ISO/IEC 7811-1:2018本文件是一系列国际标准之一，这些标准描述了术语和定义条款中定义的身份证参数以及国际交换中此类身份证的使用
本文件规定了识别卡上浮雕字符的要求。浮雕字符用于通过使用压印机或通过视觉或机器读取传输数据。它同时考虑了人和机器方面，并规定了最低要求
本文件的目的是提供卡应执行的标准。本文件未考虑测试前卡片的使用量（如有）。 不符合规定标准的情况由相关方协商解决
ISO/IEC 10373-1规定了用于对照本文件中规定的参数检查卡片的测试程序
注1:本文件中SI和/或英制测量系统中的数值可能已四舍五入，且相互一致，但并不完全相等。使用任一系统都是正确的，但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
注2:ISO/IEC 7811-9定义的触觉识别标记（TIM）可位于本文件的名称和地址区域。该区域浮雕字符的布局无意干扰TIM。

ISO/IEC 7811-1:2018 This document is one of a series of International Standards describing the parameters for identification cards as defined in the terms and definitions clause and the use of such cards for international interchange.
This document specifies requirements for embossed characters on identification cards. The embossed characters are intended for transfer of data either by use of imprinters or by visual or machine reading. It takes into consideration both human and machine aspects and states minimum requirements.
It is the purpose of this document to provide criteria to which cards shall perform. No consideration is given within this document 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？1 specifies the test procedures used to check cards against the parameters specified in this document.
NOTE 1 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.
NOTE 2 Tactile Identifier Mark (TIM) defined by ISO/IEC 7811？9 can be located in the name and address area of this document. The layout of embossed characters in this area is not intended to interfere with TIM.
