable by use of the words &ldquo;may,&rdquo; &ldquo;will,&rdquo; &ldquo;should,&rdquo;
&ldquo;anticipate,&rdquo; &ldquo;estimate,&rdquo; &ldquo;plans,&rdquo; &ldquo;potential,&rdquo; &ldquo;projects,&rdquo; &ldquo;continuing,&rdquo;
&ldquo;ongoing,&rdquo; &ldquo;expects,&rdquo; &ldquo;management believes,&rdquo; &ldquo;we believe,&rdquo; &ldquo;we intend&rdquo; or
the negative of these words or other variations on these words or comparable terminology. In particular, these include statements relating
to future actions, prospective products, market acceptance, future performance or results of current and anticipated products, sales efforts,
expenses, and the outcome of contingencies such as legal proceedings and financial results. Any forward-looking statements are qualified
in their entirety by reference to the factors discussed throughout this prospectus supplement.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">Examples of forward-looking
statements include, but are not limited to, our expectations regarding our business strategy, business prospects, operating results, operating
expenses, working capital, liquidity and capital expenditure requirements. Important assumptions relating to the forward-looking statements
include, among others, assumptions regarding demand for our products, the cost, terms and availability of components, pricing levels,
the timing and cost of capital expenditures, competitive conditions and general economic conditions. These statements are based on our
management&rsquo;s current expectations, beliefs and assumptions concerning future events affecting us, which in turn are based on currently
available information. These assumptions could prove inaccurate. They are subject to risks and uncertainties known and unknown that could
cause actual results and developments to differ materially from those expressed or implied in such statements. Although we believe that
the estimates and projections reflected in the forward-looking statements are reasonable, our expectations may prove to be incorrect.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">You should read this prospectus
supplement, the accompanying prospectus and the documents that we incorporate by reference herein and therein and have filed as exhibits
to the registration statement, of which this prospectus supplement is part, completely and with the understanding that our actual future
results may be materially different from what we expect. You should assume that the information appearing in this prospectus supplement
and any accompanying prospectus is accurate as of the date on the front cover of this prospectus supplement. Because the risk factors
referred to above, as well as the risk factors included in this prospectus supplement, the accompanying prospectus and those incorporated
herein by reference, could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements
made by us or on our behalf, you should not place undue reliance on any forward-looking statements. Further, any forward-looking statement
speaks only as of the date on which it is made, and except as may be required under applicable securities laws, we undertake no obligation
to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect
the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict which factors will
arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors,
may cause actual results to differ materially from those contained in any forward-looking statements. We qualify all of the information
presented in this prospectus supplement and the accompanying prospectus and the documents that we incorporate by reference herein and
therein, and particularly our forward-looking statements, by these cautionary statements.</P>

prospectus supplement and the accompanying prospectus carefully, including the &ldquo;Risk Factors&rdquo; section contained in this prospectus

<P STYLE="font: bold 10pt Times New Roman, Times, Serif; margin: 0 0 12pt">Our Corporate History</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">Information Systems Associates,
Inc. (&ldquo;ISA&rdquo;) was incorporated in Florida on May 31, 1994. Our original business operations consisted of consulting services
for asset management of large corporate data centers and the development and licensing of information technology (&ldquo;IT&rdquo;) asset
management software. In late 2014, ISA entered negotiations with Duos Technologies, Inc. (&ldquo;duostech&trade;&rdquo;) for the purposes
of executing a merger between the two organizations (also known as a &ldquo;reverse triangular merger&rdquo;). Incorporated under the
laws of Florida on November 30, 1990, duostech&trade; operated in various industry segments, specializing in the design, development and
deployment of proprietary technology applications and turn-key engineered systems. This transaction was completed on April 1, 2015, whereby
duostech&trade; became a wholly owned subsidiary of ISA. After the merger was completed, ISA changed its corporate name to Duos Technologies
Group, Inc. (&ldquo;Duos&rdquo; or the &ldquo;Company&rdquo;). During 2024, the Company began a major expansion into new markets, leveraging
the developments previously undertaken and the experience of its management team. Still headquartered in Jacksonville, Florida, Duos now
manages three, wholly owned subsidiaries, duostech&trade;, Duos Edge AI Inc., (&ldquo;Duos Edge&rdquo;) and Duos Energy Corporation (&ldquo;Duos
Energy&rdquo;). The proceeds of this offering are expected to further our Duos Edge business. In its current operations it now employs
approximately 100 people in management, operations, engineering, software development, customer support and project implementation and
management across three major market segments including rail technology deployment, Data Center co-location facilities and behind the
meter electrical power provision. Duos also continues to operate as a technology company which designs, develops, deploys and operates
intelligent technology solutions with a focus on software applications and artificial intelligence (&ldquo;AI&rdquo;) in addition to large
project, consulting, implementation and asset management. The Company has a strong and growing portfolio of intellectual property including
significant patent awards in the areas of railcar scanning technology for the identification of defects.</P>

