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 I

14、EC 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 J

In particular the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with th

16、e 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 and IEC shall not be held responsible for identifying any or all such patent rights. Details of

This fourth edition cancels and replaces the third edition (ISO/IEC 7811-2:2001), which has been technically revised. It incorporates content from any published amendments or technical corrigend

20、um since the previous edition was published. Major changes from the previous edition are as follows: Wherever possible, the same definitions, criteria and test methods are used in ISO/IEC 7811-2 and ISO/IEC 7811-6. The primary standard cards held by Q-Card are used to calibrate the manufacture of se

21、condary reference cards. Other primary standard cards held by PTB and Card testing International (CTI) are used as backup to replace cards held by Q-Card as they wear out. The supplier of secondary reference cards has changed from PTB to Q-Card During revision, some figure and table numbers may have

22、 changed and might not be the same between the two standards. Notes in this part of ISO/IEC 7811 are only used for giving additional information intended to assist in the understanding or use of the document. They do not contain provisions or requirements to which it is necessary to conform in order

23、 to claim compliance with this part of ISO/IEC 7811. ISO/IEC 7811 consists of the following parts, under the general title Identification cards Recording technique: Part 1: Embossing Part 2: Magnetic stripe Low coercivity Part 6: Magnetic stripe High coercivity Part 7: Magnetic stripe High coercivit

25、ue Part 2: Magnetic stripe Low coercivity 1 Scope ISO/IEC 7811 defines the characteristics for identification cards as defined in Clause 4 of this part of ISO/IEC 7811 and the use of such cards for international interchange. This part of ISO/IEC 7811 specifies requirements for a low coercivity magne

26、tic stripe (including any protective overlay) on an identification card, the encoding technique and coded character sets. It takes into consideration both human and machine aspects and states minimum requirements. Coercivity influences many of the quantities specified in this part of ISO/IEC 7811 bu

27、t is not itself specified. ISO/IEC 7811 provides criteria to which cards are to perform. No consideration is given within ISO/IEC 7811 to the amount of use, if any, experienced by the card prior to test. Failure to conform to specified criteria is negotiated between the involved parties. ISO/IEC 103

28、73-2 specifies the test procedures used to check cards against the parameters specified in this part of ISO/IEC 7811. NOTE Numeric values in the SI and/or Imperial measurement system in this part of ISO/IEC 7811 may have been rounded off and therefore are consistent with, but not exactly equal to, e

29、ach other. Either system may be used, but the two are not to be intermixed or reconverted. The original design was made using the Imperial measurement system. 2 Conformance A prerequisite for conformance with this part of ISO/IEC 7811 is conformance with ISO/IEC 7810. An identification card is in co

30、nformance with this part of ISO/IEC 7811 if it meets all mandatory requirements specified herein. Default values apply if no others are specified. 3 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicatio
