我的水卡,已破解密码并查询数据,卡数据中只有第2扇区0、1、2块和第3扇区0块有数据,第2、3扇区0块数据一样且刷卡后不变,第2扇区1、2块数据一致,且刷卡后同步变化。根据据此的刷卡后余额数据分析,第2 扇区第1、2块的第1、2位为余额,按照逆序十六进制记录,即:691D,逆序1D69,十六转十进制为7529; 191D ---1D19 -------7449 791C------1C79------7289 第13位为记录刷卡次数,59—5A---5B,每刷卡一次增加1。校验码没有分析出来,各位大神能否帮助分析一下,谢谢! 刷卡一次后余额 75.29 2 扇区 0 区块: 00 14 01 01 00 00 00 00 00 0030 31 31 37 33 12 1 区块: 69 1D 00 FA 00 00 13 05 03 11 24 00 59 0C 01 36 2 区块: 69 1D 00 FA 00 00 13 05 03 1124 00 59 0C 01 36 3 区块: 86 8E FD 6C 83 857F 07 88 DA FB FD F0 D8 9F A5 3 扇区 0 区块: 00 14 01 01 00 00 00 00 00 0030 31 31 37 33 12 1 区块: 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 2 区块: 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 3 区块: 86 8E FD 6C 83 857F 07 88 DA FB FD F0 D8 9F A5 刷卡二次后余额 74.49 2 扇区 0 区块: 00 14 01 01 00 00 00 00 00 0030 31 31 37 33 12 1 区块: 19 1D 00 50 00 00 13 05 05 07 0F 00 5A 0C 01 20 2 区块: 19 1D 00 50 00 00 13 05 05 070F 00 5A 0C 01 20 3 区块: 86 8E FD 6C 83 857F 07 88 DA FB FD F0 D8 9F A5 3 扇区 0 区块: 00 14 01 01 00 00 00 00 00 0030 31 31 37 33 12 1 区块: 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 2 区块: 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 3 区块: 86 8E FD 6C 83 857F 07 88 DA FB FD F0 D8 9F A5 刷卡三次次后余额72.89 2 扇区 0 区块: 00 14 01 01 00 00 00 00 00 0030 31 31 37 33 12 1 区块: 79 1C 00 A0 00 00 13 05 06 0C 0F 00 5B 0C 01 D6 2 区块: 79 1C 00 A0 00 00 13 05 06 0C0F 00 5B 0C 01 D6 3 区块: 86 8E FD 6C 83 857F 07 88 DA FB FD F0 D8 9F A5 3 扇区 0 区块: 00 14 01 01 00 00 00 00 00 0030 31 31 37 33 12 1 区块: 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 2 区块: 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 3 区块: 86 8E FD 6C 83 857F 07 88 DA FB FD F0 D8 9F A5
