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 4 to ISO/IEC 14443-3:2010 was prepared by Joint Technical Committee ISO/IEC JTC 1,

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

Amendment 4: Handling rules of RFU bits
Page 5, Clause 4
Add new paragraph after last dash:

“For the purposes of this part of ISO/IEC 14443, the following general rule applies:

A PICC or PCD sending RFU bits shall set these bits to the value indicated herein or to (0)b if no value is

given. A PICC or PCD receiving RFU bits shall disregard the value of these bits and shall maintain and not

change its function, unless explicitly stated otherwise.”
Page 6, Clause 6
Delete second paragraph:
Page 15, 6.4.1
Delete penultimate sentence
Replace last sentence with:

“A PICC receiving a short frame containing an RFU value shall interpret this as Error (see Figure 7) and shall

not send a response.”
Page 15, 6.4.3
Replace following paragraph and NOTE:

“If the PICC responds with any modulation during a period of 1 ms after the end of the frame containing the

HLTA command, this response shall be interpreted as 'not acknowledge'.
NOTE The PCD should apply an additional waiting time margin of 0,1 ms.”

with:

“When receiving a valid HLTA command in any state, the PICC shall not respond. The PCD shall not interpret

any modulation received during a period of 1 ms after the end of the frame containing the HLTA command.”

NOTE In ACTIVE or ACTIVE* state, the PICC may respond to an invalid HLTA command.”

Replace last paragraph and NOTE with:

“A PICC receiving an RFU value should interpret it as Error (see Figure 7) and should not send a response.”

Page 20, 6.5.3.3
Replace two paragraphs after Table 8 with:

“The PCD shall set NVB only to values defined in Table 8 except that for byte counts 6 and 7 only bit count of

0 is allowed.

A PICC receiving a byte count value not specified in Table 8 (b8 to b5), or receiving a bit count value not

specified in Table 8 (b4 to b1) for byte count equal 2 to 5 or set to any value other than 0 for byte count equal

6 or 7, should interpret it as Error (see Fig
