Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited financial information included in this report includes the accounts of FIS and its subsidiaries prepared in accordance with U.S. generally accepted accounting principles and the instructions to Form 10-Q and Article 10 of Regulation S-X. All adjustments considered necessary for a fair presentation have been included. This report should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported periods. The inputs into management's critical and significant accounting estimates consider the economic impact of the outbreak of the novel coronavirus ("COVID-19") and the subsequently declared COVID-19 pandemic ("the pandemic") by the World Health Organization on March 11, 2020. The extent to which the pandemic further affects our results of operations and financial position will depend on future developments, which are highly uncertain and are difficult to predict, including, but not limited to, the duration and spread of the pandemic and any recurrence or new strain of COVID-19, its severity, the success of vaccines or other actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. Accordingly, our future results could be materially affected by changes in our estimates. Certain reclassifications have been made in the 2020 consolidated financial statements to conform to the classifications used in 2021. Amounts in tables in the financial statements and accompanying footnotes may not sum due to rounding.

Transaction Price Allocated to the Remaining Performance Obligations As of June 30, 2021, approximately $22.5 billion of revenue is estimated to be recognized in the future primarily from the Banking Solutions and Capital Market Solutions segments' remaining unfulfilled performance obligations, which are primarily comprised of recurring account- and volume-based processing services. This excludes the amount of anticipated recurring renewals not yet contractually obligated. The Company expects to recognize approximately 30% of the Banking Solutions and Capital Market Solutions segments' remaining performance obligations over the next 12 months, approximately another 22% over the next 13 to 24 months, and the balance thereafter. As permitted by ASC 606, Revenue from Contracts with Customers , the Company has elected to exclude from this disclosure an estimate for the Merchant Solutions segment, which is primarily comprised of contracts with an original duration of one year or less or variable consideration that meet specific criteria. This segment's core performance obligations consist of variable consideration under a stand-ready series of distinct days of service, and revenue from the segment's products and service arrangements are generally billed and recognized as the services are performed. The aggregate fixed consideration portion of customer contracts with an initial contract duration greater than one year is not material.

Condensed Consolidated Financial Statement Details [Abstract]
Condensed Consolidated Financial Statement Details	Condensed Consolidated Financial Statement Details Cash and Cash Equivalents The Company includes restricted cash in the Cash and cash equivalents balance reported in the consolidated statements of cash flows. The reconciliation between Cash and cash equivalents in the consolidated balance sheets and the beginning and ending balances shown in the consolidated statement of cash flows is as follows (in millions): June 30, December 31, Cash and cash equivalents on the consolidated balance sheets $ 1,301 $ 1,959 Merchant float restricted cash (in Settlement deposits and merchant float) 1,984 2,071 Total Cash and cash equivalents per the consolidated statement of cash flows $ 3,285 $ 4,030 Allowance for Credit Losses The Company monitors trade receivables and contract assets as well as other receivable balances and estimates the allowance for lifetime expected credit losses. Estimates of expected credit losses are based on historical collection experience and other factors, including those related to current market conditions and events. The allowance for credit losses is separate from the chargeback liability described in Note 7. While the COVID-19 pandemic did not result in a significant increase in the Company's expected credit loss allowance recorded as of June 30, 2021, it is reasonably possible that future developments related to the economic impact of the COVID-19 pandemic could have a material impact on management's estimates. Property and Equipment, Intangible Assets and Computer Software The following table shows the Company's consolidated financial statement details as of June 30, 2021, and December 31, 2020 (in millions): June 30, 2021 December 31, 2020 Cost Accumulated Net Cost Accumulated Net Property and equipment $ 2,384 $ 1,520 $ 864 $ 2,292 $ 1,405 $ 