信息技术.存折本磁条

[中文适用范围]： 本国际标准规定了第 4 条中定义的储蓄簿上磁条的特征和位置，以及此类储蓄簿在国际交换中的使用。 本国际标准的要求提供了与国际交换系统的兼容性，使得能够在与国际交换中使用的读取身份证兼容的设备中读取带有磁条的储蓄簿并可能对其进行编码。 本国际标准规定了储蓄簿磁条（包括任何保护性覆盖层）、编码技术和编码字符集的要求。 它还规定了储蓄簿封面的特性，例如硬度、最小尺寸、表面不规则性、粗糙度以及封面材料和磁条之间的相互作用。 它考虑了人和机器方面并规定了最低要求。 矫顽力影响本国际标准中规定的许多量，但其本身并未规定。 将储蓄簿暴露在磁场中可能会破坏记录的数据。 本国际标准定义了储蓄簿的性能标准。 本国际标准没有考虑储蓄簿在测试之前所经历的使用量（如果有的话）。 不符合规定标准的，有关各方应进行协商。 ISO/IEC 10373-2 规定了用于根据本国际标准中规定的参数检查储蓄簿的测试程序。 测试方法中提到的卡应指储蓄簿。 注1：本国际标准中SI和/或英制测量系统中的数值可能已被四舍五入，因此彼此一致，但不完全相等。 可以使用任一系统，但两者不应混合或重新转换。 最初的设计是使用英制测量系统进行的。 注 2：国家系统可能使用不同的规范，例如 DIN，以及封闭系统的专有规范。 [外文原描述]： ISO/IEC 8484:2007 specifies the characteristics and location of a magnetic stripe on a savingsbook and the use of such savingsbooks for international interchange. Compatibility with international interchange systems is provided through the requirements of ISO/IEC 8484:2007, enabling a savingsbook with a magnetic stripe to be read and possibly encoded in a device that is compatible with reading identification cards used in international interchange. It takes into consideration both human and machine aspects and states minimum requirements. ISO/IEC 8484:2007 specifies requirements for a magnetic stripe (including any protective overlay) on a savingsbook, the encoding technique and coded character sets. It also specifies the characteristics of the savingsbook cover such as stiffness, minimum size, surface irregularities, roughness and interaction between the cover material and the magnetic stripe. Most of the magnetic characteristics are based on ISO/IEC 7811-2. The major changes from ISO 8484:1987 include the following. ISO/IEC 8484:2007 uses the same definitions, criteria and test methods as in ISO/IEC 7811-2. The reference material has changed from SRM 3200 to RM 7811/2. More complete requirements have been added for signal amplitude, flux transition spacing variation, magnetic stripe area surface profile and warpage. Classifications have been added for unused and returned savingsbooks. An optional high coercivity magnetic stripe has been added based on ISO/IEC 7811-6 and RM 7811/6. Because savingsbooks are generally paper-based documents, some criteria and test methods have been taken from ISO/IEC 15457-2. ISO/IEC 8484:2007 specifies the conditions for conformance;physical characteristics for the savingsbook (warpage, surface distortions, and stiffness) and the magnetic stripe area (location, height and surface profile, roughness, adhesion, wear, and resistance to environment),the signal amplitude performance characteristics of the magnetic stripe;the encoding specification, including technique, angle of recording, bit density, flux transition spacing variation, and signal amplitude;the data structure, including track format, coded character sets and use of error correction;the location of the encoded track. ISO/IEC 8484:2007, together with a standard for test methods, provides for interchange between various types of savingsbook processing devices and systems.
