Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP. We consolidated our wholly-owned subsidiaries and eliminated all significant intercompany balances and transactions. We have also prepared the accompanying unaudited consolidated financial statements in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X and, consequently, they do not include all of the annual disclosures required by GAAP. Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2019 for additional disclosures, including a summary of our significant accounting policies. There have been no material changes to our significant accounting policies during the six months ended June 30, 2020, other than the adoption of the accounting pronouncements discussed herein. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal and recurring items, necessary for the fair presentation of our financial position, results of operations and cash flows for the interim periods presented.
Use of estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Future events and their effects cannot be predicted with certainty; accordingly, accounting estimates require the exercise of judgment. These financial statements were prepared using information reasonably available as of June 30, 2020 and through the date of this Report. The accounting estimates used in the preparation of the Company’s consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Actual results may differ from these estimates due to the uncertainty around the magnitude, duration and effects of the COVID-19 pandemic, as well as other factors.
Recent accounting pronouncements; Recently issued accounting pronouncements not yet adopted	Recent Accounting Pronouncements Recently adopted accounting pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13") that requires financial assets measured at amortized cost be presented at the net amount expected to be collected. Credit losses on available-for-sale debt securities should be recorded through an allowance for credit losses limited by the amount that the fair value is less than amortized cost. The amendments under ASU 2016-13 eliminate the probable incurred loss recognition model under GAAP and introduce a forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments. The estimate of expected credit losses requires entities to incorporate considerations of historical information, current information, and reasonable and supportable forecasts. The new ASU also expands the disclosure requirements to enable users of financial statements to understand the entity’s Note 2—Summary of Significant Accounting Policies (continued) assumptions, models, and methods for estimating expected credit losses. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost. Results for periods after January 1, 2020 are presented under ASU 2016-13 while prior period amounts continue to be reported under previously applicable accounting standards. The adoption of ASU 2016-13 resulted in an adjustment of approximately $0.3 million, net of tax, to beginning retained earnings, the effect of which we do not consider material to our consolidated financial statements. Most of our financial assets within the scope of ASU 2016-13 are considered highly short-term in nature and therefore, we are less susceptible to risks and uncertainty of credit losses over extended periods of time. The adoption of ASU 2016-13 did not result in any material changes to our methods for developing our allowance for credit losses, or the information we assess in developing our current estimate of expected credit losses. See Notes 4, 5 and 6 to these consolidated financial statements for additional information on our financial assets within scope of the new accounting standard. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other ("ASU 2017-04"): Simplifying the Test for Goodwill Impairment, which simplifies the existing two-step guidance for goodwill impairment testing by eliminating the second step resulting in a write-down to goodwill equal to the initial amount of impairment determined in step one. The ASU is to be applied prospectively for reporting periods beginning after December 15, 2019. We adopted the provisions of ASU 2017-04 on January 1, 2020, the effect of which did not have a material impact on our consolidated financial statements. Recently issued accounting pronouncements not yet adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain exceptions and improves consistent application of Topic 740. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of ASU 2019-12 on our consolidated financial statements.
Revenue from Contract with Customer	Within our Account Services segment, revenues recognized at a point in time are comprised principally of ATM fees, interchange, and other similar transaction-based fees. Revenues recognized over time consist of new card fees, monthly maintenance fees, revenue earned from gift cards and substantially all BaaS partner program management fees. Substantially all of our processing and settlement services are recognized at a point in time.
Fair value of financial instruments	Short-term Financial Instruments Our short-term financial instruments consist principally of unrestricted and restricted cash and cash equivalents, settlement assets and obligations, and obligations to customers. These financial instruments are short-term in nature, and, accordingly, we believe their carrying amounts approximate their fair values. Under the fair value hierarchy, these instruments are classified as Level 1. Investment Securities The fair values of investment securities have been derived using methodologies referenced in Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2019. Under the fair value hierarchy, our investment securities are classified as Level 2. Loans We determined the fair values of loans by discounting both principal and interest cash flows expected to be collected using a discount rate commensurate with the risk that we believe a market participant would consider in determining fair value. Under the fair value hierarchy, our loans are classified as Level 3. Deposits The fair value of demand and interest checking deposits and savings deposits is the amount payable on demand at the reporting date. We determined the fair value of time deposits by discounting expected future cash flows using market-derived rates based on our market yields on certificates of deposit, by maturity, at the measurement date. Under the fair value hierarchy, our deposits are classified as Level 2. Contingent Consideration The fair value of contingent consideration obligations, such as the earn-out associated with our acquisition of UniRush LLC ("UniRush") in 2017, is estimated through valuation models designed to estimate the probability of such contingent payments based on various assumptions. Estimated payments are discounted using present value techniques to arrive at an estimated fair value. Our contingent consideration payable is classified as Level 3 because we use unobservable inputs to estimate fair value, including the probability of achieving certain earnings thresholds and appropriate discount rates. Changes in fair value of contingent consideration are recorded through operating expenses. Debt The fair value of our revolving line of credit is based on borrowing rates currently available to a market participant for loans with similar terms or maturity. The carrying amount of our outstanding revolving line of credit approximates fair value because the base interest rate charged varies with market conditions and the credit spread is commensurate with current market spreads for issuers of similar risk. The fair value of the revolving line of credit is classified as a Level 2 liability in the fair value hierarchy. Fair Value of Financial Instruments The carrying values and fair values of certain financial instruments that were not carried at fair value, excluding short-term financial instruments for which the carrying value approximates fair value
