Identification cards - Integrated circuit cards — Part 12: Cards with contacts — USB electrical interface and operating procedures
ISO/IEC 7816-12:2005 specifies the operating conditions of an integrated circuit card that provides a USB interface. An integrated circuit card with a USB interface is named USB-ICC. ISO/IEC 7816-12:2005 specifies the electrical conditions when a USB-ICC is operated by an interface device - for those contact fields that are not used, when the USB interface is applied; the USB standard descriptors and the USB-ICC class specific descriptor; the data transfer between host and USB-ICC using bulk transfers or control transfers; the control transfers which allow two different protocols named version A and version B; the (optional) interrupt transfers to indicate asynchronous events; status and error conditions. ISO/IEC 7816-12:2005 provides two protocols for control transfers. This is to support the protocol T=0 (version A) or to use the transfer on APDU level (version B). ISO/IEC 7816-12:2005 provides the state diagrams for the USB-ICC for each of the transfers (bulk transfers, control transfers version A and version B). Examples of possible sequences which the USB-ICC must be able to handle are given in an informative annex.

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.
ISO/IEC 7816-12 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 17, Cards and personal identification.
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

ISO/IEC 10536 specifies access by close coupling. ISO/IEC 14443 and 15693 specify access by radio
frequency. Such cards are also known as contactless cards.

Introduction
ISO/IEC 7816 is a series of documents 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.
• 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 from the physical interface technology. They apply to cards accessed
by contacts and / or by 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 7816-15 specifies cryptographic information application.