<P STYLE="font: bold 10pt Times New Roman, Times, Serif; margin: 0 0 12pt">Overview</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">The Company, operating
under its brand name&nbsp;<B>duostech</B>, develops and deploys technology systems with focus on inspecting and evaluating moving vehicles.
Its technology focus is within the Vision Technology market sector and, more specifically, the Machine Vision subsector. Machine Vision
companies provide imaging-based automatic inspection and analysis for process control for industry with potential expansion into other
markets. Duos has developed key technologies over the past several years in software, industry specific hardware and artificial intelligence
and has demonstrated industrial strength usability of its systems supporting rail, logistics and intermodal businesses that streamline
operations, improve safety and reduce costs. Our team includes engineering subject matter expertise in hardware, software, and information
technology as well as industry specific applications of artificial intelligence also referred to as Expert Artificial Intelligence. We
also have specific industry experts in the rail industry on staff and as consultants.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">In 2024, the Company&rsquo;s
management team determined that it would be in the best interests of the Company and its shareholders to leverage the skills and expertise
that have been built up since 2021 to expand into complimentary and naturally adjacent markets. In addition, the Company elected to develop
new offerings based on its existing technology and formed a new subsidiary in July 2024, Duos Edge AI. The objective of this new subsidiary
is to market a special part of the Railcar Inspection Portal (&ldquo;RIP&rdquo;) for the provision of high-speed and function processing
of data and applications with a focus on reducing latency in response times to end-users. Duos has many years of experience via its expert
staff in bringing these types of capabilities to remote locations, also known as &ldquo;the edge&rdquo;. Edge processing can be an extremely
efficient and lower cost alternative to traditional data centers. The strategy for Duos Edge is to serve rural communities, also known
as Tier 3 and 4 markets, and install Edge data centers in these locations thereby providing access to high-speed communications and advanced
processing capabilities as a substitute for solutions where large amounts of data are &ldquo;backhauled&rdquo; using &ldquo;the Cloud&rdquo;.
Duos developed these capabilities as an adjunct to its RIP offerings due to the need for fast results (less than 60 seconds) in identifying
defects and maintenance issues on moving railcars. The purpose of this offering is to further the Duos Edge business with the expected proceeds of this offering being
used to execute on our customer backlog and advance to Stage 2 of our Edge Data Center strategy, which is the development and deployment
of more than 65 edge data centers.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">As Duos&rsquo; initial
offering, the RIP provides both freight and transit railroad customers and select government agencies the ability to conduct fully remote
railcar inspections of trains while they are moving at full speed. The RIP utilizes a variety of sophisticated optical, laser and speed
sensors to scan each passing railcar to create a high-resolution image-set of the top, sides and undercarriage. These images are then
processed with our edge data center using artificial intelligence (AI) algorithms to identify safety and security defects on each railcar.
The algorithms are developed in conjunction with industrial application experts, in this case resident Railcar Mechanical Engineers, to
provide specific guidance in the analysis (&ldquo;human in the loop&rdquo;). Within seconds of the railcar passing through the RIP, a
detailed report is sent to the customer where they are able to take action on identified issues. This solution has the potential to transform
the railroad industry immediately increasing safety, improving efficiency and reducing costs. The Company has already deployed this system
with several Class 1 railroads and anticipates an increased demand from transit and other railroad customers along with selected government
agencies that operate and/or manage rail traffic. The Company has deployed RIPs in Canada, Mexico and the United States and anticipates
expanding this solution into Europe, Asia and the Middle East in coming years.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">Duos believes it has been
successful in patenting much of its technology and specifically for the rail industry offerings. Key patents developed by or for the Company
include:</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">We believe that these three
recent patents, in conjunction with eight other patents, put Duos in a strong position for this type of scanning technology (also known
as &ldquo;Wayside Technology&rdquo;) and the Company expects to both deploy systems and, where appropriate, license to users or manufacturers.
The Company has previously notified a third party of the existence of these patents. It is not expected that the proceeds of this offering
will be used to further the Company&rsquo;s rail industry offerings.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">The Company has also developed
the Automated Logistics Information System (ALIS) which can automate gatehouse operations where transport trucks enter and exit large
logistics and intermodal facilities. This solution incorporates a similar set of sensors, data processing and artificial intelligence
to streamline the customer&rsquo;s logistics transactions and tracking and can also automate the security and safety inspection if called
for. The Company has previously deployed this system with one large North American retailer. While Duos originally anticipated increased
demand from other large retailers, railroad intermodal operators and select government agencies that manage logistics and border crossing
points, the Company has been resource constrained to effectively market this offering. However, the Company continues to perform research
and development in evaluating other solutions for moving vehicles including aircraft, which could provide similar benefits in terms of
safety and efficiency for required inspections as part of an operations process. The Company will continue to evaluate its resource commitments
in future years in conjunction with the expected growth in revenues and cash flow to support additional investments in these areas.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">Also in late 2024, Duos
formed a third subsidiary, Duos Energy Corporation (&ldquo;Duos Energy&rdquo;) with the express purpose of providing consulting services
and solutions for the rapidly growing demand for electrical power outside of traditional utilities. As an outgrowth of its new Edge Data
Center subsidiary, and the current expert staff on-hand, Duos has engaged with multiple third parties to act in a consulting and asset
management capacity whereby Duos staff will be engaged directly to supply this type of power solutions for multiple uses including for
large data centers supporting AI &ldquo;hyperscalers&rdquo;. In late 2024, Duos also engaged with Fortress Investment Group (&ldquo;FIG&rdquo;)
to assist in FIG&rsquo;s purchase of approximately 850 Mega Watts of electrical generation capacity (consisting of 30 mobile gas turbine
generators) and associated equipment to support their installation and operation (&ldquo;balance of plant&rdquo;), certain trademarks
and domain names and certain contracts. In late November 2024, Sawgrass Buyer, LLC (&ldquo;Sawgrass&rdquo;), an entity formed and owned
by FIG, executed an asset purchase agreement with Atlas Corporation, APR Energy Holdings Limited and a number of its wholly-owned affiliates
(collectively &ldquo;APR&rdquo;). From 2018 to 2020, Chuck Ferry, our CEO, was formerly the CEO of APR. The transaction closed on December
31, 2024. At closing, Sawgrass entered into an Asset Management Agreement (&ldquo;AMA&rdquo;) with Duos under which a substantial portion
of Duos staff and some members of the management team (including Mr. Ferry), would oversee operations of Sawgrass. The AMA term is up
to two years and is expected to generate approximately $42 million in revenue for Duos over that period. At closing, Duos also took a
5% ownership stake in Sawgrass APR Holdings LLC, the ultimate parent company of Sawgrass. Subsequent to closing, Sawgrass changed its
name to New APR Energy, LLC (&ldquo;New APR&rdquo;).</P>

