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.
ISO/IEC 7816-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 17, Cards and personal identification.
This third edition cancels and replaces the second edition (ISO/IEC 7816-3:1997), which has been technically
revised. It also incorporates the Amendment ISO/IEC 7816-3:1997/Amd.1:2002.
In addition, it incorporates
material extracted from the first edition of Part 4 (ISO/IEC 7816-4:1995), so that the
transmission protocols are no longer present in the second edition of Part 4 (ISO/IEC 7816-4:2005).
ISO/IEC 7816 consists of the following parts, under the general title Identification cards — Integrated circuit
cards:
⎯ Part 1: Cards with contacts — Physical characteristics
⎯ Part 2: Cards with contacts — Dimensions and location of the contacts
⎯ Part 3: Cards with contacts — Electrical interface and transmission protocols
⎯ Part 4: Organization, security and commands for interchange
⎯ Part 5: Registration of application providers
⎯ Part 6: Interindustry data elements for interchange
⎯ Part 7: Interindustry commands for Structured Card Query Language (SCQL)
⎯ Part 8: Commands for security operations
⎯ Part 9: Commands for card management
⎯ Part 10: Cards with contacts — Electronic signals and answer to reset for synchronous cards
⎯ Part 11: Personal verification through biometric methods
⎯ Part 12: Cards with contacts — USB electrical interface and operating procedures
⎯ Part 13: Commands for application management in multi-application environment
⎯ Part 15: Cryptographic information application

Introduction
ISO/IEC 7816 is a series of standards specifying integrated circuit cards and the use of such cards for
interchange. These cards are identification cards intended for information exchange negotiated between the
outside world and the integrated circuit in the card. As a result of an information exchange, the card delivers
information (computation result, stored data), and/or modifies its content (data storage, event memorization).
Five parts are specific to cards with galvanic contacts and three of them specify electrical interfaces.
⎯ ISO/IEC 7816-1 specifies physical characteristics for cards with contacts.
⎯ ISO/IEC 7816-2 specifies dimensions and location of the contacts.
⎯ ISO/IEC 7816-3 specifies electrical interface and transmission protocols for asynchronous cards.
NOTE The first and second editions of ISO/IEC 7816-3 specified an optional use of contact C6 to provide the
card with programming power required to write or to erase internal non-volatile memory. As every card manufactured
since 1990 internally generates programming power, this third edition deprecates this use, as well as the related
indications in the Answer-to-Reset and the related controls in each transmission protocol.
⎯ ISO/IEC 7816-10 specifies electrical interface and answer to reset for synchronous cards.
⎯ ISO/IEC 7816-12 specifies electrical interface and operating procedures for USB cards.
All the other parts are independent of the physical interface technology. They apply to cards accessed by one
or more of the following methods: contacts, close coupling and radio frequency.
⎯ ISO/IEC 7816-4 specifies organization, security and commands for interchange.
⎯ ISO/IEC 7816-5 specifies registration of application providers.
⎯ ISO/IEC 7816-6 specifies interindustry data elements for interchange.
⎯ ISO/IEC 7816-7 specifies commands for structured card query language.
⎯ ISO/IEC 7816-8 specifies commands for security operations.
⎯ ISO/IEC 7816-9 specifies commands for card management.
⎯ ISO/IEC 7816-11 specifies personal verification through biometric methods.
⎯ ISO/IEC 7816-13 specifies commands for application management in multi-application environment.
⎯ ISO/IEC 7816-15 specifies cryptographic information application.
ISO/IEC 10536
[3]
specifies access by close coupling. ISO/IEC 14443
[5]
and ISO/IEC 15693
[6]
specify access by
radio frequency. Such cards are also known as contactless cards.
