CSA Preface
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
For brevity, this Standard will be referred to as CAN/CSA-ISO/IEC 14443-3 throughout.
This Standard supersedes CAN/CSA-ISO/IEC 14443-3:13 (adopted ISO/IEC 14443-3:2011).
Scope
This part of ISO/IEC 14443 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 part of ISO/IEC 14443 is applicable to PICCs of Type A and of Type B (as described in ISO/IEC 14443-2) and 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 part of ISO/IEC 14443 are defined in ISO/IEC 10373-6.
