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.
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 ISO documents 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 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).

AMENDMENT 2: Waiting time management
Page 102, 12.1
Add the following sentence to the end of the first paragraph:
The waiting time management provides the information regarding application waiting time to the
outside world (see 12.1.3).
Page 106
Add the following new subclause after 12.1.2:
12.1.3 Waiting time management
12.1.3.1 General
The waiting time management service provides the information regarding application waiting time
depending on respective cases, e.g. each command, each operation, and each amount of data. By using
this information, an application on an IFD detects an unresponsive ICC without any negotiation, as an
alternative to using a single waiting time defined on a transmission protocol (See ISO/IEC 7816-3 and
ISO/IEC 14443-4).
The application waiting time is the maximum delay between the leading edge of a character transmitted
by an ICC and the leading edge of the previous character transmitted by an IFD.
This information is available under application waiting time management information DO‘7F75‘ in the
EF .ATR/INFO and/or in the FCI of any application DF. Table Amd.2-2 indicates four formats for this
information.
The rationale for handling the waiting time defined in ISO/IEC 7816-3 in correlation with the execution
time information by an application on an IFD is out of the scope of this document.

management information DO‘7F75‘
Tag Length Value
‘81‘ Var. Application waiting time management information in compact format
‘A1‘ Var. Application waiting time management data elements in expanded format
‘82‘ Var. Application waiting time management information in proprietary format
‘A2‘ Var. Application waiting time management data elements in proprietary format
12.1.3.2 Compact format
In compact format, an application waiting time management information consists of a command
indicator field followed by a concatenation of 2-byte application waiting time management factors. Each
bit of bits b7 to b1 indicates whether the application waiting time management factor for each command
