Which PCI standard is focused on securing physical devices that read cardholder data?

The emphasis on securing physical devices that read cardholder data is specifically addressed by the PCI PTS (Payment Terminal Security) standard. This standard outlines security requirements for point-of-sale (POS) terminals and other payment devices used to accept cardholder data, ensuring the integrity and secure handling of card information.

The PCI PTS standard is crucial for preventing unauthorized access and ensuring that devices are tamper-resistant and capable of secure data transmission. It includes specifications for both hardware and software and mandates compliance to ensure that these devices can securely encrypt and process payment data.

The other options, while related to PCI compliance, do not specifically focus on the physical security of devices. For example, PCI DSS (Data Security Standard) covers broader data security requirements across all entities that store, process, or transmit cardholder data but does not specifically address the hardware specifications. PCI-DSS is a variation and essentially refers back to PCI DSS, thus still lacking the focus on physical devices. PCI P2PE (Point-to-Point Encryption) covers the encryption of cardholder data in transit but does not specifically focus on the devices themselves.

Therefore, PCI PTS is the standard that most directly aligns with the requirement to secure physical payment devices, making it the correct answer in this
