标准范围

ISO/IEC 7811-8:20 08是定义识别卡特性的一系列国际标准之一。它提供了卡应遵守的标准，并规定了用于国际交换的此类卡的要求。它考虑了人和机器两个方面，并规定了最低要求。ISO/IEC 7811-8:20 08规定了识别卡上51.7 kA/m（650 Oe）磁条（包括任何保护性覆盖层）的要求。就矫顽力而言，该磁条介于ISO/IEC 7811-2（23.9 kA/m，300 Oe）和ISO/IEC 7811-6（最小199 kA/m，2500 Oe）之间，主要用于世界各地的酒店客房入口系统。ISO/IEC 7811-8:20 07规定了用于建立51.7 kA/m（650 Oe）介质给定值的“窗口”，主要区别在于定义窗口末端的Imin（6.5 Fr）和Imax（8 FR）值。ISO/IEC 7811-8:20 07中没有规定编码技术、规范、错误检测和轨道位置。ISO/IEC 7811-8:20 08规定一致性条件、卡的物理特性（翘曲和表面变形）和磁条面积（位置、高度和表面轮廓、粗糙度、粘附性、磨损和耐化学性）、磁条的信号幅度性能特性。编码规范、记录角度、比特密度、磁通过渡间距变化、信号幅度、数据结构（包括磁道格式）、纠错技术的使用和编码磁道的位置没有规定，但建议在适当的情况下与ISO/IEC 7811-2相同。ISO/IEC 7811-8:20 08与测试方法标准一起提供了各种类型的识别卡处理设备和系统之间的互换。

ISO/IEC 7811-8:2008 is one of a series of International Standards defining the characteristics of identification cards. It provides criteria to which cards shall perform and specifies the requirements for such cards used for international interchange. It takes into consideration both human and machine aspects and states minimum requirements.ISO/IEC 7811-8:2008 specifies requirements for a 51,7 kA/m (650 Oe) magnetic stripe (including any protective overlay) on an identification card. This magnetic stripe is between ISO/IEC 7811-2 (23,9 kA/m, 300 Oe) and ISO/IEC 7811-6 (minimum 199 kA/m, 2500 Oe) in terms of coercivity and is primarily used for hotel guest room entry systems worldwide. ISO/IEC 7811-8:2007 specifies the "window" to be used to establish given values for 51,7 kA/m (650 Oe) media, the main difference being in the I_min (6,5 F_R) and I_max (8 F_R) values which define the extremities of the window. Encoding techniques, specification, error detection, and track locations are not specified in ISO/IEC 7811-8:2007.ISO/IEC 7811-8:2008 specifies

• the conditions for conformance,
• physical characteristics for the card (warpage and surface distortions) and the magnetic stripe area (location, height and surface profile, roughness, adhesion, wear, and resistance to chemicals),
• the signal amplitude performance characteristics of the magnetic stripe.

The encoding specification, angle of recording, bit density, flux transition spacing variation, signal amplitude, data structure including track format, use of error correction techniques, and the location of encoded tracks are not specified, but are recommended to be the same as ISO/IEC 7811-2 where appropriate.ISO/IEC 7811-8:2008, together with a standard for test methods, provides for interchange between various types of identification card processing devices and systems.
