任意复制卡片的话,不会冲突吗? 比如多个卡片信息都存在同一扇区

仔细看一下硬件工程文件,简单地说目前IC卡的信息是存在每个单独的UID芯片(很便宜大概1~2元一个)上的,ST25有两个作用,一个是能量采集,一个是负责作为手机和MCU通信的桥梁(NFC-PHY);也就是可以理解为L-ink里面是有多个芯片,共用一个线圈,靠开关切换。之所以这么设计,是因为ST25DV支支持ISO 15693协议,而我们常用的IC卡是ISO 14443协议的,所以并不好直接进行模拟。当然也不排除以后会更新方案完善IC模拟功能,现阶段这个方案对我来说是够用的啦。
Sorry, something went wrong.
目前市面上的门禁系统大部分只是读取卡片的uid,所以可以方便复制,如果碰到cpu加密或者hid的iclass卡,应该就没办法了
