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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
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.
International Standard ISO/IEC 14443-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information
technology, Subcommittee SC 17, Identification cards and related devices.
ISO/IEC 14443 consists of the following parts, under the general title Identification cards — Contactless integrated
circuit(s) cards — Proximity cards:
� Part 1: Physical characteristics
� Part 2: Radio frequency power and signal interface
� Part 3: Initialization and anticollision
� Part 4: Transmission protocol
Annex A of this part of ISO/IEC 14443 is for information only.

ISO/IEC 14443-2:2001(E)
Introduction
ISO/IEC 14443 is one of a series of International Standards describing the parameters for identification cards as
defined in ISO/IEC 7810 and the use of such cards for international interchange.
This part of ISO/IEC 14443 describes the electrical characteristics of two types of contactless interface between a
proximity card and a proximity coupling device. The interface includes both power and bi-directional
communication.
This part of ISO/IEC 14443 does not preclude the incorporation of other standard technologies on the card, such as
those referenced in Annex A.
Contactless card standards cover a variety of types as embodied in ISO/IEC 10536 (close-coupled cards),
ISO/IEC 14443 (proximity cards), ISO/IEC 15693 (vicinity cards). These are intended for operation when very near,
nearby and at a longer distance from associated coupling devices respectively.
The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) draw
attention to the fact that it is claimed that compliance with this part of ISO/IEC 14443 may involve the use of
patents.
ISO and IEC take no position concerning the evidence, validity and scope of this patent right.
The holders of these patent rights have assured ISO and IEC that they are willing to negotiate licences under
reasonable and non discriminatory terms and conditions with applicants throughout the world. In this respect, the
statements of the holders of patent rights are registered with ISO and IEC. Information may be obtained from:
