Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accompanying Condensed Consolidated Financial Statements have been prepared by NCR Corporation (NCR, the Company, we or us) without audit pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC) and, in the opinion of management, include all adjustments (consisting of normal, recurring adjustments, unless otherwise disclosed) necessary for a fair statement of the condensed consolidated results of operations, financial position, and cash flows for each period presented. The consolidated results for the interim periods are not necessarily indicative of results to be expected for the full year. The 2020 year-end Condensed Consolidated Balance Sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States (GAAP). These financial statements should be read in conjunction with NCR’s Form 10-K for the year ended December 31, 2020. On June 21, 2021, we completed the acquisition of Cardtronics plc (“Cardtronics”). The September 30, 2021 year to date results include the operations of Cardtronics from June 21, 2021 to September 30, 2021 and the results for the quarter ended September 30, 2021 include a full three months for Cardtronics. Refer to Note 2, Business Combinations for additional disclosure. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the period reported. Although our estimates contemplate current and expected future conditions, as applicable, it is reasonably possible that actual conditions could differ from our expectations, which could materially affect our results of operations and financial position. In particular, a number of estimates have been and will continue to be affected by the ongoing novel coronavirus (COVID-19) pandemic. The ultimate impact on our overall financial condition and operating results will depend on the currently unknowable duration and severity of the pandemic, supply chain challenges and cost escalations including materials, labor and freight, and any additional governmental and public actions taken in response. As a result, our accounting estimates and assumptions may change over time as a consequence of the effects of COVID-19. Such changes could result in future impairments of goodwill, intangible assets, long-lived assets, incremental credit losses on accounts receivable and decreases in the carrying amount of our tax assets. Evaluation of Subsequent Events The Company evaluated subsequent events through the date that our Condensed Consolidated Financial Statements were issued. No matters were identified that required adjustment of the Condensed Consolidated Financial Statements or additional disclosure other than subsequent events disclosed within the notes to the Condensed Consolidated Financial Statements. Reclassifications Certain prior-period amounts have been reclassified in the accompanying Condensed Consolidated Financial Statements and Notes thereto in order to conform to the current period presentation. Reclassifications had no effect on prior year net income or shareholders’ equity. Cash, Cash Equivalents, and Restricted Cash The reconciliation of cash, cash equivalents and restricted cash in the Condensed Consolidated Statements of Cash Flows is as follows: In millions September 30 2021 2020 Cash and cash equivalents $ 383 $ 1,605 Long term restricted cash included in other assets 6 9 Funds held for clients included in restricted cash 41 26 Cash included in settlement processing assets included in restricted cash 205 18 Total cash, cash equivalents and restricted cash $ 635 $ 1,658 Contract Assets and Liabilities The following table presents the net contract asset and contract liability balances as of September 30, 2021 and December 31, 2020. In millions Location in the Condensed Consolidated Balance Sheet September 30, 2021 December 31, 2020 Current portion of contract liabilities Contract liabilities $ 540 $ 507 Non-current portion of contract liabilities Other liabilities $ 62 $ 80 During the nine months ended September 30, 2021, the Company recognized $406 million in revenue that was included in contract liabilities as of December 31, 2020. Remaining Performance Obligations Remaining performance obligations represent the transaction price of orders for which products have not been delivered or services have not been performed. As of September 30, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $3.7 billion. The Company expects to recognize revenue on approximately three-quarters of the remaining performance obligations over the next 12 months, with the remainder recognized thereafter. The majority of our professional services are expected to be recognized over the next 12 months but this is contingent upon a number of factors, including customers’ needs and schedules. The Company has made two elections that affect the value of remaining performance obligations described above. We do not disclose remaining performance obligations for contracts where variable consideration is directly allocated based on usage or when the original expected length is one year or less. Recent Accounting Pronouncements Issued In August 2020, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update with new guidance for convertible preferred stock, which eliminates considerations related to the beneficial conversion feature model. The standard also requires an average stock price when calculating the denominator for diluted earnings per share to be used for stock units where the settlement of the number of shares is based on the stock price. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early adoption is permitted no earlier than fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. The adoption of this accounting standards update is not expected to have a material effect on the Company's net income, cash flows, earnings per share or financial condition. In May 2021, the FASB issued an accounting standards update with new guidance for freestanding equity-classified written call options. The new guidance requires modifications or exchanges of freestanding equity-classified written call options that remain equity classified after the modification or exchange based on the economic substance of the modification or exchange. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted.

Business Combinations [Abstract]
Mergers, Acquisitions and Dispositions Disclosures	2. BUSINESS COMBINATIONS Pending acquisition of LibertyX On July 31, 2021, NCR entered into a definitive agreement to acquire Moon Inc. dba LibertyX, a leading cryptocurrency software provider. The transaction is expected to close later in 2021, subject to customary closing conditions, including obtaining certain regulatory licensing consents and approvals. Acquisition of Cardtronics plc On January 25, 2021, NCR entered into a definitive agreement to acquire all outstanding shares of Cardtronics plc (“Cardtronics”) for $39.00 per share (the “Cardtronics Transaction”). The legal closing of the Cardtronics Transaction occurred on June 21, 2021. Cardtronics is the world's largest non-bank ATM operator and service provider enabling cash transactions by converting digital currency into physical cash at over 285,000 ATMs across 10 countries in North America, Europe, Asia-Pacific, and Africa. The Cardtronics Transaction is expected to accelerate our NCR-as-a-service strategy and enhance our ability to provide technology solutions and capabilities that run our customers’ businesses. Purchase Price Consideration The purchase consideration transferred consisted of the following: In millions Purchase Consideration Cash paid to common stockholders and holders of certain restricted stock and stock option awards $ 1,775 Debt repaid by NCR on behalf of Cardtronics 809 Transaction costs paid by NCR on behalf of Cardtronics 57 Fair value of converted Cardtronics awards attributable to pre-combination services 19 Settlement of pre-existing relationships 14 Total purchase consideration $ 2,674 Other than certain outstanding restricted stock and stock option awards issued to directors which were paid out in cash at closing, the Company converted outstanding unvested Cardtronics awards into NCR awards pursuant to an exchange ratio as defined in the acquisition agreement. Each restricted stock award that was outstanding, whether performance-based or time-based, was converted into time-based awards, and will continue to be governed by the same vesting terms as the original Cardtronics awards. Cardtronics stock option awards were converted into NCR stock option awards with an exercise price per share for option awards equal to the exercise price per share of such stock option award immediately prior to the completion of the acquisition divided by the exchange ratio, and will continue to be governed generally by the same terms and conditions as were applicable prior to the acquisition. The amounts attributable to services already rendered were included as an adjustment to the purchase price and the amounts attributable to future services will be expensed over the remaining vesting period, net of estimated forfeitures. The fair value of options that the Company assumed in connection with the acquisition of Cardtronics were estimated using the Black-Scholes model. Recording of Assets Acquired and Liabilities Assumed The fair value of consideration transferred to acquire Cardtronics was allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair values as of the date of the acquisition as set forth below. The preliminary allocation of the purchase price for Cardtronics is as follows: In millions Fair Value Assets acquired Cash and restricted cash acquired $ 296 Trade accounts receivable 84 Prepaid expenses, other current assets and other assets 154 Property, plant and equipment 359 Estimated acquisition-related intangible assets 877 Total assets acquired $ 1,770 Liabilities assumed 690 Net assets acquired, excluding goodwill 1,080 Total purchase consideration 2,674 Estimated goodwill $ 1,594 We recorded a preliminary allocation of the purchase price to tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of June 21, 2021. The provisional amounts for intangible assets are based on third-party valuations performed. Additionally, further adjustments to the purchase price allocation will be required, within the measurement period, once the Company is able to complete more detailed procedures, and additional refinement to finalize valuations, among other items. Goodwill represents the future economic benefits arising from other assets acquired that could not be separately recognized. The goodwill arising from the acquisition consists of revenue and cost synergies expected from combining the operations of NCR and Cardtronics. It is expected that approximately $153 million of the goodwill recognized in connection with the acquisition will be deductible for tax purposes. The goodwill arising from the acquisition has been allocated to our Banking segment. Refer to Note 3, Goodwill and Long-Lived Assets, for the carrying amounts of goodwill by segment as of September 30, 2021. The following table sets forth the components of the intangible assets acquired as of the acquisition date: Fair Value Weighted Average Amortization Period (1) (In millions) (In years) Direct customer relationships $ 340 15 Technology - Software 485 8 Non-compete 1 1 Tradenames 51 5 Total acquired intangible assets $ 877 (1) Determination of the weighted average period of the individual categories of intangible assets was based on the nature of applicable intangible asset and the expected future cash flows to be derived from the intangible asset. Amortization of intangible assets with definite lives is recognized over the period of time the assets are expected to contribute to future cash flows. In connection with the closing of the acquisition, the Company incurred transaction costs of zero and $46 million in the three and nine months ended September 30, 2021, respectively, which has been included within selling, general and administrative expenses in the Condensed Consolidated Statement of Operations.

