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 2021 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, 2021.
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 variants of the novel coronavirus (COVID-19) pandemic, macroeconomic pressures and geopolitical challenges. 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, interest, 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 and other external factors. 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. Other than the items discussed below and within the Notes to Condensed Consolidated Financial Statements, no matters were identified that required adjustment to the Condensed Consolidated Financial Statements or additional disclosure.
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 June 30, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $3.8 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 three 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 duration is one year or less. Additionally, we do not disclose remaining performance obligations for contracts where we recognize revenue from the satisfaction of the performance obligation in accordance with the 'right to invoice' practical expedient.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adoption of New Accounting Pronouncements In August 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, with new guidance for convertible preferred stock, which eliminates considerations related to the beneficial conversion feature model. The standard also requires entities to use an average stock price when calculating the denominator for diluted earnings per share 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 was 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 did not have a material effect on the Company's net income, cash flows, earnings per share or financial condition. In May 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options, with new guidance for freestanding equity-classified written call options. The new guidance requires issuers to account for 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 did not have a material effect on the Company's net income, cash flows, earnings per share or financial condition. In March 2022, the SEC staff released Staff Accounting Bulletin No. 121 (“SAB 121”), which expressed the views of the SEC staff regarding the accounting for obligations to safeguard crypto-assets an entity holds for users of its crypto platform. This guidance requires entities that hold crypto-assets on behalf of platform users to recognize a liability to reflect the entity’s obligation to safeguard the crypto-assets held for its platform users. The liability should be measured at initial recognition and each reporting date at the fair value of the crypto-assets that the entity is responsible for holding for its platform users. The entity should also recognize an asset at the same time that it recognizes the safeguarding liability, measured at initial recognition and each reporting date at the fair value of the crypto-assets held for its platform users. SAB 121 also includes guidance on disclosures related to the Company’s safeguarding of crypto-assets. This guidance is effective from the first interim or annual period after June 15, 2022 and should be applied retrospectively to the beginning of the fiscal year to which the interim or annual period relates. The Company adopted this guidance in the interim period ending June 30, 2022; however, as the Company is not currently offering digital asset safeguarding services to its customers, the adoption of this guidance did not have an impact on the Company’s net income, cash flows, earnings per share or financial condition. Although there are several other new accounting pronouncements issued by the FASB and adopted by or effective for the Company, the Company does not believe any of these accounting pronouncements had a material impact on its consolidated financial statements. Accounting Pronouncements Issued But Not Yet Adopted In October 2021, the FASB issued accounting standards update (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, with new guidance for contract assets and contract liabilities acquired in a business combination. The new guidance requires contract assets and contract liabilities, such as deferred revenue, acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with Accounting Standard Codification (“ASC”) 606, Revenue from Contracts with Customers. Prior to the issuance of this guidance, contract assets and contract liabilities were recognized by the acquirer at fair value on the acquisition date. The accounting standards update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted and should be applied prospectively to acquisitions occurring on or after the effective date. The Company does not expect to early adopt the new accounting standards update. 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.
