Definitions

  1. The protection of point-of-sale terminals, payment flows, attached devices, and backend systems against card theft, malware, tampering, and fraud. POS security combines physical protection, network isolation, device management, payment encryption, and monitoring because retail systems are popular targets for data theft.

    In plain English: Security for checkout and payment terminal systems.

    Example: "The chain improved POS security by segmenting terminal networks and locking down remote maintenance software."