These segments represent components of the Company for which separate financial information is available that is utilized on a regular basis by the chief operating decision maker in assessing segment performance and in allocating the Company's resources. Management evaluates the performance of the segments based on revenue and adjusted EBITDA. The Company previously evaluated the performance of the segments based on segment operating income. Adjusted EBITDA is defined as GAAP net income (loss) from continuing operations attributable to NCR plus interest expense, net; plus income tax expense (benefit); plus depreciation and amortization; plus stock-based compensation expense; plus other income (expense); plus pension mark-to-market adjustments, pension settlements, pension curtailments and pension special termination benefits and other special items, including amortization of acquisition-related intangibles, restructuring charges, among others. The special items are considered non-operational so are excluded from the adjusted EBITDA metric utilized by our chief operating decision maker in evaluating segment performance and are separately delineated to reconcile back to total reported GAAP net income (loss) from operations attributable to NCR. Assets are not allocated to segments, and thus are not included in the assessment of segment performance. Consequently, we do not disclose total assets by reportable segment. The accounting policies used to determine the results of the operating segments are the same as those utilized for the condensed consolidated financial statements as a whole. Intersegment sales and transfers are not material. Corporate and Other reconciles our segment results to adjusted EBITDA, which primarily includes other income (expense) that are managed only on a total company basis and are, accordingly, reflected only in consolidated results. The following table presents revenue and adjusted EBITDA by segment: In millions Three months ended September 30 Nine months ended September 30 2021 2020 2021 2020 Revenue by segment Banking $ 1,050 $ 777 $ 2,615 $ 2,303 Retail 553 556 1,661 1,511 Hospitality 223 173 617 502 T&T 75 83 229 260 Consolidated revenue $ 1,901 $ 1,589 $ 5,122 $ 4,576 Adjusted EBITDA by Segment Banking $ 242 $ 144 $ 547 $ 414 Retail 70 81 235 167 Hospitality 35 24 90 46 T&T 10 10 29 28 Corporate and Other (5) (10) (10) (17) Total Adjusted EBITDA $ 352 $ 249 $ 891 $ 638 For the three and nine months ended September 30, 2021, the operations of Cardtronics are included in the banking segment from the close date June 21, 2021.

Senior Secured Credit Facility As previously disclosed, on February 4, 2021 the Company entered into a fourth amendment to the Senior Secured Credit Facility, and, on February 16, 2021 the Company entered into (a) an amended and restated commitment letter (the “Commitment Letter” ), with certain financial institutions party thereto (collectively, the “Commitment Parties”) , (b) an incremental term loan A facility agreement (the Incremental Term Agreement) with the financial institutions party thereto as lenders, NCR International, Inc. (the “Guarantor Subsidiary” ), and JPMorgan Chase Bank N.A., as the administrative agent (in such capacity, the “Administrative Agent” ) and (c) an incremental revolving facility agreement (the “Incremental Revolving Agreement” ) with certain financial institutions party thereto as lenders, the Guarantor Subsidiary, certain of the subsidiaries of NCR as borrowers (collectively, the “Foreign Borrowers” ) and the Administrative Agent. Pursuant to the Commitment Letter, the Company obtained commitments for a senior bridge facility (which was intended to be secured, but a portion of which may have been unsecured) in an aggregate principal amount of $1.0 billion (the “Bridge Facility”). The Bridge Facility would have been available to the Company for the purpose of financing the Cardtronics Transaction, if, and to the extent, certain securities offerings were not issued on or prior to the closing of the Cardtronics Transaction. As noted below, on April 6, 2021, the Company issued $1.2 billion aggregate principal amount of 5.125% senior notes due 2029 (the “ 5.125% Notes”) which financed a portion of the purchase price consideration in connection with the Cardtronics Transaction. As a result, the commitments with respect to the Bridge Facility were terminated . Pursuant to the Incremental Term Agreement, the Company obtained a senior secured incremental term loan A facility under the Senior Secured Credit Facility, in an aggregate principal amount of $1.505 billion (the “TLA Facility” ). The senior secured credit facility also includes a senior secured term loan B facility (the “TLB Facility” ) in an aggregate principal amount of $750 million. Pursuant to the Incremental Revolving Agreement, the lenders party thereto provided the Company and the Foreign Borrowers with a $1.1 billion revolving credit facility under the Senior Secured Credit Facility to replace the Company’s existing senior secured revolving credit facility. The revolving credit facility also allows a sub-facility that may be used for letters of credit, and, as of September 30, 2021, outstanding letters of credit were $26 million. On June 24, 2021 (the “Conversion Effective Date”), the Company entered into an Incremental Revolving Facility Agreement (TLA-2 Conversion) (the “Incremental Revolving Conversion Agreement”), with the Guarantor Subsidiary and the Foreign Borrowers, the lenders party thereto and the Administrative Agent. Pursuant to the Incremental Revolving Conversion Agreement, $200 million of the TLA Facility was converted into an equal principal amount of senior secured incremental revolving credit commitments (the “Incremental Revolving Commitments”). The Incremental Revolving Conversion Agreement also amends and restates the credit agreement (the “Amended and Restated Credit Agreement”) to reflect, among other things, the Incremental Revolving Commitments, the TLA Facility and the Replacement Revolving Facility. As a result, the aggregate principal amount under the TLA Facility is $1.305 billion and under the revolving credit facility is $1.3 billion. As of September 30, 2021, the term loan facilities (the TLA Facility and the TLB Facility) under the Senior Secured Credit Facility have an aggregate principal amount of $2.055 billion, of which $1.940 billion was outstanding. Additionally, as of September 30, 2021, there was $385 million outstanding under the revolving credit facility. The terms of the Incremental Revolving Commitments are identical to the terms of the commitments under the Replacement Revolving Facility (together with the Incremental Revolving Commitments, the “Revolving Credit Facility”). Up to $400 million of the revolving credit facility is available to the Foreign Borrowers, as long as there is availability under the revolving credit facility. Term loans were made to the Company in U.S. Dollars, and loans under the revolving credit facility are available in U.S. Dollars, Euros and Pound Sterling. The outstanding principal balance of the TLB facility is required to be repaid in equal quarterly installments of 0.25% of the original aggregate principal amount that began with the fiscal quarter ending December 31, 2019, with the balance being due at maturity on August 28, 2026 (the “TLB Maturity Date”). The outstanding principal balance of the TLA Facility is required to be repaid in equal quarterly installments of 1.875% of the original aggregate principal amount thereof, beginning with the fiscal quarter ending September 30, 2021, with the balance being due at maturity on the earlier of (a) June 21, 2026 and (b) unless the loans under TLB Facility have been repaid prior to such date, the date that is 91 days prior to the TLB Maturity Date. Commitments under the Revolving Credit Facility are scheduled to terminate on the earlier of (a) June 21, 2026 and (b) unless the loans under TLB Facility have been repaid prior to such date, the date that is 91 days prior to the TLB Maturity Date. Loans under the Revolving Credit Facility may be repaid and reborrowed prior to such date, subject to the satisfaction of customary conditions. Amounts covered under the Revolving Credit Facility and the TLA Facility bear interest at LIBOR (or, in the case of amounts denominated in Euros, EURIBOR), or, at our option, in the case of amounts denominated in Dollars, at a base rate equal to the highest of (i) the federal funds rate plus 0.50%, (ii) the rate of interest last quoted by the Wall Street Journal as the “prime rate”, (iii) the one-month LIBOR rate plus 1.00%, and (iv) 0.00% per annum (the “Base Rate”), plus, in each case, a margin ranging from 1.25% to 2.75% per annum for LIBOR-based and EURIBOR-based loans under such facilities and ranging from 0.25% to 1.75% per annum for Base Rate-based loans under such facilities, in each case, depending on our consolidated leverage ratio. Until we deliver financial statements for the fiscal quarter ended September 30, 2021, the applicable margin will be 2.50% for LIBOR-based and EURIBOR-based loans under such facilities and 1.50% for loans under such facilities. Amounts borrowed under the TLB Facility bear interest at LIBOR or, at our option, at the Base Rate, plus, in each case, a margin of 2.50% per annum for LIBOR-based loans and 1.50% per annum for Base Rate-based loans. The Amended and Restated Credit Agreement contains customary LIBOR and EURIBOR replacement provisions. The daily unused portion of the Revolving Credit Facility is subject to a commitment fee ranging from 0.15% to 0.45% per annum, depending on our consolidated leverage ratio. The obligations under the Senior Secured Credit Facility are guaranteed by certain of the Company’s domestic material subsidiaries including the Guarantor Subsidiary and certain domestic subsidiaries acquired through the Cardtronics Transaction that joined as guarantors on September 30, 2021 (collectively, the “Cardtronics Guarantors” and together with the Guarantor Subsidiary, the “Guarantors”). The obligations under the Senior Secured Credit Facility and the above described guarantee are secured by a first priority lien and security interest in certain equity interests owned by the Company and the Guarantors in certain of