使用ACR122U NFC读卡器对M1卡进行读写操作（可以读写中文）

因为项目需要，第一次接触到了ACR122U NFC读卡器（非接触式）和M1卡，首先介绍一下想要读写应该知道的基本知识。

我就根据我的理解先叙述一下：

ACR122U 是一款连机非接触式智能卡读写器，可以读写 ISO 14443-4 A 类和 B 类卡、MIFARE®卡、
ISO18092 卡以及 FeliCa 标签。由于符合 PC/SC 标准，它可以与现有的 PC/SC 应用相兼容。
作为非接触式标签与个人电脑的中间设备，ACR122U 通过 USB 端口与电脑建立连接并执行电脑发出
的指令，从而实现与非接触式标签的通信或者对外围设备（LED 指示灯或蜂鸣器）进行控制。

具体M1卡的介绍，推荐链接：https://blog.csdn.net/woniu3/article/details/51324483

M1卡里面有16（0-15）个扇区，每个扇区包含4个块，0扇区是0-3区块，1扇区是4-7区块，，，以此类推，15扇区就是60-63。

（1）其中0扇区里的0区块存储的是厂商代码，已经固化，不可更改。

（2）每个扇区的块0（除0扇区外）、块1、块2 为数据块，可用于存贮数据。数据块可作两种应用： 
用作一般的数据保存，可以进行读、写操作。 
用作数据值，可以进行初始化值、加值、减值、读值操作。

（3）每个扇区的块3 为控制块，包括了密码A、存取控制、密码B。

这个图是用破解工具读取出来的M1卡的数据。存储的是16进制的数据。
