如标题所述，我在进行Windows 上的智能卡交互系统的研发。

此问题是出现在了连接过程中，如下代码所示：

CardTerminal card =c.connect("T=0");

解决办法：

//将T=0协议换成* ，意思是说让系统自动寻找合适的协议
CardTerminal card =c.connect("*");

如果想了解原因所在，那么继续往下翻。

具体错误信息如下：

具体原因是在于这里：

Caused by: sun.security.smartcardio.PCSCException: SCARD_E_PROTO_MISMATCH

其实， “SCARD_E_PROTO_MISMATCH” 的意思是表明该卡不支持您正在使用的协议，说到这里相信你就应该明白了，因为Java和Windows的本机智能卡API之间的接口可能不允许（或实现）强制执行特定协议，而且在SLE-4428卡上找到的数据表似乎没有提到卡支持的协议。
