感觉数据就存储在第一扇区，可是无论咋样都没看出个所以然来，更别说日期什么的了。
然后去找了物业，补了电梯卡重新扫描得到

好像不是long或int，彻底不会了求大神指点，猜测的思路是否是二进制铭文用两个文件进行了对比
发现了年份的三种可能


由于月份确定又对二进制数据进行筛选找到可惜结果差强人意
好像并不对。
实验改旧卡：把12改为13，结果测试失败证明有验证位存在。（感谢糖哥不辞辛苦深夜还在帮我分析）

这个，看不懂！
请大神出手

我也是完全看不懂，日期就差那么一点怎么数据变化这么多0.0

f52577521

我只想默默把贴子顶起来，等着大神们回复，给各位兄弟做一个案例分析来看。

f52577521

没人看，然后自己回过神来，再默默的吧帖子顶起来，我不在的时候帖子又会偷偷的沉下去。

f52577521

待我施展顶起召唤术~~跟我默念起~~

f52577521

不想废话了~起

f52577521

起来~没有然后~

我是黑瞳

然后我发现附件还收费呢，咋弄得楼主，不会弄咧