AMA, Duos staff is conducting all operations for commercial engagement, planning and project management, installation and operations of
the New APR assets. The new entity shares certain management functions with Duos including the CEO, COO, Chief Commercial Officer and
General Counsel and other services provided by Duos in a combination of direct staffing with specific experience in the power generation
industry and other functions as necessary via a &ldquo;shared services&rdquo; agreement. New APR over time will develop its own accounting
and administrative functions and have its own President and Chief Financial Officer, though, while that is in the early stages, certain
accounting staff is being supplied via the shared services agreement. It is expected that there will be a strong correlation between the
two companies, particularly in the areas of Data Center power generation and business development, and Duos is expected to participate
in these opportunities in addition to the anticipated revenues from the AMA.</P>

securities involves a high degree of risk</I></B>. In addition to the risks and investment considerations discussed elsewhere in this
prospectus supplement or any document incorporated by reference herein, the following factors should be carefully considered by anyone
purchasing the securities offered by this prospectus supplement. The risks and uncertainties described below are not the only ones we
face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations.
We also update risk factors from time to time in our periodic reports on Forms 10-K, 10-Q and 8-K which will be incorporated by reference
in this prospectus supplement. See &ldquo;<I>Where You Can Find More Information</I>&rdquo; and &ldquo;<I>Incorporation of Certain Information
by Reference</I>.&rdquo; If any of the following risks actually occur, our business could be harmed. In such case, the trading price of
our common stock could decline and investors could lose all or a part of their investment. This prospectus supplement also contains forward-looking
statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking
statements as a result of certain factors, including the risks we face as described below and elsewhere in this prospectus supplement.
See &ldquo;<I>Cautionary Note Regarding Forward Looking Statements</I>.&rdquo;</P>

