不同机具的通用的第二代居民身份证读写
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。
本类仅仅提供读卡的用法，写卡的方式我并没有写在里面，但是，相应的写调用我已经声明在里面，希望各位大侠能独自研究应用。
该类接口具有如下特点：
1、通用于目前市场上各个机具厂商的二代证读（写）机具。（想想，为不同厂商开发不同的接口确实令人头疼的，且由于接口不兼容，容易被客户骂死！
）
2、自动适应串口、USB口的各种机具
3、能读文字信息，但是，要想正确读照片，必须需要机具厂商的授权文件Termb.Lic，且授权文件必须放在C盘根目录下。（我总不能不照顾机具厂商的利益吧
）
4、除了上面第三条之外，您甚至不用安装机具的驱动程序，接上二代证机具即可使用。
废话少说，下面看实现方法：
