射频卡读卡程序,射频IC卡识别技术，通常由载有密码的射频IC卡来代替传统的键盘密码。读卡模块读出密码后，即产生输出电信号，继而驱动执行机构动作，或将密码（如卡号）送给外围对接设备（如电脑或单片机等）。采用射频卡读卡模块及感应体构成的特定系统中，因射频卡内码信号唯一且不可复制，因此射频卡不仅杜绝了非法复制密码，还为各种控制采用信息化管理创造了条件。-RF card reader procedure, radio frequency identification technology IC cards, usually containing the password from the RF IC cards to replace the traditional keyboard password. Reader module read out a password, as a result, the output signal, and then drive the implementation agency action, or passwords (such as logging) gave the external docking equipment (such as computer or microcontroller, etc.). RF card reader module consisting of sensors and the specific system, RF signal code card but not the only copy, RF Card not only prevents illegal copying passwords, but also controls the use of information management to create the conditions.
