Which PCI standard applies to a merchant using a validated PCI P2PE solution?

In the context of a merchant using a validated PCI Point-to-Point Encryption (P2PE) solution, the PCI P2PE standard is the most relevant and applicable standard. This standard specifically outlines the requirements for encryption solutions that securely transmit payment card data from the point of entry (for example, a card reader) to the payment processor. The goal of PCI P2PE is to reduce the risk of cardholder data being compromised during transmission and to simplify PCI compliance for merchants implementing these solutions.

By adhering to the PCI P2PE standard, a merchant ensures that they are using a validated solution that meets stringent security requirements for protecting sensitive payment card information. This direct association with the P2PE standard sets it apart from other options, which may serve different aspects of payment security.

For instance, while PCI DSS (Payment Card Industry Data Security Standard) is crucial for all merchants processing card data, it encompasses a wider range of security practices beyond just encryption technologies. PCI PTS (PIN Transaction Security) focuses more on secure devices used for PIN entry, and PCI HSM (Hardware Security Module) addresses secure management of cryptographic keys used in various encryptions. Therefore, when considering the specific context of using a validated PCI P2PE solution
