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 and IEC shall not be held responsible for identifying any or all such patent rights.

Amendment 1 to ISO/IEC 14443-2:2015 was prepared by Joint Technical Committee ISO/IEC JTC 1,

Information technology, Subcommittee SC 17, Card and personal identification.

Amendment 1: Parameters supporting active and passive PICC
transmissions
Page 2, Clause 4
Add to the clause the following symbols:
MS1 first modulated state of the load modulation
MS2 second modulated state of the load modulation
US unmodulated state before the load modulation
Ø maximum phase drift limit of the load modulation for PICC transmission
LM, max, PICC
Ø maximum phase drift limit of the load modulation for PCD reception
LM, max, PCD
Ø initial phase of the load modulation
LM, INIT
V maximum load modulation amplitude for PICC transmission
LMA, max, PICC
VLMA, max, PCD maximum load modulation amplitude for PCD reception
Page 7, Clause 7
Replace second paragraph with:

"The PICC modifies the PCD alternating magnetic field in order to transmit data to the PCD. This modification

is called load modulation and may be achieved by passively loading the PCD alternating magnetic field with a

modulated subcarrier signal, and/or by actively contributing with its own modulated alternating field."