<P STYLE="font: bold 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: center">Risks Relating to this Offering</P>

net proceeds from this offering.</I></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">We cannot specify with
certainty the particular uses of the net proceeds we will receive from this offering, and these uses may vary from our current plans.
Our management will have broad discretion in the application of the net proceeds, including for any of the purposes described in &ldquo;<I>Use
of Proceeds</I>.&rdquo; Accordingly, you will have to rely upon the judgment of our management with respect to the use of the proceeds.
Our management may spend a portion or all of the net proceeds from this offering in ways that holders of our common stock may not desire
or that may not yield a significant return or any return at all. The failure by our management to apply these funds effectively could
harm our business. Pending their use, we may also invest the net proceeds from this offering in a manner that does not produce income
or that loses value.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt"><B><I>If you purchase the common stock being offered in this offering,
you will experience immediate dilution as a result of this offering.</I></B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">Since the price per share
of our common stock and value of our Pre-Funded Warrants being offered are substantially higher than the net tangible book value per share
of our common stock, you will suffer immediate and substantial dilution in the net tangible book value of the common stock you purchase
in this offering. After giving effect to the sale by us of &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; shares of our common
stock at the offering price of $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; per share of common stock and Pre-Funded
Warrants (rounded for purposes of the Pre-Funded Warrants), if you purchase shares of common stock in this offering, you will suffer immediate
and substantial dilution of approximately $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; per share in the net tangible book value of
the common stock and Pre-Funded Warrants. The foregoing assumes that none of the Pre-Funded Warrants or Underwriter Warrants are exercised
in this offering. Any exercise of outstanding stock options, preferred stock, warrants or other equity awards will result in further dilution.
See the section entitled &ldquo;<I>Dilution</I>&rdquo; in this prospectus supplement for a more detailed discussion of the dilution you
will incur if you purchase common stock in this offering.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt"><B><I>Holders of Pre-Funded Warrants purchased in this offering

Warrants acquire shares of our common stock upon exercise of the Pre-Funded Warrants, holders of Pre-Funded Warrants will have no rights
with respect to the shares of our common stock underlying such Pre-Funded Warrants. Upon exercise of the Pre-Funded Warrants, the holders
will be entitled to exercise the rights of a holder of common stock only as to matters for which the record date occurs after the exercise
date.</P>

its affiliates and other attribution parties) may not exercise any portion of a Pre-Funded Warrant to the extent that immediately prior
to or after giving effect to such exercise the holder would own more than 4.99% of our outstanding common stock immediately after exercise,
which percentage may be changed at the holder&rsquo;s election to a higher or lower percentage not in excess of 9.99%. As a result, the
holder may not be able to exercise its Pre-Funded Warrants for shares of our common stock at a time when it would be financially beneficial
for the holder to do so. In such a circumstance, the holder could seek to sell its Pre-Funded Warrants to realize value, but the holder
may be unable to do so in the absence of an established trading market and due to applicable transfer restrictions.</P>

the effect, if any, that future sales and issuances of shares of our common stock will have on the market price of our common stock. Sales
of substantial amounts of our common stock, or the perception that such sales could occur, may adversely affect prevailing market prices
for our common stock. In addition, these sales may be dilutive to existing stockholders.</P>

sold in the offering will be freely tradable without restriction or further registration under the Securities Act. As a result, a substantial
number of our shares of common stock may be sold in the public market following this offering, which may cause the market price of our
common stock to decline. If there are more shares of common stock offered for sale than buyers are willing to purchase, then the market
price of our common stock may decline to a market price at which buyers are willing to purchase the offered shares of common stock and
sellers remain willing to sell the shares of common stock.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">As of July 28, 2025, there
were outstanding stock options to purchase 485,125 shares of our common stock at a weighted-average exercise price of $5.30 per share,
and shares of preferred stock convertible into 5,122,273 shares of our common stock at a weighted-average conversion price of $2.63 per
share. Our outstanding options, and preferred stock could adversely affect our ability to obtain future financing or engage in certain
mergers or other transactions, since the holders of options and preferred stock can be expected to exercise or convert them at a time
when we may be able to obtain additional capital through a new offering of securities on terms more favorable to us than the terms of
outstanding options, preferred stock. The issuance of shares upon the exercise or conversion of outstanding options or preferred stock
will also dilute the ownership interests of our existing stockholders.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify"><B><I>The rights of the holders of common stock
may be impaired by the potential issuance of preferred stock.</I></B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">Our board of directors
has the right, without stockholder approval, to issue preferred stock with voting, dividend, conversion, liquidation or other rights which
could adversely affect the voting power and equity interest of the holders of common stock, which could be issued with the right to more
than one vote per share, and could be utilized as a method of discouraging, delaying or preventing a change of control. The possible negative
impact on takeover attempts could adversely affect the price of our common stock. Although we have no present intention to issue any shares
of preferred stock or to create any new series of preferred stock, we may issue such shares in the future.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify"><B><I>Because we do not intend to pay dividends

