GB/T 42756.3-2023 Cards and security devices for personal identification - Contactless proximity objects - Part 3: Initialization and anticollision
1 Scope
This document describes the following:
——polling for proximity cards or objects (PICC) entering the field ofa proximity coupling device (PCD);
——the byte format, the frames and timing used during the initial phase of communication between PCDs and PICC;
——the initial Request and Answer to Request command content;
——methods to detect and communicate with one PICC among several PICC (anticollision);
——other parameters required to initialize communications between a PlCC and PCD;
——optional means to ease and speed up the selection of one PiCC among several PICC based onapplication criteria;
——optional capability to allow a device to alternate between the functions of a PiCC and a PCD tocommunicate with a PCD or a PlCC, respectively, A device which implements this capability is calleda PXD.
Protocol and commands used by higher layer's and by applications and which are used after the initialphase are described in ISO/IEC 14443-4.
This document is applicable to PICC ofType A and of Type B (as described in ISO/lEC 14443-2), to PCD (as described in ISO/lEC 14443-2 and to PXD.
Note 1: Part of the timing of data communication is defined in ISO/lEC 14443-2
Note 2: Test methods for this document are defined in ISO/IEC 10373-6.
