通过对比分析，基本分析出了楼层的位置在1扇区2区块前8个数据，已测试过改FF可用，但用锤子的楼层工具转换不到想要的楼层数据出来，也一直看不出哪里是时间位的数据和园区码的数据，现在能做到的只有通楼，想掌握修改楼层和修改时间的知识，求各位大神指点指点，付费答疑，QQ178449643

多点数据可以对比出来吗？

只能说碰运气了，会有概率能通过数据对比找到日期位置，但是如果是加密的数据，即使对比出来，恐怕也不会那么好修改，如果再加上日期带有校验码，那就更难了

请教一下日期加密了的话要怎么解密？我暂时只分析到了楼层数据的位置，日期位置一头雾水

看來日期加密了，估計也有校驗，延期費勁。

日期模糊搜索，我从23年4月1日搜索到了27年4月30日都没有，看起来这个系统应该是楼上有一位说的那样了，应该是数据加密的那种小众系统，如果是这样那这个就更不好操作了，只能通过多个卡对比，碰运气了

软件都分析不出来是什么系统，这个不大好研究了，现在卡的到期时间是否知道？
如果知道可以模糊搜索一下试 ...

物业说两年有效期，我是23年4月28日更新的，应该到期日期会是24年或者25年的4月28日，以往都是一年一更新，今次给我整了两年不知是真是假。楼层工具的数据转换也找不到规律