their respective domestic and foreign subsidiaries, and a first priority lien and security interest in substantially all of the assets of the Company and the Guarantors, subject to certain exclusions. These security interests would be released if the Company achieves an “investment grade” rating and will remain released so long as the Company maintains that rating. The Senior Secured Credit Facility includes affirmative and negative covenants that restrict or limit the ability of the Company and its subsidiaries to, among other things, incur indebtedness; create liens on assets; engage in certain fundamental corporate changes or changes to the Company's business activities; make investments; sell or otherwise dispose of assets; engage in sale-leaseback or hedging transactions; repurchase stock, pay dividends or make similar distributions; repay other indebtedness; engage in certain affiliate transactions; or enter into agreements that restrict the Company's ability to create liens, pay dividends or make loan repayments. The Senior Secured Credit Facility also includes a financial covenant with respect to the Revolving Credit Facility and the TLA Facility. The financial covenant requires the Company to maintain: • A consolidated leverage ratio on the last day of any fiscal quarter, not to exceed (i) in the case of any fiscal quarter ending on or prior to December 31, 2021, 5.50 to 1.00, (ii) in the case of any fiscal quarter ending on or prior to September 30, 2022, 5.25 to 1.00, and (iii) in the case of any fiscal quarter ending on or after December 31, 2022, 4.75 to 1.00. The Company has the option to elect to increase the maximum permitted leverage ratio for the periods described in the foregoing clause (iii) by 0.25 in connection with the consummation of any material acquisition (as defined in the Senior Secured Credit Facility) for three fiscal quarters. The Senior Secured Credit Facility also includes provisions for events of default, which are customary for similar financings. Upon the occurrence of an event of default, the lenders may, among other things, terminate the loan commitments, accelerate all loans and require cash collateral deposits in respect of outstanding letters of credit. If the Company is unable to pay or repay the amounts due, the lenders could, among other things, proceed against the collateral granted to them to secure such indebtedness. For the three and nine months ended September 30, 2021, the Company incurred financing fees of zero and $19 million, respectively, related to certain structuring and commitment fees as a result of the above referenced financing transactions entered into during the first quarter of 2021. The Company may request, at any time and from time to time one or more incremental term loans and/or revolving credit facilities (subject to the agreement of existing lenders or additional financial institutions to provide such term loans and/or revolving credit facilities) and with no requirement that existing lenders providing such facilities with commitments in an aggregate amount not to exceed the greater of (i) $150 million, and (ii) such amount as would not cause the leverage ratio under the Senior Secured Credit Facility, calculated on a pro forma basis including the incremental facility and assuming that it and the revolver are fully drawn, to exceed 3.00 to 1.00, and the proceeds of which can be used for working capital requirements and other general corporate purposes. Senior Unsecured Notes On August 21, 2019, the Company issued $500 million aggregate principal amount of 5.750% senior unsecured notes due in 2027 (the “5.750% Notes”) and $500 million aggregate principal amount of 6.125% senior unsecured notes due in 2029 (the “6.125% Notes”). The 5.750% Notes were sold at 100% of the principal amount with a maturity date of September 1, 2027. The 6.125% Notes were sold at 100% of the principal amount with a maturity date of September 1, 2029. On August 20, 2020, the Company issued $650 million aggregate principal amount of 5.000% senior unsecured notes due in 2028 (the “5.000% Notes”) and $450 million aggregate principal amount of 5.250% senior unsecured notes due in 2030 (the 5.250% Notes). The 5.000% Notes and 5.250% Notes were sold at 100% of the principal amount and with maturity dates of October 1, 2028 and October 1, 2030, respectively. The senior unsecured notes are guaranteed by certain of the Company's domestic material subsidiaries (including the Guarantor Subsidiary and the Cardtronics Guarantors that joined as guarantors on October 14, 2021), which have guaranteed fully and unconditionally the obligations to pay principal and interest for these senior unsecured notes. The terms of the indentures for these notes limit the ability of the Company and certain of its subsidiaries to, among other things, incur additional debt or issue redeemable preferred stock; pay dividends or make certain other restricted payments or investments; incur liens; sell assets; incur restrictions on the ability of the Company's subsidiaries to pay dividends to the Company; enter into affiliate transactions; engage in sa le and leaseback transactions; and consolidate, merge, sell or otherwise dispose of all or substantially all of the Company's or such subsidiaries' assets. These covenants are subject to significant exceptions and qualifications. For example, if these notes are assigned an “investment grade” rating by Moody's or S&P and no default has occurred or is continuing, certain covenants will be terminated. On April 6, 2021, the Company issued the 5.125% Notes due 2029. The Company used the net proceeds from the issuance of the 5.125% Notes, together with the borrowing under its senior secured credit facilities to finance the consideration paid in connection with the Cardtronics Transaction. The 5.125% Notes are senior unsecured obligations of the Company and guaranteed by the Guarantors. Interest is payable on the 5.125% Notes semi-annually in arrears at annual rates of 5.125% on April 15 and October 15 of each year, beginning on October 15, 2021. The 5.125% Notes will mature on April 15, 2029. At any time and from time to time, prior to April 15, 2024, the Company may redeem up to a maximum of 40% of the original aggregate principal amount of the 5.125% Notes with the proceeds of one or more equity offerings, at a redemption price equal to 105.125% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but not including, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that: (i) at least 55% of the original aggregate principal amount of the applicable 5.125% Notes remains outstanding; and (ii) such redemption occurs within 180 days of the completion of such equity offering. Prior to April 15, 2024, the Company may redeem some or all of the 5.125% Notes by paying a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus the applicable premium, as defined in the applicable indenture, as of, and accrued and unpaid interest to, but excluding, the applicable redemption date (subject to the right of holders of record of the applicable 5.125% Notes on the relevant record date to receive interest due on the relevant interest payment date). On or after April 15 of the relevant year listed below, the Company may redeem some or all of the 5.125% Notes at the prices listed below, plus accrued and unpaid interest, if any, to, but not including, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date): 2024 at a redemption price of 102.563%, 2025 at a redemption price of 101.281%, and 2026 and thereafter at a redemption price of 100%. The 5.125% Notes contains customary events of default, including, among other things, payment default, exchange default, failure to provide certain notices thereunder and certain provisions related to bankruptcy events. The indenture also contains customary high yield affirmative and negative covenants, including negative covenants that, among other things, limit the Company and its restricted subsidiaries’ ability to incur additional indebtedness, create liens on, sell or otherwise dispose of assets, engage in certain fundamental corporate changes or changes to lines of business activities, make certain investments or material acquisitions, engage in sale-leaseback or hedging transactions, repurchase common stock, pay dividends or make similar distributions on capital stock, repay certain indebtedness, engage in certain affiliate transactions and enter into agreements that restrict their ability to create liens, pay dividends or make loan repayments. On August 12, 2021 (the “Redemption Date”) the $400 million 8.125% Notes were redeemed, at a redemption premium of 109.136% of the aggregate principal amount. As part of the debt extinguishment, we recognized a loss of $42 million, which includes the write-off of deferred financing fees of $5 million and a cash redemption premium of $37 million. Trade Receivables Facility In November 2014, the Company established a revolving trade receivables facility (the “T/R Facility”) with PNC Bank, National Association ("PNC"). On September 30, 2021, the principal agreements for the T/R Facility were amended and restated to allow the Company's wholly-owned, bankruptcy remote subsidiary NCR Receivables LLC (the "U.S. SPE") to sell to PNC and the other financial institutions participating in the T/R Facility an undivided ownership interest in a portion of the trade receivables owned by the U.S. SPE. In connection with this amendment and restatement, the U.S. SPE repaid in full its outstanding indebtedness under the T/R Facility and agreed to terminate and replace the lending commitments of PNC and the other financial institutions thereunder with commitments to purchase the U.S. SPE's trade receivables. Refer to Note 6, Trade Receivables Facility in the notes to the condensed consolidated financial statements for more information. Fair Value of Debt The Company utilized Level 2 inputs, as defined in the fair value hierarchy, to measure the fair value of the long-term debt, which, as of September 30, 2021 and December 31, 2020 was $5.75 billion and $3.49 billion, respectively. Management's fair value estimates were based on quoted prices for recent trades of NCR’s long-term debt, quoted prices for similar instruments, and inquiries with certain investment communities.

