22、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
23、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
24、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 jo
25、int 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 right
26、s. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 7811-6 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 editio
27、n (ISO/IEC 7811-6:2001). It also incorporates the Amendment ISO/IEC 7811-6:2001/Amd.1:2005. The major changes from the second 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 algorithm defined in Figure 7 of
28、 ISO/IEC 7811-6:2001 has been changed to produce more consistent results (incorporated from ISO/IEC 7811-6:2001/Amd.1:2005). NOTE The requirements given in ISO/IEC 7811-4:1995 and ISO/IEC 7811-5:1995 were moved to Part 6 in the second edition. Notes in this part of ISO/IEC 7811 are only used for giv
29、ing 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 to claim compliance with this part of ISO/IEC 7811. ISO/IEC 7811 consists of the following parts, under the general t

32、 reserved 1Identification cards Recording technique Part 6: Magnetic stripe High 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
33、 specifies requirements for a high coercivity magnetic 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 q
34、uantities specified in this part of ISO/IEC 7811 but is not itself specified. The main characteristic of the high coercivity magnetic stripe is its improved resistance to erasure. This is achieved with minimal probability of damage to other magnetic stripes by contact while retaining read compatibil
35、ity with magnetic stripes as defined in ISO/IEC 7811-2. 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 should be negotiated betwe
36、en the involved parties. ISO/IEC 10373-2 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 consiste
37、nt with, but not exactly equal to, each other. Either system may be used, but the two should not 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 7
38、810. An identification card is in conformance 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 referenced documents are indispensable for the application of this document. For
