A.B文件为分别延期后的时间及验证码变动，

求助：改变延期后，如何计算时间验证？


下面是A.B.C文件的数据对比

另外请教下门禁卡问题
我改动前

媳妇改动后（19年直接改成20年可用）
0C 08 20 08 15 23 00 01 00 01 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

原来只要改动红色区域就可以，

媳妇改动后可以正常使用，

我的原来随便改可以用，现在改动后不行了，

最近门卫换了进出双向门，跟这有关系吗，
还是我的数据有问题了，蓝色位现在也需要变动

看数据，这个像是康拓的梯控。
如何计算校验，这个真不会呀，只会用软件计算

有朋友做过改成截止99年12月31日，但给的两个验证位同样无效。

哪位大神能帮给算算

我觉得应该让你的朋友给你发卡再延期，那样滚动码好弄

改动时间和验证位后，刷卡会两声错误提示

这不是滚动码，是校验码，刷卡数据不变动

你的卡

已测试，我的卡已可用，媳妇的未测试，应该也能用。

此方法思路正确，

就是不知道验证位跟卡号和时间位是如何异或转换计算出的，烧脑