Receivables [Abstract]
Loans, Notes, Trade and Other Receivables Disclosure	6. TRADE RECEIVABLES FACILITY On September 30, 2021 the Company and the U.S. bankruptcy-remote special purpose entity ("SPE") amended and restated the principal agreements for the T/R Facility. The amended and restated agreements add the trade receivables originated by certain U.S. and Canadian subsidiaries of the Company to the T/R Facility. Furthermore, the amended and restated agreements enable the U.S. SPE to from time to time to sell short-term trade receivables from certain customer trade accounts to PNC and the other unaffiliated purchasers on a revolving basis. The T/R Facility has a term of two years, which the Company and the U.S. SPE intend to renew. Under the T/R Facility, the Company and the other U.S. and Canadian subsidiaries continuously sell their trade receivables as they are originated to the U.S. SPE and another newly formed Canadian bankruptcy-remote special purpose entity (collectively, the “SPEs”), as applicable. None of the assets or credit of either SPE is available to satisfy the debts and obligations owed to the creditors of the Company or any other person until the obligations of the SPEs under the T/R Facility have been satisfied. The Company controls and therefore consolidates the SPEs in its condensed consolidated financial statements. As cash is collected on the trade receivables, the U.S. SPE has the ability to continuously transfer ownership and control of new qualifying receivables to PNC and the other unaffiliated purchasers such that the total outstanding balance of trade receivables sold can be up to $300 million at any point in time, which is the maximum purchase commitment of PNC and the other unaffiliated purchasers. The future outstanding balance of trade receivables that are sold is expected to vary based on the level of activity and other factors and could be less than the maximum purchase commitment of $300 million. The total outstanding balance of trade receivables that have been sold and derecognized by the U.S. SPE to PNC and the other unaffiliated purchasers is approximately $274 million as of September 30, 2021. The SPEs collectively owned $293 million (excluding the $274 million of trade receivables sold to PNC and the other unaffiliated purchasers on September 30, 2021) and $428 million of trade receivable as of September 30, 2021 and December 31, 2020, respectively, and these amounts are included in accounts receivable, net in the Company’s Condensed Consolidated Balance Sheets. Upon the amendment and restatement of the T/R Facility, the Company received an initial benefit from cash from operations of approximately $274 million in the three and nine months ended September 30, 2021, respectively. Continuous cash activity related to the T/R Facility is reflected in cash from operating activities in the condensed consolidated statement of cash flows. The U.S. SPE incurs fees due and payable to PNC and the other unaffiliated purchasers participating in the T/R Facility. Those fees, which are immaterial, are recorded within other expense, net in the condensed consolidated statements of income. In addition, each of the SPEs has provided a full recourse guarantee in favor of PNC and the other unaffiliated purchasers of the full and timely payment of all trade receivables sold to them by the U.S. SPE. The guarantee is collateralized by all the trade receivables owned by each of the SPEs that have not been sold to PNC or the other unaffiliated purchasers. The reserve recognized for this recourse obligation as of September 30, 2021 is not material. The Company, or in the case of any Canadian trade receivables, NCR Canada Corp., continues to be involved with the trade receivables even after they are transferred to the SPEs (or further transferred to PNC and the other unaffiliated purchasers) by acting as servicer. In addition to any obligations as servicer, the Company and each of its subsidiaries acting as an originator under the T/R Facility provide the SPEs with customary recourse in respect of (i) certain dilutive events with respect to the trade receivables sold to the SPEs that are caused by the Company or another originator and (ii) in the event of certain violations by the Company or another originator of their representations and warranties with respect to the trade receivables sold to the SPEs. These servicing and originator liabilities of the Company and its subsidiaries (other than the SPEs) under the T/R Facility are not expected to be material, given the high quality of the customers underlying the receivables and the anticipated short collection period.

Income Tax Disclosure [Abstract]
INCOME TAXES	7. INCOME TAXES Income tax provisions for interim (quarterly) periods are based on an estimated annual effective income tax rate calculated separately from the effect of significant, infrequent or unusual items. Income tax expense was $29 million for the three months ended September 30, 2021 compared to income tax expense of zero for the three months ended September 30, 2020. The change was primarily driven by a valuation allowance related to interest expense deduction carryforwards generated during the three months ended September 30, 2021. Additionally, during the three months ended September 30, 2021, the Company did not recognize any material discrete tax benefits, whereas during the three months ended September 30, 2020, the Company recognized discrete tax benefits resulting from a decrease in the balance of the Company's gross unrecognized tax benefits as a result of lapsing of statutes of limitations. Income tax expense was $77 million for the nine months ended September 30, 2021 compared to an income tax benefit of $33 million for the nine months ended September 30, 2020. The change was primarily driven by higher income before taxes, a valuation allowance related to interest expense deduction carryforwards generated during the nine months ended September 30, 2021 and changes in discrete tax expenses and benefits. During the nine months ended September 30, 2021, the Company recognized a $34 million expense from recording a valuation allowance against interest expense deduction carryforwards in the U.S. and a $14 million benefit from the deferred tax impact of a tax law change in the U.K. In the nine months ended September 30, 2020, the Company recognized discrete tax benefits resulting from a decrease in the balance of the Company's gross unrecognized tax benefits as a result of lapsing of statutes of limitations and a $48 million tax benefit for the release of a valuation allowance against U.S. foreign tax credits and the re-establishment of expected foreign tax credit offsets to unrecognized tax benefits. The Company engages in continuous discussions and negotiations with taxing authorities regarding tax matters, and the Company has determined that over the next 12 months it expects to resolve certain tax matters related to U.S. and foreign jurisdictions. As a result, as of September 30, 2021, we estimate that it is reasonably possible that gross unrecognized tax benefits may decrease by $5 million to $24 million in the next 12 months.

On February 23, 2021, the Company granted market-based restricted stock units with 50% of the award vesting on December 31, 2022 and 50% of the award vesting on December 31, 2023. The number of awards that vest are subject to the performance of the Company's stock price from the date of grant to December 31, 2022. The fair value was determined to be $47.20 based on using a Monte-Carlo simulation model and will be recognized over the requisite service period. The table below details the assumptions used in determining the fair value of the market-based restricted stock units. Nine months ended September 30 Dividend yield — % Risk-free interest rate 0.10 % Expected volatility 57.20 % Expected volatility for the market-based restricted stock units is calculated as the historical volatility of the Company’s stock over a period of three years, as management believes this is the best representation of prospective trends. The risk-free interest rate was determined based on a blend of the one year and two years U.S. Treasury yield curves in effect at the time of the grant. On September 22, 2021, the Company granted market-based restricted stock units with the award vesting on September 9, 2024. The number of awards that vest are subject to the performance of the Company's stock price from the date of grant to September 9, 2024. The fair value was determined to be $51.02 based on using a Monte-Carlo simulation model and will be recognized over the requisite service period. The table below details the assumptions used in determining the fair value of the market-based restricted stock units. Nine months ended September 30 Dividend yield — % Risk-free interest rate 0.47 % Expected volatility 58.47 % Expected volatility for the market-based restricted stock units is calculated as the historical volatility of the Company’s stock over a period of three years, as management believes this is the best representation of prospective trends. The risk-free interest rate was determined based on a blend of the two years and three years U.S. Treasury yield curves in effect at the time of the grant. As of September 30, 2021, the total unrecognized compensation cost of $158 million related to unvested restricted stock grants is expected to be recognized over a weighted average period of approximately 1.0 year. As of September 30, 2021, the total unrecognized compensation cost of $28 million related to unvested stock option grants is expected to be recognized over a weighted average period of approximately 0.7 years. Employee Stock Purchase Plan The Company's Employee Stock Purchase Plan (“ESPP”) provides employees a 15% discount on stock purchases using a three-month look-back feature where the discount is applied to the stock price that represents the lower of NCR’s closing stock price on either the first day or the last day of each calendar quarter. Participants can contribute between 1% and 10% of their compensation.

