Cards and security devices for personal identification — Contactless proximity objects — Part 2: Radio frequency power and signal interface

This document 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 document does not specify the means of generating coupling fields, nor the means of compliance with electromagnetic radiation and human exposure regulations, which can vary depending on the country.

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.
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) or the IEC
list of patent declarations received (see http:// patents .iec .ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 17, Cards and security devices for personal identification.
This fourth edition cancels and replaces the third edition (ISO/IEC 14443-2:2016), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— amendment of active and passive PICC transmissions;
— amendment of electromagnetic disturbance levels for all PICC classes.

Introduction
ISO/IEC 14443 (all parts) is one of a group 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 document 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 the ISO/IEC 14443 series.
Contactless card standards cover a variety of types as embodied in ISO/IEC 10536 (all parts) (close-
coupled cards), ISO/IEC 14443 (all parts) (proximity cards), and ISO/IEC 15693 (all parts) (vicinity
cards). These are intended for operation when very near, nearby and at a longer distance from
associated coupling devices, respectively.
