各位大佬求帮忙看电梯卡数据（软件显示未知梯控56）

Ricky

各位大佬，软件分析显示未知梯控56，1扇区和9扇区有数据，目前分析1扇区应该是有效期，9扇区是可用楼层，用两张卡尝试对比了几次但是没有找到突破口，希望大佬能帮忙看下，刷卡后卡内数据没有变应该没有滚动吗，住宅是6栋605，看物业充卡软件勾选的可用楼层有1、2、3、4、6、7、26、27层

数据一：卡1，今天续期，有效期三个月（应该是到2023年12月19日23:59:59）

更新了下数据3和数据4，时间都是到当日23:59:59的，不知道大佬有思路没

数据1和数据4期限应该1样，但日期算法还是不理解，但复制未到期的卡1扇区区块就能延期
