求助大神，这套数据怎么通层？

Qwer909

此卡用作：小区门禁，单元门禁，电梯卡（一个单元有两部电梯、都可刷）。
初步分析：
01~05扇区应该是门禁。

08~11扇区应该是梯控，多次刷卡没有发现滚动码。
8区0块13~15字节应该是到期时间(25年03月26日)、16字节可能是校验位。
9区2块前8字节与后8字节一致，应该分别是电梯1的楼层、电梯2的楼层(刷卡自动亮4层)。

尝试过修改为另一个楼层，也试过楼层数据改全0、全F，修改后刷卡无效、电梯发出滴滴两声。

多找几个数据对比分析

新小区，同单元还没发现有人，物业只给本楼层的卡

songwh

8区0块13--15 1A0319 时间25-3-26
9区21块1--8 0800000000000000 楼层 4
9区21块91--16 0800000000000000 楼层 4（应该分别对应两部电梯）
8区0块2 8区0块16 9区0块1-4均为滚动码，可以多次刷梯对照一下

8区0块13--15 1A0319 时间25-3-26
9区21块1--8 0800000000000000 楼层 4
9区21块91--16 0800000000000000  ...

日期、时间能看出来但是不能改，微小改动卡就失效
实测两部电梯来回刷，理论存在的滚动码没有任何变化

只有刷单元门门禁的时候，4区0块有变化
