D8M1能够对MIFARE块读写操作。支持1K，4K。

检验KEY后返回SAK，QTAQ，UID。基于D8读卡器提供的dcrf32.dll开发。

D8型IC卡读写器是开发IC卡相关产品及系统集成必备的前端处理设备。可读写双界面射频智能卡或单独的非接触式射频卡，通过RS232串行接口或USB口实现同PC机及相关设备的连接，USB採用无驱技术。可方便用户的安装使用，它对多卡的支持可用于安全发卡及那些安全要求较高的领域须要。

核心代码例如以下：

void CD8M1Dlg::Show(CString str)
{time = CTime::GetCurrentTime();CString strTime = time.Format("%H:%M:%S");int len = editShow.GetWindowTextLength();editShow.SetSel(len, len);editShow.ReplaceSel(strTime + " ----> " + str + _T("\r\n"));
