其中9 扇区这里有日期和校验码
0 区块: 09 08 14 00 00 00 00 00 FF FF FF FF FF FF D4 6F
09 08 14代表2020年8月9日到期，D4 6F是对应的校验码
请问如果延期为2021年8月9日到期，对应的校验码如何进行计算，求大神给个方法！
这个能不能复制使用，怕坏了不能用，物业一星期一星期给你延期，恶心死了！

开头日期写错了，最下面是正确的！

6363?可以延期的

有没其他卡的数据，就一张不好算

我是小白一个，我给你出个招，哈哈
你借一张保安或者保洁的卡，用设备复制下就好，然后就无限复制就啥都有了。
或者找当地配钥匙的，配一个卡然后复制就好了，当地做卡的用整个城市的卡牌数据，报小区名字就可以，我都是这么弄。
技术不好学习，只能这样简单点，你要是想学技术，还要找百度老师或者RMB老师
