公安部已经大规模在全国范围内推广第二代居民身份证的换发工作，目前，许多地区二代证换发工作已经进行了很久。但是，相对应于二代证的推广，社会上许许多多的应用系统都还没有对二代证读卡开发相应的接口，为此，我写了一个通用的二代证机具读卡类，希望能对各位在各自的系统中开发这样的接口提供帮助。-Ministry of Public Security has a large scale across the country to promote the second-generation residents of the ID card replacement job, at present, many parts of the second generation card renewal work has been carried out for a long time. However, the relative should be the promotion of second-generation card, social applications on many systems are not yet on the development of second-generation card reader interfaces, to that end, I wrote a generic category of second-generation card reader equipment, I hope you can at their respective systems to develop this interface to help.
