    1,标签读写
    Ndef ndef = Ndef.get(tag);//如果ndef为空表示不支持该格式
    //可进行格式 如果格式化失败则不能只能换个方式
    2,M1 扇区读写

    3,CPU卡 读写
    NfcCpuUtilsnfc = new NfcCpuUtils(IsoDep.get(tag));
    }
    }

    2,扇区读写
    M1扇区默认是没有密码的,但有部分人闲不住要把密码改了,因此认证过程要加密码,一般认证KeyA就行。普通卡16个扇区64块,第一个扇区等闲不能操作。每个扇区4块,从0数起,第二扇区第一块索引就是8,每个扇区前3块存数据最后一块一般存密码。实例代码读的是2扇区8块。

    /**
    * 扇区写

    * @param sectorIndex 扇区索引 一般16个扇区 64块
    * @return

    3 CPU卡读写 重头戏
    先直接上代码,看完代码在说吧,搞这个有点心力疲惫。
    下面是一个写的完全流程,if的嵌套我承认有点low,但有助于流程理解。
    这里要说下外部认证过程:
    devices -----获取4字节随机数---------------------> cpu 卡
    devices <--------随机数+90 00--------------------- cpu 卡
    四个字节随机数+四个字节0 使用密钥进行DES加密,如果是8个随机数DES3加密。
    将命令00 82 00 00 08 以及加密后的随机数取前8位 7f cf 90 a0 5b 9c f1 73发送
    devices ----00 82 00 00 08 7f cf 90 a0 5b 9c f1 73–>cpu 卡
    devices <------------- 90 00---------------------------- cpu 卡
