GB/T 42756.3-2023 Cards and security devices for personal identification—Contactless proximity objects—Part 3:Initialization and anticollision
Abstract
This document specifies:
——The polling of a proximity card or object (PICC) entering the field of a proximity coupling device (PCD);
——The character format, frame, and timing of the initialization phase of communication between PCD and PICC;
——The content of the initial request and response;
——The method of detecting and selecting one of multiple PICCs for communication (anti-collision);
——Other parameters required for initialization communication between PICC and PCD;
——A method of quickly and easily selecting a PICC from multiple PICCs based on application standards;
——The ability to allow devices to switch between PICC and PCD functions and communicate with either the PCD or PICC separately. Devices with this capability are called PXDs.
The protocols and commands used by the upper layer and applications after the initialization phase are described in ISO/IEC 14443-4.
This document applies to Type A PICCs and Type B PICCs (as described in ISO/IEC 14443-2), as well as PCDs (as described in ISO/IEC 14443-2) and PXDs.
Note 1: The timing of data communication is defined in ISO/IEC 14443-2.
Note 2: The testing methods for this document are defined in ISO/IEC 10373-6.
