前一阵子做了个IC卡读写程序，可以读写SLE4442系统逻辑加密卡的，本来想在网上找一个，没找到，自己写了一个，为了让后来人可以轻松一点，所以就奉献给大家：） 注释比较少（本人的坏习惯），看起来有点累，不过建议你在自己看之前先熟悉一下SLE4442的协议。 程序是经过测试的，在我的931上工作的很好，有什么问题，发信给我 Ploto_zhu@etang.com-done a while ago, IC card reader procedures, can read and write SLE4442 encryption system logic card, and they would like to find an on-line, could not find himself writing a view to the later can easily point and so on devoted to you :) Notes relatively small (my bad habits), looks a bit tired, but I suggest you look at before their first study SLE4442 agreement. Procedures are tested, in my 931 on the good work and what problems, I wrote to Ploto_zhu@etang.com