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	10. COMMITMENTS AND CONTINGENCIES In the normal course of business, NCR is subject to various proceedings, lawsuits, claims and other matters, including, for example, those that relate to the environment and health and safety, labor and employment, employee benefits, import/export compliance, intellectual property, data privacy and security, product liability, commercial disputes and regulatory compliance, among others. Additionally, NCR is subject to diverse and complex laws and regulations, including those relating to corporate governance, public disclosure and reporting, environmental safety and the discharge of materials into the environment, product safety, import and export compliance, data privacy and security, antitrust and competition, government contracting, anti-corruption, and labor and human resources, which are rapidly changing and subject to many possible changes in the future. Compliance with these laws and regulations, including changes in accounting standards, taxation requirements, and federal securities laws among others, may create a substantial burden on, and substantially increase costs to NCR or could have an impact on NCR's future operating results. The Company has reflected all liabilities when a loss is considered probable and reasonably estimable in the Condensed Consolidated Financial Statements. We do not believe there is a reasonable possibility that losses exceeding amounts already recognized have been incurred, but there can be no assurances that the amounts required to satisfy alleged liabilities from such matters will not impact future operating results. Other than as stated below, the Company does not currently expect to incur material capital expenditures related to such matters. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various lawsuits, claims, legal proceedings and other matters, including, but not limited to the Fox River and Kalamazoo River environmental matters and other matters discussed below, and to comply with applicable laws and regulations, will not exceed the amounts reflected in NCR’s Condensed Consolidated Financial Statements or will not have a material adverse effect on its consolidated results of operations, capital expenditures, competitive position, financial condition or cash flows. Environmental Matters NCR's facilities and operations are subject to a wide range of environmental protection laws, and NCR has investigatory and remedial activities underway at a number of facilities that it currently owns or operates, or formerly owned or operated, to comply, or to determine compliance, with such laws. Also, NCR has been identified, either by a government agency or by a private party seeking contribution to site clean-up costs, as a potentially responsible party (PRP) at a number of sites pursuant to various state and federal laws, including the Federal Water Pollution Control Act, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and comparable state statutes. Other than the Fox River matter, the Kalamazoo River matter and the Ebina matter discussed below, we currently do not anticipate material expenses and liabilities from these environmental matters. Fox River NCR is one of eight entities that were formally notified by governmental and other entities, such as local Native American tribes, that they are PRPs for environmental claims (under CERCLA and other statutes) arising out of the presence of polychlorinated biphenyls (PCBs) in sediments in the lower Fox River and in the Bay of Green Bay in Wisconsin. The other Fox River PRPs that received notices include Appleton Papers Inc. (API; now known as Appvion, Inc.), P.H. Glatfelter Company (“Glatfelter”), Georgia-Pacific Consumer Products LP (GP, successor to Fort James Operating Company), and others. NCR was identified as a PRP because of alleged PCB discharges from two carbonless copy paper manufacturing facilities it previously owned, which were located along the Fox River. NCR sold its facilities in 1978 to API. The parties have also contended that NCR is responsible for PCB discharges from paper mills owned by other companies because NCR carbonless copy paper “broke” was allegedly purchased by those other mills as a raw material. The United States Environmental Protection Agency (USEPA) and Wisconsin Department of Natural Resources (together, the Governments) developed clean-up plans for the upper and lower parts of the Fox River and for portions of the Bay of Green Bay. On November 13, 2007, the Governments issued a unilateral administrative order (the 2007 Order) under CERCLA to the eight original PRPs, requiring them to perform remedial work under the Governments’ clean-up plan for the lower parts of the river (operable units 2 through 5). In April 2009, NCR and API formed a limited liability company (the LLC), which entered into an agreement with an environmental remediation contractor to perform the work at the Fox River site. In-water dredging and remediation under the clean-up plan commenced shortly thereafter. NCR and API, along with B.A.T Industries p.l.c. (BAT), share among themselves a portion of the cost of the Fox River clean-up and natural resource damages (NRD) based upon a 1998 agreement (the Cost Sharing Agreement), a 2005 arbitration award (subsequently confirmed as a judgment), and a September 30, 2014 Funding Agreement (the Funding Agreement). The Cost Sharing Agreement and the arbitration resolved disputes that arose out of the Company's 1978 sale of its Fox River facilities to API. The Cost Sharing Agreement and arbitration award resulted in a 45% share for NCR of the first $75 million of such costs (a threshold that was reached in 2008), and a 40% share for amounts in excess of $75 million. The Funding Agreement arose out of a 2012 to 2014 arbitration dispute between NCR and API, and provides for regular, ongoing funding of NCR-incurred Fox River remediation costs via contributions, made to a new limited liability corporation created by the Funding Agreement, by BAT, API and, for 2014, API's indemnitor, Windward Prospects. The Funding Agreement creates an obligation on BAT and API to fund 50% of NCR’s Fox River remediation costs from October 1, 2014 forward; (API’s Fox River-related obligations under the Funding Agreement were fully satisfied in 2016); the Funding Agreement also provides NCR contractual avenues for payment of, via direct and third-party sources, (1) the difference between BAT’s and API’s 60% obligation under the Cost Sharing Agreement and arbitration award on the one hand and their ongoing (since September 2014) 50% payments under the Funding Agreement on the other, as well as (2) the difference between the amount NCR received under the Funding Agreement and the amount owed to it under the Cost Sharing Agreement and arbitration award for the period from April 2012 through September 2014. As of September 30, 2021 and December 31, 2020, the receivable under the Funding Agreement was approximately $54 million, respectively, and was included in other assets in the Condensed Consolidated Balance Sheet. The Company anticipates that it will collect sums related to the receivable after 2021, subject and pursuant to the terms of the Funding Agreement and related agreements. This receivable is not taken into account in calculating the Company’s Fox River net reserve. The Company's litigations relating to contribution and enforcement claims concerning the Fox River have been concluded. A proposed consent decree settlement (the CD settlement) with respect to the contribution action (a case originally filed by NCR and API) and the government enforcement action (a case originally filed by the federal and state governments against several PRPs, including the Company) was successfully negotiated by NCR and the federal and state governments and was approved on August 22, 2017 by the federal district court in Wisconsin that had been presiding over those cases. A final order of dismissal as to the Company in the contribution and government enforcement actions was subsequently entered; one party, Glatfelter, had appealed the approval of the CD settlement. On January 3, 2019, the United States lodged a proposed consent decree with the Wisconsin court, reflecting a settlement reached by the United States, Wisconsin and Glatfelter with respect to Glatfelter’s Fox River liability under the government enforcement action; a component of that settlement was withdrawal of Glatfelter’s appeal opposing the Company’s CD settlement. On March 14, 2019, the Wisconsin court approved the Glatfelter consent decree, and on April 3, 2019, Glatfelter's appeal was dismissed. The CD settlement has now resolved the remaining Fox River-related contribution and enforcement claims against the Company. The key components of the approved CD settlement include (1) the Company’s commitment to complete the remediation of the Fox River, which has now been completed; (2) the Company’s conditional agreement to waive its contribution claims against the two remaining defendants in the case, GP and Glatfelter; (3) the Company’s agreement not to appeal the trial court’s decision on divisibility of harm; (4) the Governments’ agreement to include in the settlement so-called “contribution protection” in the Company’s favor as to GP’s and Glatfelter’s contribution claims against the Company, the effect of which will be to extinguish those claims; (5) the Governments’ agreement not to pursue the Company for the Governments’ past oversight costs; and (6) the Governments’ agreement to exercise prosecutorial discretion in pursuing other parties for future oversight costs and long-term monitoring and maintenance, with the Company retaining so-called “backstop” liability in the event that the other parties fail to pay future oversight costs or to perform long-term monitoring and maintenance. Additionally, although certain state law claims by GP and Glatfelter against the Company may not be affected directly by the CD settlement, the CD settlement provides that the Company’s contribution claims against those two parties will revive if those parties attempt to assert any claims against the Company relating to the Fox River, including any state law claims. In the quarter ending September 30, 2017, the remediation general contractor commenced an arbitration against the LLC, in a dispute over contract interpretation. The hearing on this matter was completed in June 2019, and the parties submitted post-trial briefs in August 2019. The amounts claimed by the contractor range from approximately $46 million to approximately $53 million; the Company disputed the claims and contested them vigorously during the hearing. In November 2019, having rejected substantial portions of the claims, the arbitration panel awarded the contractor approximately $10 million. The Company’s indemnitors and co-obligors, described below, were responsible for the majority of the award, with the Company’s share being approximately 25% of the award. With respect to the Company’s prior dispute with API, which was generally superseded by the Funding Agreement, the Company received timely payments as they came due under the Funding Agreement. Although API filed for bankruptcy protection in October 2017, it had made all of the payments to the Company in connection with the Fox River that are required of it by the Funding Agreement. NCR's eventual remediation liability, followed by long-term monitoring expected to be performed by others, will depend on a number of factors. In establishing the reserve, NCR attempts to estimate a range of reasonably possible outcomes for each of these factors, although each range is itself uncertain. NCR uses its best estimate within the range, if that is possible. Where there is a range of equally possible outcomes, and there is no amount within that range