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">We have never declared
or paid any cash dividends on our shares of common stock. We currently intend to retain all future earnings, if any, for use in the operations
and expansion of the business. As a result, we do not anticipate paying cash dividends in the foreseeable future. Any future determination
as to the declaration and payment of cash dividends will be at the discretion of our Board of Directors and will depend on factors the
Board of Directors deems relevant, including, among others, our results of operations, financial condition and cash requirements, business
prospects, and the terms of our financing arrangements, if any. Accordingly, realization of a gain on stockholders&rsquo; investments
will depend on the appreciation of the price of our common stock. There is no guarantee that our common stock will appreciate in value.</P>

liabilities) by the number of shares of our common stock issued and outstanding.</P>

or $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; per share. This represents an immediate increase in net tangible book value of approximately
$&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; per share to our existing stockholders, and an immediate dilution of $&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

certain terms and provisions of the Pre-Funded Warrants that are being offered hereby is not complete and is subject to, and qualified
in its entirety by, the provisions of the Pre-Funded Warrant, the form of which will be filed as an exhibit to a Current Report on Form
8-K in connection with this offering and incorporated by reference into the registration statement of which this prospectus supplement
forms a part. Prospective investors should carefully review the terms and provisions of the form of Pre-Funded Warrant for a complete
description of the terms and conditions of the Pre-Funded Warrants.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in"><B><I>Duration and exercise
price. </I></B>Each Pre-Funded Warrant offered hereby will have an initial exercise price per share equal to $0.001. The exercise price
and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock
splits, reorganizations or similar events affecting our common stock and the exercise price.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in"><B><I>Exercisability. </I></B>The
Pre-Funded Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise
notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of
a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of such holder&rsquo;s Pre-Funded
Warrant to the extent that the holder would own more than 4.99% of the outstanding shares of common stock immediately after exercise,
except that upon at least 61 days&rsquo; written prior notice from the holder to us, the holder may increase or decrease the amount of
ownership of outstanding shares of common stock after exercising the holder&rsquo;s Pre-Funded Warrants up to 9.99% of the number of shares
of common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance
with the terms of the Pre-Funded Warrants. No fractional shares of common stock will be issued in connection with the exercise of a Pre-Funded
Warrant. In lieu of fractional shares, we will either pay the holder an amount in cash equal to the fractional amount multiplied by the
exercise price or round up to the next whole share.</P>

</I></B>If at the time of exercise, there is no effective registration statement registering the issuance of the shares upon exercise
of the Pre-Funded Warrants, in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of
the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of
shares of common stock determined according to a formula set forth in the Pre-Funded Warrants.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in"><B><I>Fundamental transactions.
</I></B>In the event of any fundamental transaction, as described in the Pre-Funded Warrants and generally including any merger with or
into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our shares
of common stock, then upon any subsequent exercise of a Pre-Funded Warrant, the holder will have the right to receive as alternative consideration,
for each share of common stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental
transaction, the number of shares of common stock of the successor or acquiring corporation or of our company, if it is the surviving
corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of
common stock for which the Pre-Funded Warrant is exercisable immediately prior to such event.</P>

A naked short position occurs if the underwriter sells more shares than could be covered by the over-allotment option. This position can only be closed out by buying shares in the open market.&nbsp;A naked short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.</TD></TR>

develops and deploys technology systems with focus on inspecting and evaluating moving vehicles. Its technology focus is within the Vision
Technology market sector and, more specifically, the Machine Vision subsector. Machine Vision companies provide imaging-based automatic
inspection and analysis for process control for industry with potential expansion into other markets. Duos has developed key technologies
over the past several years in software, industry specific hardware and artificial intelligence and has demonstrated industrial strength
usability of its systems supporting rail, logistics and intermodal businesses that streamline operations, improve safety and reduce costs.
Our team includes engineering subject matter expertise in hardware, software, and information technology as well as industry specific
applications of artificial intelligence also referred to as Expert Artificial Intelligence. We also have specific industry experts on

