Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
ISO/IEC 14443-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 17, Cards and personal identification.
This second edition cancels and replaces the first edition (ISO/IEC 14443-3:2001), which has been technically
revised.
It also incorporates the Amendments ISO/IEC 14443-3:2001/Amd.1:2005 and ISO/IEC 14443-3:2001/
Amd.3:2006, and the Technical Corrigendum ISO/IEC 14443-3:2001/Amd.1:2005/Cor.1:2006.
ISO/IEC 14443 consists of the following parts, under the general title Identification cards — Contactless
integrated circuit cards — Proximity cards:
⎯ Part 1: Physical characteristics
⎯ Part 2: Radio frequency power and signal interface
⎯ Part 3: Initialization and anticollision
⎯ Part 4: Transmission protocol
