使用ACR122UNFC读卡器对M1卡进行读写操作(可以读写中文)

使⽤ACR122UNFC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：

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。