that is considered to be a better estimate than any other amount, NCR uses the low end of the range. The significant factors include: (1) the total remaining site costs, including the costs associated with decommissioning the site, the expected cost impact of which is expected to be neutral or non-material to the Company, including long-term monitoring following completion of the clean-up, and what parties are assigned to discharge the post-clean-up tasks (as noted, the Company no longer expects to bear long-term monitoring costs); (2) total NRD for the site and the share that NCR will bear (which is now resolved as to the Company); (3) the share of clean-up costs that NCR will bear (which is resolved under the CD settlement); (4) NCR's transaction and litigation costs to defend itself to the extent additional litigation is required with respect to claims brought by the general contractor; and (5) the share of NCR's payments that BAT will bear (which is governed by the Cost Sharing Agreement and the Funding Agreement, BAT has made all of the payments requested of it, and as discussed above; API is in bankruptcy and is not presumed likely to bear further shares of NCR’s payments). With respect to NRD, in connection with a certain settlement entered into by other PRPs in 2015, the Government withdrew the NRD claims it had prosecuted on behalf of NRD trustees, including those NRD claims asserted against the Company. Calculation of the Company's Fox River reserve is subject to several complexities, and it is possible there could be additional changes to some elements of the reserve over upcoming periods, although the Company is unable to predict or estimate such changes at this time. There can be no assurance that the clean-up and related expenditures and liabilities will not have a material effect on NCR's capital expenditures, earnings, financial condition, cash flows, or competitive position. As of September 30, 2021 and December 31, 2020, the gross reserve for the Fox River matter was approximately $6 million as of both periods. As of September 30, 2021 and December 31, 2020, the net reserve for the Fox River matter was approximately $28 million as of both periods. NCR contributes to the LLC to fund remediation activities and generally, by contract, has funded certain amounts of remediation expenses in advance. As of September 30, 2021 and December 31, 2020, approximately zero remained from this funding in both periods. NCR's reserve for the Fox River matter is reduced as the LLC makes payments to the remediation contractor and other vendors with respect to remediation activities. Under a 1996 agreement, AT&T Corp. (AT&T) and Nokia (as the successor to Lucent Technologies and Alcatel-Lucent USA) are responsible severally (not jointly) for indemnifying NCR for certain portions of the amounts paid by NCR for the Fox River matter over a defined threshold and subject to certain offsets. (The agreement governs certain aspects of AT&T's divestiture of NCR and of what was then known as Lucent Technologies.) Those companies have made the payments requested of them by the Company on an ongoing basis. Kalamazoo River In November 2010, USEPA issued a “general notice letter” to NCR with respect to the Allied Paper, Inc./Portage Creek/Kalamazoo River Superfund Site (Kalamazoo River site) in Michigan. Three other companies - International Paper, Mead Corporation, and Consumers Energy - also received general notice letters at or about the same time. USEPA asserts that the site is contaminated by various substances, primarily PCBs, as a result of discharges by various paper mills located along the river. USEPA does not claim that the Company made direct discharges into the Kalamazoo River, and NCR never had facilities at or near the Kalamazoo River site, but USEPA indicated that “NCR may be liable under Section 107 of CERCLA ... as an arranger, who by contract or agreement, arranged for the disposal, treatment and/or transportation of hazardous substances at the Site.” USEPA stated that it “may issue special notice letters to [NCR] and other PRPs for future RI/FS [remedial investigation / feasibility studies] and RD/RA [remedial design / remedial action] negotiations.” In connection with the Kalamazoo River site, in December 2010 the Company, along with two other defendants, was sued in federal court by three Georgia-Pacific (GP) affiliate corporations in a private-party contribution and cost recovery action for alleged pollution. The suit, pending in Michigan, asks that the Company and other defendants pay a “fair portion” of these companies’ costs. Various removal and remedial actions remain to be decided upon and performed at the Kalamazoo River site, the total costs for which generally remain undetermined; in 2017 Records of Decisions were issued for two parts of the river, and in 2018 such a decision was issued for another part of the river, but such decisions for the majority of the work are expected to be made only over the next several years. The suit alleges that the Company is liable to the GP entities as an “arranger” under CERCLA. The initial phase of the case was tried in a Michigan federal court in February 2013; on September 26, 2013 the court issued a decision that held NCR was liable as an “arranger” as of at least March 1969. (PCB-containing carbonless copy paper was produced from approximately 1954 to April 1971, and the majority of contamination at the Kalamazoo River site had occurred prior to 1969). NCR preserved its right to appeal the September 2013 decision. In the 2013 decision, the Court did not determine NCR’s share of the overall liability. Relative shares of liability for the four companies were tried to the court in a subsequent phase of the case in December 2015. In a ruling issued on March 29, 2018, the court addressed responsibility for the costs that GP had incurred in the past, totaling to approximately $50 million (GP had sought approximately $105 million, but $55 million of those claims were removed by the court upon motions filed by the Company and other parties); NCR and GP were each assigned a 40% share of those costs, and the other two companies were assigned 15% and 5% as their allocations. The court entered a judgment in the case on June 19, 2018, in which it indicated that it would not allocate future costs, but would enter a declaratory judgment that the four companies together had responsibility for future costs, in amounts and shares to be determined. Cross-proceedings have been commenced to obtain recoveries from the other parties pursuant to the judgment; those proceedings were stayed pending the appeal referenced below. In July 2018, the Company appealed to the United States Court of Appeals for the Sixth Circuit both the 2013 court decision, which it believes is in conflict with a decision from the Fox River trial court as to Operable Unit 1 of that site and an affirmance of that decision from the Court of Appeals for the Seventh Circuit, and the 2018 court decision, on various legal grounds. The Company filed a bond to stay any execution of the judgment pending the appeal, and its application for a stay was approved by the court and remains stayed until the Company filed its dismissal of the appeal on December 31, 2020 pursuant to a Consent Decree, noted below. During the pendency of the Sixth Circuit stay, the Company negotiated a settlement of the Kalamazoo River matter with the USEPA and other government agencies having oversight over the river. On December 5, 2019, the Company entered into a Consent Decree, filed with the District Court on December 11, 2019, and on December 2, 2020, the District Court approved the Consent Decree, which has now resolved all litigation associated with the river clean-up, including the Sixth Circuit appeal. The Consent Decree requires the Company to pay GP its 40% share of past costs, to pay the USEPA and state agencies their past and future administrative costs, and to dismiss its Sixth Circuit appeal. The Consent Decree further requires the Company to take responsibility for the remediation of a portion, but not all, of the Kalamazoo River. The Consent Decree further provides the Company protection from other PRPs, including GP, seeking contribution for their costs associated with the clean-up anywhere on the river, thereby resolving the allocation of future costs left unresolved by the June 19, 2019 judgment. NCR expects to have claims against BAT and API under the Funding Agreement, discussed above for the Kalamazoo River remediation expenses. API filed for bankruptcy protection in October 2017, and thus payment of its potential share under the Funding Agreement for so-called “future sites,” which would include the Kalamazoo River site, may be at risk, but as liability under the Cost Sharing Agreement and the Funding Agreement is joint and several, the bankruptcy is not anticipated to affect the Company’s ability to seek that amount from BAT. The Company will also have indemnity or reimbursement claims against AT&T and Nokia under the arrangement discussed above in connection with the Fox River matter after expenses have met a contractual threshold set out in the 1996 agreement referenced above in the Fox River discussion. As of September 30, 2021 and December 31, 2020, the total reserve for Kalamazoo was $119 million and $164 million, respectively. That figure is reported on a basis that is net of expected contributions from the Company's co-obligors and indemnitors, subject to when the applicable threshold is reached. While the Company believes its co-obligors' and indemnitors' obligations are as previously reported, the reserve reflects changes in positions taken by some of those co-obligors and indemnitors with respect to the Kalamazoo River. The contributions from its co-obligors and indemnitors are expected to range from $70 million to $140 million and the Company will continue to pursue such contribution. As many aspects of the costs of remediation will not be determined for several years (and thus the high end of a range of possible costs for many areas of the site cannot be quantified at this time), the Company has made what it considers to be reasonable estimates of the low end of a range for such costs where remedies are identified, and/or of the costs of investigations and studies for areas of the river where remedies have not yet been determined, and the reserve is informed by those estimates. The extent of NCR’s potential liability remains subject to many uncertainties, notwithstanding the settlement of this matter and related Consent Decree noted above, particularly in as much as remedy decisions and cost estimates will not be generated until times in the future and as most of the work to be performed will take place through the 2030s. Under other assumptions or estimates for possible costs of remediation, which the Company does not at this point consider to be reasonably estimable or verifiable, it is possible that the reserve the Company has taken to discontinued operations reflected in this paragraph could more than approximately double the reflected reserve. Ebina The Company is engaged in cooperative regulatory compliance activities with the government of Japan in connection with certain environmental contaminants generated in its past operations in that country. The Company has quantities of PCB and other wastes primarily from its former plant at Oiso, Japan, including capsulated undiluted solutions manufactured in the past, capacitors, light ballasts and PCB-affected soil from the Oiso plant that was excavated and placed in steel drums. These wastes are stored in a facility at Ebina, Japan in accordance with Japanese regulations governing such materials. Over the past several years Japan has enacted and amended legislation governing such wastes, and has set a current deadline for treating and disposing