This International Standard requires implementations to enter the selected communication mode as specified in the respective International Standard. The communication mode specifications, however, are outside the scope of this International Standard.

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.Attention is
drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO
shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 21481 was prepared by Ecma International (as ECMA-352) and was adopted, under a special “fast-
track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its
approval by national bodies of ISO and IEC.
This second edition cancels and replaces the first edition (ISO/IEC 21481:2005), which has been technically revised.

Introduction
In 2002, Ecma International formed Task Group 19 of Technical Committee 32 to specify Near Field
Communication (NFC) signal interfaces and protocols. The NFC devices are wireless closely coupled devices
communicating at 13,56 MHz.
Although ISO/IEC 18092 (NFCIP-1), ISO/IEC 14443 and ISO/IEC 15693 all specify 13,56 MHz as their
working frequency, they specify distinct communication modes. These are defined as NFC, PCD, and VCD
communication modes, respectively.
This International Standard (NFCIP-2) specifies the mechanism to detect and select one communication mode
out of those three possible communication modes. Furthermore, NFCIP-2 requires that subsequent behaviour
be as specified in the standard specifying the selected communication mode.
In 2009, JTC 1/SC 6 and JTC 1/SC 17 studied together for improving interoperability between ISO/IEC 21481
and ISO/IEC 14443. This second edition of ISO/IEC 21481 is revised based on the study, and the PICC mode
is added to the existing three modes.

1 Scope
ISO/IEC 18092, ISO/IEC 14443 and ISO/IEC 15693 specify the radio frequency signal interface, initialization,
anti-collision and protocols for wireless interconnection of closely coupled devices and access to contactless
integrated circuit cards operating at 13,56 MHz.
This International Standard specifies the communication mode selection mechanism, designed not to disturb
any ongoing communication at 13,56 MHz, for devices implementing ISO/IEC 18092, ISO/IEC 14443 or
ISO/IEC 15693. This International Standard requires implementations to enter the selected communication
mode as specified in the respective International Standard. The communication mode specifications, however,
are outside the scope of this International Standard.
2 Conformance
Conforming devices implement mode selection specified in Clause 7 and implement the NFC mode, PCD mode,
VCD mode, and PICC mode.
