Question

使用我在旧钱包中找到的未使用的RFID卡（MIFARE Classic 1K），我决定将其克隆到空白卡上。

执行nfc-mfclassic w X u <Original Card file name> <Blank Card file name>后，我在新克隆的空白卡上执行了mfoc -O，结果是所有内容都被克隆为原始卡。但是我注意到，在将新克隆卡的转储与清空空白卡的转储进行比较时，我发现在使用nfc-mfclassic w X u命令进行克隆的过程中没有克隆扇区0的值。我知道制造商阻止空白卡，制造商块可以克隆，但为什么在这个例子中它没有这样做？

下面是清空空白卡克隆前的十六进制转储。

Answer 1

MIFARE Classic卡第0区的第一个区块是制造商区块。此块在普通卡硬件上是只读的，因此无法克隆，因为您无法将其写入另一张卡。

然而，存在特殊硬件（专用卡仿真器，如Proxmark，以及来自其他制造商的特殊MIFARE Classic标签，所谓的中国克隆卡），允许写入制造商块。您可以使用此类专用硬件来存储包含第一个块的真实卡片的克隆。

无法克隆整个RFID卡