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Duos is currently developing industry solutions for
its target markets which will address rail, trucking, aviation and other vehicle-based processes. Duos&rsquo; initial offering, the Railcar
Inspection Portal (RIP), provides both freight and transit railroad customers and select government agencies the ability to conduct fully
automated railcar inspections of trains while they are moving at full speed. The RIP utilizes a variety of sophisticated optical, laser
and speed sensors to scan each passing railcar to create a high-resolution image-set of the top, sides and undercarriage. These images
are then processed with our edge data center using artificial intelligence (AI) algorithms to identify safety and security defects on
each railcar. The algorithms are developed in conjunction with industrial application experts, in this case resident Railcar Mechanical
Engineers, to provide specific guidance in the analysis (&ldquo;human in the loop&rdquo;). Within minutes of the railcar passing through
the RIP, a detailed report is sent to the customer where they are able to action identified issues. This solution has the potential to
transform the railroad industry by increasing safety, improving efficiency and reducing costs. The Company has already deployed this system
with several Class 1 railroads and anticipates an increased demand from transit and other railroad customers along with selected government
agencies that operate and/or manage rail traffic. The Company has deployed RIPs in Canada, Mexico and the United States and anticipates
expanding this solution into Europe, Asia and the Middle East in coming years.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&nbsp;</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 gatehouse operations where transport trucks enter and exit large logistics and intermodal facilities.
This solution incorporates a similar set of sensors, data processing and artificial intelligence to streamline the customer&rsquo;s logistics
transactions and tracking and can also automate the security and safety inspection if called for. The Company has already deployed this
system with one large North American retailer and anticipates increased demand from other large retailers, railroad intermodal operators
and select government agencies that manage logistics and border crossing points. The Company is evaluating other solutions for moving
vehicles including aircraft, which could provide similar benefits in terms of safety and efficiency for required inspections as part of
an operations process.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In 2021, the Company ended support of its IT Asset
Management (ITAM) solution which cataloged results for data center asset inventory and audit services. We are currently evaluating using
our current operations experience within &ldquo;edge data centers&rdquo; (as deployed for our Railcar Inspection Portal) to drive additional
revenues within other markets requiring this type of solution although no specific offering has been developed at this time.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Federal regulations require each railcar/train to
be inspected for mechanical defects prior to leaving a rail yard. Founded in 1934, the Association of American Railroads (AAR) is responsible
for setting the standards for the safety and productivity of the U.S./North American freight rail industry, and by extension, has established
the inspection parameters for the rail industry&rsquo;s rolling stock. Also known as the &ldquo;Why Made&rdquo; codes, the AAR established
approximately 110 inspection points under its guidelines for mechanical inspections.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Under current practice, inspections are conducted
manually, a very labor intensive and inefficient process that only covers a select number of inspection points and can take several hours
per train. We believe our Railcar Inspection Portal has the potential to reduce this inspection to minutes while the train is moving at
speed, improving safety, reducing dwell time and optimizing maintenance.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Our system combines high-definition image and data
capture technologies with our AI-based analytics applications that are typically installed on active tracks located between two rail yards.
We inspect railcars traveling through our inspection portal at speeds of up to 70 mph and report mechanical anomalies detected by our
system to the inbound train yard, well ahead of the train entering the yard.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Currently, three Class 1 railroads and several transit
and international railroads use our rip&reg; technology with one of those railroads broadly deploying the technology across its network.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><B>&nbsp;</B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company continues to expand its detection capabilities
through the development and integration of additional sensor technologies to include laser, infrared, thermal, sound and x-ray to process
AI-based analytics of inspection points. Currently the Company has a high-reliability catalog of over 35 artificial intelligence algorithms
which can be integrated into the RIP to enhance mechanical anomalies detections. These detections support railroads in the active maintenance
and overall safety of their railcar fleet and networks.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">We believe the opportunity for our Railcar Inspection
Portal business is substantial and continues to be our number one priority. We are currently engaged with the RIP solution with three
of seven Class 1 railroad operators with 13 systems already deployed across the North American rail network. Because of our early leadership
position, we have been able to accumulate experience and intellectual property that we believe would be time consuming and expensive for
a new competitor to replicate. Furthermore, we believe we have the ability to upgrade and scale our solutions with additional technologies
in the future. We believe that the current market for our technologies is substantial. At the same time, we recognize that the technology
