ISO/IEC 7811-2:2018 识别卡 记录技术 第2部分：磁条：低矫顽磁性

标准编号：ISO/IEC 7811-2:2018

中文名称：识别卡 记录技术 第2部分：磁条：低矫顽磁性

英文名称：Identification cards — Recording technique — Part 2: Magnetic stripe: Low coercivity

发布日期：2018-08

标准范围

ISO/IEC 7811-2:20 18定义了本文件第4条中定义的识别卡的特征以及此类卡在国际交换中的使用。本文件规定了识别卡上低矫顽力磁条（包括任何保护性覆盖层）的要求、编码技术和编码字符集。它考虑了人和机器两个方面，并规定了最低要求。矫顽力影响本文中指定的许多量，但其本身没有指定。ISO/IEC 7811提供了卡的性能标准。ISO/IEC 7811中未考虑测试前卡的使用量（如果有）。不符合规定标准的情况由相关各方协商。ISO/IEC 10373-2规定了用于根据本文档中规定的参数检查卡的测试程序。注:本文档中SI和/或英制测量系统中的数值可能已四舍五入，并且彼此一致，但不完全相等。使用任何一种系统都是正确的，但是混合或重新转换值可能会导致错误。最初的设计是使用英制测量系统进行的。

ISO/IEC 7811-2:2018 defines the characteristics for identification cards as defined in Clause 4 of this document and the use of such cards for international interchange.
This document specifies requirements for a low 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 quantities specified in this document but 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 10373-2 specifies the test procedures used to check cards against the parameters specified in this document.
NOTE Numeric values in the SI and/or Imperial measurement system in this document may have been rounded off and are consistent with, but not exactly equal to each other. Using either system is correct but intermixing or reconverting values can result in errors. The original design was made using the Imperial measurement system.
