条形码技术是基于对已定义尺寸的条和空间的模式的识别。以条形码形式编码信息的方法有很多种，称为符号学，定义将字符转换为条形、空格模式和其他基本特征的规则称为符号学规范。ISO/IEC 15438:2006规定了条形码符号PDF417的要求。它规定了PDF417符号特征、数据字符编码、符号格式、尺寸、纠错规则、参考解码算法和一些应用参数。

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.