887 Intangible assets $ 19,110 $ 6,352 $ 12,758 $ 19,141 $ 5,213 $ 13,928 Software $ 5,995 $ 2,597 $ 3,398 $ 5,535 $ 2,165 $ 3,370 As of June 30, 2021, intangible assets, net of amortization, includes $12,414 million of customer relationships and $344 million of trademarks and other intangible assets. Amortization expense with respect to these intangible assets was $598 million and $594 million for the three months and $1,193 million and $1,192 million for the six months ended June 30, 2021 and 2020, respectively. Goodwill Changes in goodwill during the six months ended June 30, 2021, are summarized below (in millions). Capital Corporate Merchant Banking Market And Solutions Solutions Solutions Other Total Balance, December 31, 2020 $ 36,267 $ 12,279 $ 4,702 $ 20 $ 53,268 Foreign currency adjustments (58) (12) (7) — (77) Balance, June 30, 2021 $ 36,209 $ 12,267 $ 4,695 $ 20 $ 53,191 We assess goodwill for impairment on an annual basis during the fourth quarter or more frequently if circumstances indicate potential impairment. For 2020, we completed our annual assessment for the Banking Solutions and Capital Market Solutions reporting units with qualitative assessments and concluded that it remained more likely than not that the fair value of each reporting unit continued to exceed its carrying value. For Merchant Solutions, we completed our 2020 annual assessment with a quantitative assessment due to the economic impact of the COVID-19 pandemic on our Merchant Solutions business and its primary operations having been recently acquired as part of the Worldpay acquisition completed on July 31, 2019. As a result of the annual assessment, the fair value of the reporting unit was estimated to be in excess of carrying amount by approximately 4%. Due to the continued economic impact of the COVID-19 pandemic, we evaluated if events and circumstances as of June 30, 2021, indicated potential impairment of our reporting units. We performed a qualitative assessment by examining factors most likely to affect our reporting units' fair values and considered the impact to our business from the COVID-19 pandemic. The factors examined involve significant use of management judgment and included, among others, (1) forecast revenue, growth rates, operating margins, and capital expenditures used to calculate estimated future cash flows, (2) future economic and market conditions and (3) FIS' market capitalization. Based on our interim impairment assessment as of June 30, 2021, we concluded that it remained more likely than not that the fair value continues to exceed the carrying amount for each of our reporting units; therefore, goodwill was not impaired. However, it is reasonably possible that future developments related to the economic impact of the COVID-19 pandemic on our Merchant Solutions business, such as an extended duration of the pandemic and/or government-imposed shutdowns, prolonged economic downturn or recession, or lack of governmental support for recovery, could have a material impact on one or more of the estimates and assumptions used to evaluate goodwill impairment and could result in future goodwill impairment. Visa Europe and Contingent Value Rights As part of the Worldpay acquisition, the Company acquired certain assets and liabilities related to the June 2016 Worldpay Group plc (Legacy Worldpay) disposal of its ownership interest in Visa Europe to Visa Inc. As part of the disposal, Legacy Worldpay received proceeds from Visa Inc. in the form of cash and convertible preferred stock ("preferred stock"), the value of which may be reduced by losses incurred relating to ongoing interchange-related litigation involving Visa Europe. Also in connection with the disposal, and pursuant to the terms of an amendment executed on September 17, 2020, the Company will pay the former Legacy Worldpay owners 90% of the net-of-tax proceeds from the disposal, known as contingent value rights, which is recorded as a liability ("CVR liability") on the consolidated balance sheets. The Company has elected the fair value option under ASC 825, Financial Instruments , for measuring its preferred stock asset and CVR liability. The fair value of the preferred stock was $100 million and $70 million at June 30, 2021, and December 31, 2020, respectively, recorded in Other noncurrent assets on the consolidated balance sheets. The fair value of the CVR liability was $418 million and $401 million at June 30, 2021, and December 31, 2020, respectively, recorded in Other noncurrent liabilities on the consolidated balance sheets. The net change in fair value was $9 million and $46 million for the three months and $14 million and $26 million for the six months ended June 30, 2021 and 2020, respectively, recorded in Other income (expense), net on the consolidated statements of earnings (loss).

