PTS stands for PIN Transaction Security, a set of modular evaluation requirements for PIN acceptance POI terminals.

• A. PVV
• B. Protocol
• C. PTS
• D. Private Network

Answer: (C)

PIN Transaction Security is the PCI standard that governs how PIN entry and handling are secured on payment devices. It defines modular evaluation requirements for PIN acceptance point-of-interaction terminals, ensuring that PIN entry is conducted securely, PIN data is encrypted, and tamper-resistant hardware and proper key management are in place. This makes it the best fit because it names the specific security framework used for PIN entry devices.

PVV is a PIN verification value used in some offline PIN schemes, not the name of the security standard. Protocol is a general term for communication rules and doesn’t name a security program, and Private Network isn’t related to the PIN security certification framework.
