可以通楼，通小区，延期，你这个月24号就到期了.
通小区+延期数据

大神，我昨天想到3点多，也没想明白为什么9扇区0块 BB2C要改成CC26呢？求大神指点一二，感激不尽

BB是功能位，CC是控制位，如果不改的话你通楼刷卡全层都会亮灯

不懂就要问，是不是我们小区的卡，除了秘钥，按照您给的数据，都可以实现通卡呢？

因为我试了一下，校验位不会根绝卡号或者卡密的变动而变动。这样的话，小区的卡，都是发的卡，一卡一密应该是算好了的，改大佬给的数据感觉理论上套到任何一个我们小区的卡上都能实现通卡得呀

效验可没这么简单哦，有的和用户编码，日期，发卡号，楼层信息有关联

这个就设计到算法了吧，大佬。目前我手里这三张我们小区的卡，9扇区0块都是反字节和，10扇区的校验位也能通过软件算出来，这种情况下其他数据按照您给的数据改，可否实现通卡呢？我特别想试一下，但是目前手里三张卡都有人再用，我怕试坏了还得去物业 手动苦笑

一会下班回家我发一下另一张卡的原始数据和我的改法，大佬帮忙看一下可行不，感激不尽。

我给你发张卡，你先试试，发卡可以的话就直接发卡，就不用改别人的卡了

你说的数据没变动是什么意思啊，电梯没反应嘛？大神给的数据一般都好用啊，你知不知道你的到期时间是哪天 ...

刷电梯时响两短声   正常的话就只响一声 响两声之后   在看数据就是没有变     这张到期 的是子好像是1130号吧