These swaps are designated as fair value hedges for accounting purposes with a net liability fair value of $33 million reflected as a decrease in the long-term debt balance at June 30, 2021, and a net asset fair value of $10 million reflected as an increase in the long-term debt balance at December 31, 2020 (see Note 5). Net Investment Hedges The purpose of the Company's net investment hedges, as discussed below, is to reduce the volatility of FIS' net investment value in its Euro- and Pound Sterling-denominated operations due to changes in foreign currency exchange rates. The Company recorded net investment hedge aggregate gain (loss) for the change in fair value as Foreign currency translation adjustments and related income tax (expense) benefit within Other comprehensive earnings (loss), net of tax, on the consolidated statements of comprehensive earnings (loss) of $(29) million and $(201) million during the three months and $292 million and $334 million during the six months ended June 30, 2021 and 2020, respectively. No ineffectiveness has been recorded on the net investment hedges.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Reliance Trust Claims Reliance Trust Company ("Reliance"), the Company's subsidiary, is a defendant in a class action arising out of its provision of services as the discretionary trustee for a 401(k) Plan (the "Plan") for one of its customers. On behalf of the Plan participants, plaintiffs in the action, which was filed in December 2015, sought damages and attorneys' fees, as well as equitable relief, against Reliance and the Plan's sponsor and record-keeper for alleged breaches of fiduciary duty under the Employee Retirement Income Security Act of 1974 ("ERISA"). At a non-jury trial conducted in March 2020, Reliance vigorously defended the action and contended that no breaches of fiduciary duty or prohibited transactions occurred and that Plan participants suffered no damages. At trial, Plaintiffs claimed damages of approximately $127 million against all defendants. On October 12, 2020, Reliance and plaintiffs entered into a settlement agreement, which was subject to final court approval, to settle all allegations and claims asserted in the action for $39.8 million without equitable relief. On October 14, 2020, the Court preliminarily approved the settlement agreement. In the settlement agreement, Reliance admitted no wrongdoing or liability with respect to any of the allegations or claims and maintains that the Plan was managed, operated, and administered during its tenure as the Plan's discretionary trustee in full compliance with ERISA and applicable regulations. The Company recorded a liability for the agreed settlement amount of $39.8 million and a corresponding loss in Other income (expense), net on the consolidated statement of earnings (loss) during the quarter ended September 30, 2020. On March 8, 2021, the Court entered an order approving the settlement and entered a final judgment dismissing the action with prejudice. Reliance paid the full settlement amount in April 2021 and has met its monetary obligations under the settlement agreement. Brazilian Tax Authorities Claims In 2004, Proservvi Empreendimentos e Servicos, Ltda., the predecessor to Fidelity National Servicos de Tratamento de Documentos e Informatica Ltda. ("Servicos"), a subsidiary of Fidelity National Participacoes Ltda., our former item processing and remittance services operation in Brazil, acquired certain assets and employees and leased certain facilities from the Transpev Group ("Transpev") in Brazil. Transpev's remaining assets were later acquired by Prosegur, an unrelated third party. When Transpev discontinued its operations after the asset sale to Prosegur, it had unpaid federal taxes and social contributions owing to the Brazilian tax authorities. The Brazilian tax authorities brought a claim against Transpev and, beginning in 2012, brought claims against Prosegur and Servicos on the grounds that Prosegur and Servicos were successors in interest to Transpev. To date, the Brazilian tax authorities filed 14 claims against Servicos asserting potential tax liabilities of approximately $12 million. There are potentially 24 additional claims against Transpev/Prosegur for which Servicos is named as a co-defendant or may be named but for which Servicos has not yet been served. These additional claims amount to approximately $33 million, making the total potential exposure for all 38 claims approximately $45 million. We do not believe a liability for these 38 total claims is probable and, therefore, have not recorded a liability for any of these claims. Tax Receivable Agreement The Company assumed in the Worldpay acquisition a Tax Receivable Agreement ("TRA") under which the Company agreed to make payments to Fifth Third Bank ("Fifth Third") of 85% of the federal, state, local and foreign income tax benefits realized by the Company as a result of certain tax deductions. In December 2019, the Company entered into a Tax Receivable Purchase Addendum (the "Amendment") that provides written call and put options (collectively "the options") to terminate certain estimated obligations under the TRA in exchange for fixed cash payments. The remaining TRA obligations not subject to the Amendment are based on the cash savings realized by the Company by comparing the actual income tax liability of the Company to the amount of such taxes the Company would have been required to pay had there been no deductions related to the tax attributes. Under the TRA, in certain specified circumstances, such as certain changes of control, the Company may be required to make payments in excess of such cash savings. Obligations recorded in our consolidated financial statements pursuant to the TRA are based on estimates of future deductions and future tax rates and, in the case of the obligations subject to the Amendment, reflect management's expectation that the options will be exercised. The timing and/or amount of aggregate payments due under the TRA may vary based on a number of factors, including the exercise of options, the amount and timing of taxable income the Company generates in the future and the tax rate then applicable, the use of loss carryforwards and amortizable basis. Each reporting period, the Company evaluates the assumptions underlying the TRA obligations. The consolidated balance sheets as of June 30, 2021, and December 31, 2020, include a total liability of $448 million and $532 million, respectively, relating to the TRA. Chargeback Liability Through services offered in our Merchant Solutions segment, the Company is exposed to potential losses from merchant-related chargebacks. A chargeback occurs when a dispute between a cardholder and a merchant, including a claim for non-delivery of the product or service by the merchant, is not resolved in favor of the merchant and the transaction is charged back to the merchant resulting in a refund of the purchase price to the cardholder. If the Company is unable to collect this chargeback amount from the merchant due to closure, bankruptcy or other reasons, the Company bears the loss for the refund paid to the cardholder. The risk of chargebacks is typically greater for those merchants that promise future delivery of goods and services rather than delivering goods or rendering services at the time of payment. The economic impact of the COVID-19 pandemic has not resulted in material chargeback losses as of June 30, 2021; however, it is reasonably possible that the Company has incurred or may incur significant losses related to future chargebacks. Due to the unprecedented nature of the pandemic and the numerous current and future uncertainties that may impact any potential chargeback losses, and considering that the Company has no historical experience with similar uncertainties, a reasonable estimate of the possible accrual for future chargeback losses or range of losses cannot be made. Indemnifications and Warranties The Company generally indemnifies its clients, subject to certain limitations and exceptions, against damages and costs resulting from claims of patent, copyright, or trademark infringement associated solely with its customers' use of the Company's software applications or services. Historically, the Company has not made any material payments under such indemnifications but continues to monitor the conditions that are subject to the indemnifications to identify whether it is probable that a loss has occurred, in which case it would recognize any such losses when they are estimable. In addition, the Company warrants to customers that its software operates substantially in accordance with the software specifications. Historically, no material costs have been incurred related to software warranties, and no accruals for warranty costs have been made.

