因为最近做项目要用到，所以亲自实践了一把，完全能够实现。

最重要的是通信方式和连接方式。Arduino板子与RC522之间是SPI通信，Arduino工作在主模式下，
RC522工作在从模式下。连接方式如下：

            Arduino                                     RC522 (工作电压3.3V)

•D5                <------------->          RST (这个脚不接貌似也可以)

•D10                <------------->          SDA (在RC522中即为CS)

•D11                <------------->          MOSI
•D12                <------------->          MISO
•D13                <------------->          SCK

代码如下：
