标准范围
ISO/IEC 7811定义了识别卡的特征。ISO/IEC 7811-6:20 08提供了卡应执行的标准，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 7811-6:20 08规定了识别卡上的高矫顽力磁条（包括任何保护性覆盖层）、编码技术和编码字符集的要求。它包括用于波形测量的改进算法，可产生更一致的结果（从ISO/IEC 7811-6:20 01/Amd.1:20 05合并），并且增加了对信号幅度的额外要求。ISO/IEC 7811-6:20 08规定了以下内容:符合性的条件；卡的物理特性（翘曲和表面变形）和磁条区域（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征；编码规范，包括技术(F2F)、记录角度、比特密度、通量转换间隔变化和信号幅度；数据结构包括磁道格式、纠错技术的使用；编码轨道的位置。ISO/IEC 7811-6:20 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 defines the characteristics of identification cards. ISO/IEC 7811-6:2008 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 7811-6:2008 specifies requirements for a high coercivity magnetic stripe (including any protective overlay) on an identification card, the encoding technique and coded character sets. It includes a modified algorithm for waveform measurement which produces more consistent results (incorporated from ISO/IEC 7811-6:2001/Amd.1:2005), and an additional requirement has been added for signal amplitude.ISO/IEC 7811-6:2008 specifies the following:
- 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 including technique (F2F), angle of recording, bit density, flux transition spacing variation, and signal amplitude;
- the data structure including track format, the use of error correction techniques;
- the location of encoded tracks.