The modification implemented a new retirement policy that permits retirees that meet certain eligibility criteria to continue vesting in unvested equity awards in accordance with the terms of the respective grant agreements, resulting in accelerated stock compensation expense for those employees meeting the definition of retirement eligible. During the quarter ended March 31, 2021, the Company recorded $104 million in accelerated stock compensation expense included in Selling, general, and administrative expenses in the consolidated statement of earnings (loss) to reflect the impact of the modification on unvested equity awards outstanding at January 1, 2021.

Related-Party Transactions	Related-Party Transactions The Company held a noncontrolling ownership stake in Cardinal Holdings ("Cardinal"), which operated the Capco consulting business, through April 29, 2021, when we sold our ownership stake due to an acquisition transaction of the Capco consulting business by Wipro Ltd. As a result of the transaction, we received net cash proceeds of approximately $367 million and recorded an approximately $225 million gain in Other income (expense), net on the consolidated statement of earnings (loss). FIS' ownership stake in Cardinal was 36% at the date of sale and December 31, 2020. Prior to the sale, the Company recorded the ownership stake in Cardinal as an equity method investment included within Other noncurrent assets on the consolidated balance sheet. The carrying value of this equity method investment was $137 million at December 31, 2020. FIS provides ongoing management consulting services and other services to Cardinal. FIS also purchases services and software licenses from Cardinal from time to time. Cardinal was a related party through April 29, 2021. Amounts transacted through these agreements were not significant to the 2021 and 2020 periods presented when Cardinal was a related party.

Segment Reporting [Abstract]
Segment Information	Segment Information FIS reports its financial performance based on the following segments: Merchant Solutions, Banking Solutions, Capital Market Solutions and Corporate and Other. The Company regularly assesses its portfolio of assets and reclassified certain non-strategic businesses from the Merchant Solutions, Banking Solutions, and Capital Market Solutions segments into the Corporate and Other segment during the year ended December 31, 2020, and recast all prior-period segment information presented. Below is a summary of each segment. Merchant Solutions ("Merchant") The Merchant segment is focused on serving merchants of all sizes globally, enabling them to accept electronic payments, including card-based payments, contactless card and mobile wallet, originated at a physical point of sale, as well as card-not-present payments in eCommerce and mobile environments. Merchant services include all aspects of payment processing, including authorization and settlement, customer service, chargeback and retrieval processing, electronic payment transaction reporting and network fee and interchange management. Merchant also includes value-added services, such as security and fraud prevention solutions, advanced data analytics and information management solutions, foreign currency management and numerous funding options. Merchant serves clients in over 140 countries. Our Merchant clients are highly-diversified, including global enterprises, national retailers and small- to medium-sized businesses. The Merchant segment utilizes broad and varied distribution channels, including direct sales forces and multiple referral partner relationships that provide us with a growing and diverse client base. Banking Solutions ("Banking") The Banking segment is focused on serving all sizes of financial institutions with core processing software, transaction processing software and complementary applications and services, many of which interact directly with the core processing applications. We sell these solutions and services on either a bundled or stand-alone basis. Clients in this segment include global financial institutions, U.S. regional and community banks, credit unions and commercial lenders, as well as government institutions and other commercial organizations. Banking serves clients in more than 100 countries. We provide our clients integrated solutions characterized by multi-year processing contracts that generate highly recurring revenue. The predictable nature of cash flows generated from the Banking segment provides opportunities for further investments in innovation, integration, information and security, and compliance in a cost-effective manner. Capital Market Solutions ("Capital Markets") The Capital Markets segment is focused on serving global financial services clients with a broad array of buy- and sell-side solutions. Clients in this segment operate in more than 100 countries and include asset managers, buy- and sell-side securities brokerage and trading firms, insurers, private equity firms, and other commercial organizations. Our buy- and sell-side solutions include a variety of mission-critical applications for recordkeeping, data and analytics, trading, financing and risk management. Capital Markets clients purchase our solutions and services in various ways including licensing and managing