ISO/IEC 14443-4:2018
Cards and security devices for personal identification — Contactless proximity objects — Part 4: Transmission protocol
This document specifies a half-duplex block transmission protocol featuring the special needs of a contactless environment and defines the activation and deactivation sequence of the protocol.
This document is intended to be used in conjunction with other parts of ISO/IEC 14443 and is applicable to proximity cards or objects of Type A and Type B.
