National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organizat

14、ion 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,

15、ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of docume

16、nt should be noted. This document was drafted in accordance with the 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 res

19、ng URL: Foreword - Supplementary information The committee responsible for this document is ISO/IEC JTC 1, Information technology, SC 17, Cards and personal identification. This fourth edition cancels and replaces the third edition (ISO/IEC 7811-6:2008), which has been technically revised. It also i

20、ncorporates the Technical Corrigendum ISO/IEC 7811-6:2008/Cor.1:2010. 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 calib

21、rate the manufacture of secondary 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

22、and table numbers might have changed and might not be the same between the two International Standards. Changed the title of Figure 10 to Noise in signal waveform Changed 0,08 UR to 0,07 UR in Figure 10 to match text ISO/IEC 7811 consists of the following parts, under the general title Identificatio

26、lause 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 high coercivity magnetic stripe (including any protective overlay) on an identification card, the encoding technique, and coded character sets. It take

27、s 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 but is not itself specified. The main characteristic of the high coercivity magnetic stripe is its improved resistance to erasure.

28、This is achieved with minimal probability of damage to other magnetic stripes by contact while retaining read compatibility with magnetic stripes as defined in ISO/IEC 7811-2. This International Standard provides criteria to which cards are to perform. No consideration is given within this Internati

29、onal Standard 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 10373-2 specifies the test procedures used to check cards against the parameters specified in this part of ISO/IEC 7811. NOT

30、E Numeric values in the SI and/or Imperial measurement system in this part of ISO/IEC 7811 might have been rounded off and are therefore consistent with, but not exactly equal to, each other. Either system can be used, but the two are not to be intermixed or reconverted. The original design was made

31、 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 conformance with this part of ISO/IEC 7811 if it meets all mandatory requirements specified herein. Default values apply

32、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 application.
