12、EC 7816-12:20052008 iv ITIC 2008 All rights reserved 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
13、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-gove
14、rnmental, 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
15、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 vo
16、te. 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 tech
17、nology, 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
18、 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

20、 procedures Part 15: Cryptographic information application ISO/IEC 105362 specifies access by close coupling. ISO/IEC 144433 and 156934 specify access by radio frequency. Such cards are also known as contactless cards. INCITS/ISO/IEC 7816-12:20052008 ITIC 2008 All rights reserved v Introduction ISO/
21、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,
22、 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 wit
23、h 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 electrica
24、l 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
25、 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/IE
26、C 7816-11 specifies personal verification through biometric methods. ISO/IEC 7816-15 specifies cryptographic information application.
