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 3 to ISO/IEC 14443-2:2010 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 17, Cards and personal identification

Add new subclause after Figure 9:
“8.1.2.3 Modulation for bit rates of fc/8, fc/4 and fc/2
See 9.1.2.”

Page 14, 8.1.3
Add the following new subclause title below the 8.1.3 title:
“8.1.3.1 Bit representation and coding for bit rates of fc/128, fc/64, fc/32 and fc/16”

Add following new subclause before 8.2:
“8.1.3.2 Bit representation and coding for bit rates of fc/8, fc/4 and fc/2
Bit representation and coding is defined in 9.1.3.
Start of communication is defined in ISO/IEC 14443-3:2011, 7.1.4.
End of communication is defined in ISO/IEC 14443-3:2011, 7.1.5.”
