Summary of Significant Accounting Policies (Policies)	Mar. 31, 2024
Accounting Policies [Abstract]
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, 2023 for additional disclosures, including a summary of our significant accounting policies. There have been no material changes to our significant accounting policies during the three months ended March 31, 2024. 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 March 31, 2024 and through the date of this report. The accounting estimates used in the preparation of our consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained, and as our operating environment changes. Actual results may differ from these estimates due to a variety of factors, including those identified under Part II, Item 1A. "Risk Factors" in this report.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the Financial Standards Accounting Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for our annual periods beginning January 1, 2024, and for interim periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the potential effect that the updated standard will have on our financial statement disclosures. In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for our annual periods beginning January 1, 2025, with early adoption permitted. We are currently evaluating the potential effect that the updated standard will have on our financial statement disclosures.
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, 2023. 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. 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.
