今天早上532到了，读了一下自己小区的电梯卡，结果第一张卡就给我搞个这么难得滚码，研究这东西，纯属个人爱好，但这上来就给我个下马威啊。正体：
小区大门门禁+梯控，84栋 2单元 11楼，刷卡自动亮
到期时间2020年12月24日左右？
第一次接触就接触了个滚码，还带效验。
想请教一下大神，我这个卡，除了发卡，能通过修改达到通楼、通小区、延期其中任意一项效果吗？

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

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

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。

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