of (at government-constructed disposal facilities) the highest-concentration wastes by 2027. Lower-concentration wastes can be and have been disposed of via private contractors, and as of the period ended September 30, 2021, NCR had disposed of approximately seventy percent of its lower-concentration wastes and approximately forty percent of its higher-concentration wastes. The Company and its consultants have met and communicated regularly with the Japanese agency charged with administration of the law, and are working with that agency on a program to manage disposal of the high-concentration wastes, including tests of technologies to make the disposal more efficient. The government has given its final approvals and the Company has started to dispose of the high-concentration wastes in 2021, with final deadlines for various of the government-constructed disposal sites currently set for 2022, 2023 and later. Low-concentration wastes are required to be contracted for disposal by 2027, a timetable that the Company expects to meet. In September 2019, the Company’s environmental consultants, following a series of communications and meetings with the Japanese agency, at the Company’s request prepared an estimate of remaining disposal costs over the coming several years. While the estimate is subject to a range of assumptions and uncertainties, including prospects of cost reduction in coordination with the agency as certain field testing to separate high-concentration and low-concentration waste progresses over the coming years, the Company has adjusted its existing reserve for the matter to take into account this cost estimate, and that reserve as of September 30, 2021 is $18 million compared to $20 million at December 31, 2020. The Japan environmental waste issue is treated as a compliance matter and not as litigation or enforcement, and the Company has received no threats of litigation or enforcement. Environmental-Related Insurance Recoveries In connection with the Fox River and other environmental sites, through September 30, 2021, NCR has received a combined gross total of approximately $202 million in settlements reached with various of its insurance carriers. Portions of many of these settlements agreed in the 2010 through 2013 timeframe are payable to a law firm that litigated the claims on the Company's behalf. Some of the settlements cover not only the Fox River but also other environmental sites; some are limited to either the Fox River or the Kalamazoo River site. Some of the settlements are directed to defense costs and some are directed to indemnity; some settlements cover both defense costs and indemnity. The Company does not anticipate that further material insurance recoveries specific to Kalamazoo River remediation costs will be available to it, but is currently in settlement discussions with certain carriers over amounts potentially owed to the Company. Claims with respect to Kalamazoo River defense costs have now been settled, with the amounts of those settlements included in the sum reported above. Environmental Remediation Estimates It is difficult to estimate the future financial impact of environmental laws, including potential liabilities. NCR records environmental provisions when it is probable that a liability has been incurred and the amount or range of the liability is reasonably estimable in accordance with accounting guidance, where liabilities are not expected to be quantifiable or estimable for a period of years, the estimated costs of investigating those liabilities are recorded as a component of the reserve for that particular site. Provisions for estimated losses from environmental restoration and remediation are, depending on the site, based generally on internal and third-party environmental studies, estimates as to the number and participation level of other PRPs, the extent of contamination, estimated amounts for attorney and other fees, and the nature of required clean-up and restoration actions. Reserves are adjusted as further information develops or circumstances change. Management expects that the amounts reserved from time to time will be paid out over the period of investigation, negotiation, remediation and restoration for the applicable sites. The amounts provided for environmental matters in NCR's Condensed Consolidated Financial Statements are the estimated gross undiscounted amounts of such liabilities, without deductions for indemnity insurance, third-party indemnity claims or recoveries from other PRPs, except as qualified in the following sentences. In those cases where insurance carriers or third-party indemnitors have agreed to pay any amounts and management believes that collectability of such amounts is probable, the amounts are recorded in the Condensed Consolidated Financial Statements. For the Fox River and Kalamazoo River sites, as described above, assets relating to the AT&T and Nokia indemnities and to the BAT obligations are recorded as payment is supported by contractual agreements, public filings and/or payment history. Other Matters Kristen Schertzer, et al On March 1, 2019, Cardtronics was named as a defendant in a purported class action lawsuit stylized as Kristen Schertzer, et al. v. Bank of America, N.A., et al., Case No. 3:19-cv-00264, in the United States District Court for the Southern District of California, which alleges harm related to balance inquiry transactions. On September 28, 2020, the District Court issued a denial of Cardtronics’ motion to dismiss and the matter proceeded to the discovery phase. In October 2021, Cardtronics and the putative class representative agreed to settle this matter as to the company only on an individual plaintiff basis. The litigation continues as to the other defendants. Cardtronics will soon be dismissed from the case. Guarantees and Product Warranties In the ordinary course of business, NCR may issue performance guarantees on behalf of its subsidiaries to certain of its customers and other parties. Some of those guarantees may be backed by standby letters of credit, surety bonds, or similar instruments. In general, under the guarantees, NCR would be obligated to perform, or cause performance, over the term of the underlying contract in the event of an unexcused, uncured breach by its subsidiary, or some other specified triggering event, in each case as defined by the applicable guarantee. NCR believes the likelihood of having to perform under any such guarantee is remote. As of September 30, 2021 and December 31, 2020, NCR had no material obligations related to such guarantees, and therefore its Condensed Consolidated Financial Statements do not have any associated liability balance. NCR provides its customers a standard manufacturer’s warranty and records, at the time of the sale, a corresponding estimated liability for potential warranty costs. Estimated future obligations due to warranty claims are based upon historical factors, such as labor rates, average repair time, travel time, number of service calls per machine and cost of replacement parts. When a sale is consummated, the total customer revenue is recognized, provided that all revenue recognition criteria are otherwise satisfied, and the associated warranty liability is recorded using pre-established warranty percentages for the respective product classes. From time to time, product design or quality corrections are accomplished through modification programs. When identified, associated costs of labor and parts for such programs are estimated and accrued as part of the warranty reserve. The Company recorded the activity related to the warranty reserve for the nine months ended September 30 as follows: In millions 2021 2020 Warranty reserve liability Beginning balance as of January 1 $ 18 $ 21 Accruals for warranties issued 20 22 Settlements (in cash or in kind) (20) (25) Ending balance as of September 30 $ 18 $ 18 In addition, NCR provides its customers with certain indemnification rights. In general, NCR agrees to indemnify the customer if a third party asserts patent or other infringement on the part of its customers for its use of the Company’s products subject to certain conditions that are generally standard within the Company’s industries. On limited occasions the Company will undertake additional indemnification obligations for business reasons. From time to time, NCR also enters into agreements in connection with its acquisition and divestiture activities that include indemnification obligations by the Company. The fair value of these indemnification obligations is not readily determinable due to the conditional nature of the Company’s potential obligations and the specific facts and circumstances involved with each particular agreement. The Company has not recorded a liability in connection with these indemnifications, and no current in

Leases [Abstract]
LEASING	11. LEASING Lessee We lease property, vehicles and equipment under operating and financing leases. For leases with terms greater than 12 months, we record the related asset and obligation at the present value of lease payments over the term. We determine the lease term by assuming the exercise of renewal options that are reasonably certain. Leases with a lease term 12 months or less at lease commencement are not recorded on our Condensed Consolidated Balance Sheet and are expensed on a straight-line basis over the lease term in our Condensed Consolidated Statement of Operations. Our leases may include rental escalation clauses, renewal options and/or termination options that are factored into our determination of lease payments when appropriate. When available, we use the rate implicit in the lease to discount lease payments to present value; however, most of our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate to discount the lease payments based on information available at lease commencement. Our incremental borrowing rate is based on a credit-adjusted risk-free rate at commencement date, which best approximates a secured rate over a similar term of lease. Additionally, we do not separate lease and non-lease components for any asset classes, except for those leases embedded in certain service arrangements. Fixed and in-substance fixed payments are included in the recognition of the operating and financing assets and lease liabilities, however, variable lease payments, other than those based on a rate or index, are recognized in the Condensed Consolidated Statements of Operations in the period in which the obligation for those payments is incurred. The Company’s variable lease payments generally relate to payments tied to various indices, non-lease components and payments above a contractual minimum fixed payment.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	13. EARNINGS PER SHARE Basic earnings per share (EPS) is calculated by dividing net income or loss attributable to NCR, less any dividends (declared or cumulative undeclared), deemed dividends, accretion or decretion, redemption or induced conversion on our Series A Convertible Preferred Stock, by the weighted average number of shares outstanding during the period. In computing diluted EPS, we adjust the numerator used in the basic EPS computation, subject to anti-dilution requirements, to add back the dividends (declared or cumulative undeclared), deemed dividends, accretion or decretion, redemption or induced conversion on our Series A Convertible Preferred Stock. We adjust the denominator used in the basic EPS computation, subject to anti-dilution requirements, to include the dilution from potential shares related to the Series A Convertible Preferred Stock and stock-based compensation plans. The holders of Series A Convertible Preferred Stock, unvested restricted stock units and stock options do not have nonforfeitable rights to common stock dividends or common stock dividend equivalents.

