This FAQ has been updated in consideration of changes to payment environments and standards, including the PCI P2PE Standard.

Use of encryption in a merchant environment does not remove the need for PCI DSS in that environment. The merchant environment is still in scope for PCI DSS due to the presence of cardholder data. For example, in a card-present environment, merchants have physical access to the payment cards in order to complete a transaction and may also have paper reports or receipts with cardholder data. Similarly, in card-not-present environments, such as mail-order or telephone-order, payment card details are provided via channels that need to be evaluated and protected according to PCI DSS.

Encryption of cardholder data with strong cryptography is an acceptable method of rendering the data unreadable in orderaccording to meet PCI DSS Requirement 3.4.3.5.1. However, encryption alone mayis not be sufficientinsufficient to render the cardholder data out of scope for PCI DSS.

related a third party receives and/or stores only data encrypted by another entity, and where they do not have the ability to decrypt the data, the third party may be able to consider the encrypted data out of scope if certain conditions are met.
