由于每个厂家生产二代证读写器都不一样，都有自己的开发接口，这样就导致了购买了不同厂家的读写器后，要重新进行二次开发，很浪费资源，但是读写器的芯片却是通用的，都是公安部提供的，也就意味着有通用的库。该通用二代身份证delphi开发源码适用于任何厂家的任何读写器，而且自持C# Delphi等多种开发语言。(Are not the same, because each manufacturer to produce the second generation ID card reader interface has its own development, and thus lead purchased from different manufacturers reader for secondary development, is a waste of resources, but read and write on chip but are generic and are provided by the Ministry of Public Security, which means have a common library. The Universal delphi source development of second-generation ID card applies to any manufacturer of any reader, and self-sustaining multiple development languages ​ ​ such as C# Delphi.)