technology "in-house," using consulting and third-party service providers, as well as procuring fully outsourced end-to-end solutions. Our long-established relationships with many of these financial and commercial institutions generate significant recurring revenue. We have made, and continue to make, investments in modern platforms; advanced technologies, such as cloud delivery, open APIs, machine learning and artificial intelligence; and regulatory technology to support our Capital Markets clients. Corporate and Other The Corporate and Other segment consists of corporate overhead expense, certain leveraged functions and miscellaneous expenses that are not included in the operating segments, as well as certain non-strategic businesses that we plan to wind down or sell. The overhead and leveraged costs relate to corporate marketing, corporate finance and accounting, human resources, legal, and amortization of acquisition-related intangibles and other costs, such as acquisition and integration expenses, that are not considered when management evaluates revenue-generating segment performance. The Company recorded acquisition and integration costs primarily related to the Worldpay acquisition, as well as certain other costs associated with data center consolidation activities totaling $12 million and $22 million for the three months ended and $28 million and $40 million for the six months ended June 30, 2021 and 2020, respectively. The Company also recorded incremental costs directly related to COVID-19 of $10 million and $12 million for the three months ended and $19 million and $15 million for the six months ended June 30, 2021 and 2020, respectively. For the six months ended June 30, 2021, we also recorded $104 million in accelerated stock compensation expense to reflect the impact of establishing a Qualified Retirement Equity Program that modified unvested equity awards outstanding at January 1, 2021 (see Note 8). Adjusted EBITDA Adjusted EBITDA is a measure of segment profit or loss that is reported to the chief operating decision maker for purposes of making decisions about allocating resources to the segments and assessing their performance. For this reason, Adjusted EBITDA, as it relates to our segments, is presented in conformity with FASB ASC Topic 280, Segment Reporting . Adjusted EBITDA is defined as net earnings (loss) before net interest expense, net other income (expense), income tax provision (benefit), equity method investment earnings (loss), and depreciation and amortization, and excludes certain costs and other transactions that management deems non-operational in nature. The non-operational items affecting the segment profit measure generally include the amortization of purchase accounting adjustments as well as acquisition, integration and certain other costs. Adjusted EBITDA also excludes incremental and direct costs resulting from the COVID-19 pandemic. These costs and adjustments are recorded in the Corporate and Other segment for the periods discussed below. Adjusted EBITDA for the respective segments excludes the foregoing costs and adjustments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The unaudited financial information included in this report includes the accounts of FIS and its subsidiaries prepared in accordance with U.S. generally accepted accounting principles and the instructions to Form 10-Q and Article 10 of Regulation S-X. All adjustments considered necessary for a fair presentation have been included. This report should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported periods. The inputs into management's critical and significant accounting estimates consider the economic impact of the outbreak of the novel coronavirus ("COVID-19") and the subsequently declared COVID-19 pandemic ("the pandemic") by the World Health Organization on March 11, 2020. The extent to which the pandemic further affects our results of operations and financial position will depend on future developments, which are highly uncertain and are difficult to predict, including, but not limited to, the duration and spread of the pandemic and any recurrence or new strain of COVID-19, its severity, the success of vaccines or other actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. Accordingly, our future results could be materially affected by changes in our estimates.
Segments	FIS reports its financial performance based on the following segments: Merchant Solutions, Banking Solutions, Capital Market Solutions, and Corporate and Other. The Company regularly assesses its portfolio of assets and reclassified certain non-strategic businesses from the Merchant Solutions, Banking Solutions, and Capital Market Solutions segments into the Corporate and Other segment during the year ended December 31, 2020, and recast all prior-period segment information presented.
Allowance for Credit Losses	The Company monitors trade receivables and contract assets as well as other receivable balances and estimates the allowance for lifetime expected credit losses. Estimates of expected credit losses are based on historical collection experience and other factors, including those related to current market conditions and events. The allowance for credit losses is separate from the chargeback liability described in Note 7.