life cycle is fast and evolving. Potential competitors could move into this sector, and it is possible that some Class 1 railroads could
develop their own solutions that limit our total addressable market.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In late 2022, the Company announced it will pursue
a subscription platform for the RIPs. Under this new model, the Company will build, own and operate its RIP product and offer the data
access for each portal to potential customers. This expansion of the RIP offering would potentially open up the addressable market to
other railroads, railcar owners, and car lessors. This shift increases the pool of potential customers by lowering the entry point for
the RIP and would reshape the Company&rsquo;s working capital needs to invest in the construction of a RIP ahead of customer revenue inflows.
The Company continues to explore this expansion on the long-term effects it may have on future cash flows.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Our Automated Logistics Information System (ALIS)
also represents an opportunity to expand into a mature market that we believe has a significant technology gap.&nbsp; While most facilities,
such as distribution centers, that process commercial trucks in and out have sophisticated software management applications for logistics
control, they have most often not implemented an advanced gatehouse automation solution. Historically, this category was referred to as
&ldquo;Automated Gate Systems&rdquo; or AGS.&nbsp; The purpose of AGS technology is to streamline entry in to and exit out of facilities.&nbsp;
The marketplace for this was mostly seaports and intermodal transfer facilities and was relatively expensive technology to deploy.&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Our organic growth strategy is to continue our focus
and prioritization in the rail, logistics and intermodal market space. In this regard, the Company has made significant changes in the
senior management team to include a new Chief Executive Officer, who joined the Company in September 2020 and has years of experience
successfully leading start-up and turn-around companies. In addition, a key account executive from one of duos&rsquo; competitors has
joined the executive team during late 2022 as the Senior Vice President of Sales &amp; Marketing to support the continued revenue growth
of the business and brings with him over 20 years of sales experience focused in the rail market. In 2021, the Company also hired a new
Chief Technology Officer bringing 25 years of experience in designing and delivering value driven technologies. Our new CTO has already
led the team through instrumental changes to its approach to software and artificial intelligence development. The team also saw a change
in CFO in late 2022 with the new CFO bringing significant experience in growth for asset-intensive businesses which aligns with the subscription
format the Company will expand into.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">The new leadership team&rsquo;s
focus is to improve operational and technical execution which will in turn enable the commercial side of the business to expand RIP and
ALIS delivery into existing and new customers. Even though supply chain issues are expected to continue through 2023, the Company&rsquo;s
primary customers have indicated readiness to order more equipment and services based upon the Company&rsquo;s current performance and
the new subscription offerings expands the universe of potential customers.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">Additionally, the CEO has
directed that the Company make continual engineering and software upgrades to the RIP to meet anticipated Federal Railroad Association
(FRA) and Association of American Railroad (AAR) standards.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company designs and develops technology solutions
using a combination of in-house fabrication, commercial off-the-shelf technology, and outsourced manufacturing. On-site installations
are performed using a combination of in-house project managers and engineers and using third-party sub-contractors as needed. Throughout
the process of design, develop, deploy and operate, the Company maintains responsibility for all aspects. Our internal manufacturing operations
consist primarily of materials procurement, assembly, testing and quality control by our engineers. If not manufactured internally, we
use third-party manufacturing partners to produce our hardware related components and hardware products and we most often complete final
assembly, testing and quality control processes for these components and products. Our manufacturing processes are based on standardization
of components across product types, centralization of assembly and distribution centers, and a &ldquo;build-to-order&rdquo; methodology
in which products generally are built only after customers have placed firm orders. For most of our hardware products, we have existing
alternate sources of supply.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For 2023 and possibly beyond, we expect to face significant
challenges with macro-economic impacts, specifically inflation and supply chain disruption. Although these started to be identified in
late 2021, we believe they continue to manifest themselves in ways that could challenge our business growth in the future. Specifically,
the ability to source key components and certain implementation services will dictate just how quickly the Company can meet desired installation
deadlines. In the industries in which we operate, the time from concept to contract can be substantial. Although we are now adapting to
these challenges, previous bids that have been submitted could be challenging to execute within the financial framework and execution
times originally envisaged. We continue to have dialogue with our customers regarding potential price increases and implementation delays,
but we may suffer some economic impacts as a result of this. Revenue recognition could be delayed as a result of these factors and profitability
could be impacted due to higher costs for materials and other services. The Company will continue to monitor the situation and update
shareholders as the situation unfolds.</P>

