既然是2018年5月缴费一年，物业怎么会给你两年的有效期？除卡号外数据一样，说明没有校验，既然改明码日期无效，只能说明是验证卡号的，无解。

哦，我输入错误，是2019年5月缴费一年

自己顶一下，希望有大佬能联系我，付费延期，谢谢！另外我觉得2楼说两张卡一样就不存在校验的说法不一定对，有没有可能是最明码200601这个到期时间做校验呢？比如200601每位相加后两位倒置再转16进制是不是就是200601后面的5E呢？我修改200601为220601以后就无法用了，是因为后面两位校验出错了，当然我只是猜测，希望大佬解惑，谢谢！

别发了，解决不了的。像我这样的小白啥也不会，帮不了你，有技术的都是卡匠，是要收费的
