Cards and security devices for personal identification – Contactless proximity objects – Part 3 : Initialization and anticollision
OVERVIEW
This document describes the following:
— polling for proximity cards or objects (PICCs) entering the field of a proximity coupling device (PCD);
— the byte format, the frames and timing used during the initial phase of communication between PCDs and PICCs;
— the initial Request and Answer to Request command content;
— methods to detect and communicate with one PICC among several PICCs (anticollision);
— other parameters required to initialize communications between a PICC and PCD;
— optional means to ease and speed up the selection of one PICC among several PICCs based on application criteria;
— optional capability to allow a device to alternate between the functions of a PICC and a PCD to communicate with a PCD or a PICC, respectively. A device which implements this capability is called a PXD.
Protocol and commands used by higher layers and by applications and which are used after the initial phase are described in ISO/IEC 14443-4.
This document is applicable to PICCs of Type A and of Type B (as described in ISO/IEC 14443-2), to PCDs (as described in ISO/IEC 14443-2) and to PXDs.