teams design and develop all systems and software applications with a combination of full-time in-house software engineers and outside
contractors. Internal development allows us to maintain technical control over the design and development of our products. Rapid technological
advances in hardware and software development, evolving standards in computer hardware and software technology, and changing customer
requirements characterize the markets in which we compete. We plan to continue to dedicate significant resources to research and development
efforts, including software development, to maintain and improve our current product and services offerings.</P>

by regulations related to the safe and effective transportation of goods, primarily by rail, but in future scenarios by air, road and
sea. While changes in the regulatory environment could impact the Company in future years, we believe any changes will be overall positive
for the Company. We continuously review potential changes in the regulatory environment and maintain contact with key personnel at certain
agencies including the Federal Railroad Administration (FRA), the Transportation Safety Agency (TSA) as well as the DHS previously mentioned.
We expect to develop similar relationships with governmental agencies in target markets both in the US and internationally. At this time,
we believe our offerings are complementary to the current and evolving standards and that we will adapt to any new regulations as they
are promulgated.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Information Systems Associates, Inc. (&ldquo;ISA&rdquo;)
was incorporated in Florida on May 31, 1994. Our original business operations consisted of consulting services for asset management of
large corporate data centers and the development and licensing of information technology (&ldquo;IT&rdquo;) asset management software.
In late 2014, ISA entered negotiations with Duos Technologies, Inc. (&ldquo;duostech&trade;&rdquo;) for the purposes of executing a merger
between the two organizations (also known as a &ldquo;reverse triangular merger&rdquo;). Incorporated under the laws of Florida on November
30, 1990, duostech&trade; operated in various industry segments, specializing in the design, development and deployment of proprietary
technology applications and turn-key engineered systems. This transaction was completed on April 1, 2015, whereby duostech&trade; became
a wholly owned subsidiary of ISA. After the merger was completed, ISA changed its corporate name to Duos Technologies Group, Inc. The
Company, based in Jacksonville, Florida, oversees its wholly owned subsidiary, duostech&trade; and employs approximately 75 people and
is a technology company which designs, develops, deploys and operates intelligent technology solutions with a focus on software applications
and artificial intelligence (&ldquo;AI&rdquo;). The Company has a strong portfolio of intellectual property. The Company&rsquo;s headquarters
are located at 7660 Centurion Parkway, Suite 100, Jacksonville, Florida 32256 and main telephone number is (904) 296-2807.</P>

preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of
redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of any series,

to render more difficult or to discourage an attempt to obtain control of the Company by means of a tender offer, proxy contest, merger

rights, liquidation preference or both, may have full or limited voting rights and may be convertible into shares of common stock. As
a result, the issuance of shares of preferred stock, or the issuance of rights to purchase shares of preferred stock, may discourage an
unsolicited acquisition proposal or bids for our common stock or may otherwise adversely affect the market price of our common stock or
any existing preferred stock.</P>

prospectus, we will provide a prospectus supplement or supplements that will describe the method of distribution and set forth the terms
and conditions of the offering of such securities, including the offering price of the securities and the proceeds to us, if applicable.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Offers to purchase the securities being offered by
this prospectus may be solicited directly. Agents may also be designated to solicit offers to purchase the securities from time to time.
Any agent involved in the offer or sale of our securities will be identified in a prospectus supplement.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">If a dealer is utilized in the sale of the securities
being offered by this prospectus, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to
the public at varying prices to be determined by the dealer at the time of resale.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">If an underwriter is utilized in the sale of the securities
being offered by this prospectus, an underwriting agreement will be executed with the underwriter at the time of sale and the name of
any underwriter will be provided in the prospectus supplement that the underwriter will use to make resales of the securities to the public.
In connection with the sale of the securities, we or the purchasers of securities for whom the underwriter may act as agent, may compensate
the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and
those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from
the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best
efforts basis and a dealer will purchase securities as a principal, and may then resell the securities at varying prices to be determined
by the dealer.</P>

agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating
dealers will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of
the securities may be deemed to be underwriters within the meaning of the Securities Act of 1933, as amended, and any discounts and commissions
received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions.
We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the
Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain
expenses.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Any common stock will be listed on the Nasdaq Capital
Market, but any other securities may or may not be listed on a national securities exchange. To facilitate the offering of securities,
certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the
securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the
offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions
by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize
or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby
selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection
with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at
a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.</P>