FAIR VALUE OF ASSETS AND LIABILITIES	15. FAIR VALUE OF ASSETS AND LIABILITIES Assets and Liabilities Measured at Fair Value on a Recurring Basis Assets and liabilities recorded at fair value on a recurring basis as of September 30, 2021 and December 31, 2020 are set forth as follows: September 30, 2021 In millions Total Quoted Prices in Significant Other Significant Assets: Deposits held in money market mutual funds (1) $ 8 $ 8 $ — $ — Foreign exchange contracts (2) 2 — 2 — Interest rate cap agreements (3) 8 — 8 — Total $ 18 $ 8 $ 10 $ — Liabilities: Foreign exchange contracts (4) $ 1 $ — $ 1 $ — Total $ 1 $ — $ 1 $ — December 31, 2020 In millions Total Quoted Prices in Significant Other Significant Assets: Deposits held in money market mutual funds (1) $ 22 $ 22 $ — $ — Foreign investments (2) 2 — 2 — Foreign exchange contracts (2) — — — — Total $ 24 $ 22 $ 2 $ — Liabilities: Foreign exchange contracts (4) $ 1 $ — $ 1 $ — Total $ 1 $ — $ 1 $ — (1) Included in Cash and cash equivalents in the Condensed Consolidated Balance Sheets. (2) Included in Other current assets in the Condensed Consolidated Balance Sheets. (3) Included in Other assets in the Condensed Consolidated Balance Sheets. (4) Included in Other current liabilities in the Condensed Consolidated Balance Sheets. Deposits Held in Money Market Mutual Funds A portion of the Company’s excess cash is held in money market mutual funds that generate interest income based on prevailing market rates. Money market mutual fund holdings are measured at fair value using quoted market prices and are classified within Level 1 of the valuation hierarchy. Foreign Investments The investments primarily include an investment fund similar to a mutual fund. The investments are valued using observable, either directly or indirectly, inputs for substantially the full term of the assets and are classified within Level 2 of the valuation hierarchy. Foreign Exchange Contracts As a result of our global operating activities, we are exposed to risks from changes in foreign currency exchange rates, which may adversely affect our financial condition. To manage our exposures and mitigate the impact of currency fluctuations on our financial results, we hedge our primary transactional exposures through the use of foreign exchange forward and option contracts. The foreign exchange contracts are valued using the market approach based on observable market transactions of forward rates and are classified within Level 2 of the valuation hierarchy. Interest Rate Cap Agreements In order to add stability to interest expense and operating costs and to manage exposure to interest rate movements the Company utilizes interest rate cap agreements as part of its interest rate risk management strategy. The interest rate cap agreements are valued using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. As such, the interest rate cap agreements are classified in Level 2 of the fair value hierarchy. We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we consider the impact of netting and any applicable credit enhancements. We measure the credit risk of our derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments utilize Level 3 inputs to evaluate the likelihood of both our own default and counterparty default. As of September 30, 2021, we determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives and therefore, the valuations are classified in Level 2 of the fair value hierarchy. Assets Measured at Fair Value on a Non-recurring Basis From time to time, certain assets are measured at fair value on a nonrecurring basis using significant unobservable inputs (Level 3). NCR reviews the carrying values of investments when events and circumstances warrant and considers all available evidence in evaluating when declines in fair value are other-than-temporary declines. There were no material impairment charges or non-recurring fair value adjustments recorded during the three and nine months ended September 30, 2021 and 2020.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying Condensed Consolidated Financial Statements have been prepared by NCR Corporation (NCR, the Company, we or us) without audit pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC) and, in the opinion of management, include all adjustments (consisting of normal, recurring adjustments, unless otherwise disclosed) necessary for a fair statement of the condensed consolidated results of operations, financial position, and cash flows for each period presented. The consolidated results for the interim periods are not necessarily indicative of results to be expected for the full year. The 2020 year-end Condensed Consolidated Balance Sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States (GAAP). These financial statements should be read in conjunction with NCR’s Form 10-K for the year ended December 31, 2020.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and revenue and expenses during the period reported. Although our estimates contemplate current and expected future conditions, as applicable, it is reasonably possible that actual conditions could differ from our expectations, which could materially affect our results of operations and financial position. In particular, a number of estimates have been and will continue to be affected by the ongoing novel coronavirus (COVID-19) pandemic. The ultimate impact on our overall financial condition and operating results will depend on the currently unknowable duration and severity of the pandemic, supply chain challenges and cost escalations including materials, labor and freight, and any additional governmental and public actions taken in response. As a result, our accounting estimates and assumptions may change over time as a consequence of the effects of COVID-19. Such changes could result in future impairments of goodwill, intangible assets, long-lived assets, incremental credit losses on accounts receivable and decreases in the carrying amount of our tax assets.
Evaluation of Subsequent Events	Evaluation of Subsequent Events The Company evaluated subsequent events through the date that our Condensed Consolidated Financial Statements were issued. No matters were identified that required adjustment of the Condensed Consolidated Financial Statements or additional disclosure other than subsequent events disclosed within the notes to the Condensed Consolidated Financial Statements.
Reclassifications	Reclassifications Certain prior-period amounts have been reclassified in the accompanying Condensed Consolidated Financial Statements and Notes thereto in order to conform to the current period presentation. Reclassifications had no effect on prior year net income or shareholders’ equity.
Remaining Performance Obligations	Remaining Performance Obligations Remaining performance obligations represent the transaction price of orders for which products have not been delivered or services have not been performed. As of September 30, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $3.7 billion. The Company expects to recognize revenue on approximately three-quarters of the remaining performance obligations over the next 12 months, with the remainder recognized thereafter. The majority of our professional services are expected to be recognized over the next 12 months but this is contingent upon a number of factors, including customers’ needs and schedules.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Issued In August 2020, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update with new guidance for convertible preferred stock, which eliminates considerations related to the beneficial conversion feature model. The standard also requires an average stock price when calculating the denominator for diluted earnings per share to be used for stock units where the settlement of the number of shares is based on the stock price. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early adoption is permitted no earlier than fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. The adoption of this accounting standards update is not expected to have a material effect on the Company's net income, cash flows, earnings per share or financial condition. In May 2021, the FASB issued an accounting standards update with new guidance for freestanding equity-classified written call options. The new guidance requires modifications or exchanges of freestanding equity-classified written call options that remain equity classified after the modification or exchange based on the economic substance of the modification or exchange. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted. The adoption of this accounting standards update is not expected to have a material effect on the Company's net income, cash flows, earnings per share or financial condition. Adopted
Lessor	Lessor We have various arrangements for certain point-of-sale equipment under which we are the lessor. These leases meet the criteria for operating lease classification. Lease income associated with these leases is not material.
