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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/IEC JTC 1, Information technology, Subcommittee
SC 17, Cards and personal identification.
This third edition cancels and replaces the second edition (ISO/IEC 14443-2:2010), which has been
technically revised.
It also incorporates the Amendments ISO/IEC 14443-2:2010/Amd 1:2011,
ISO/IEC 14443-2:2010/Amd 2:2012 and ISO/IEC 14443-2:2010/Amd 3:2011.
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

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. It is intended to be used in conjunction with other parts of ISO/IEC 14443.
Contactless card standards cover a variety of types as embodied in ISO/IEC 10536 (close-coupled cards),
ISO/IEC 14443 (proximity cards) and ISO/IEC 15693 (vicinity cards). These are intended for operation
when very near, nearby and at a longer distance from associated coupling devices, respectively.

Part 2:
Radio frequency power and signal interface
1 Scope
This part of ISO/IEC 14443 specifies the characteristics of the fields to be provided for power and bi-
directional communication between proximity coupling devices (PCDs) and proximity cards or objects
(PICCs).
This part of ISO/IEC 14443 does not specify the means of generating coupling fields, nor the means of
compliance with electromagnetic radiation and human exposure regulations, which can vary according
to country.
