标准摘要
[中文适用范围]： 本国际标准规定了称为 PDF417 的条形码符号体系的要求。 它规定了PDF417符号体系特征、数据字符编码、符号格式、尺寸、纠错规则、参考解码算法和许多应用参数。 [外文原描述]： The technology of bar coding is based on the recognition of patterns of bars and spaces of defined dimensions. There are various methods of encoding information in bar code form, known as symbologies, and the rules defining the translation of characters into bars and space patterns and other essential features are known as the symbology specification. ISO/IEC 15438:2006 specifies the requirements for the bar code symbology known as PDF417. It specifies PDF417 symbology characteristics, data character encodation, symbol formats, dimensions, error correction rules, reference decoding algorithm, and a number of application parameters.
