ISO/IEC 14443-3:2018

Cards and security devices for personal identification — Contactless proximity objects — Part 3: Initialization and anticollision

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. NOTE 1 Part of the timing of data communication is defined in ISO/IEC 14443‑2. NOTE 2 Test methods for this document are defined in ISO/IEC 10373‑6.
