我一直在绞尽脑汁，试图将多个Mifare Classic电梯卡复制到一个Ndef格式的Mifare UltraLight标签上。
问题是什么应该是类型(或RTD_类型)和NdefRecord的有效载荷?
此外，电梯读卡器记录这些记录的方式是否与记录普通卡的方式相同?
这是我从电梯卡上读到的，它不是Ndef格式的:

前4个字节是id，我不知道如何解释其余部分或如何将其包装成NdefRecord。这可能吗?TIA
标签不包含Ndef数据，卡是NdefFormatable，这意味着它能够存储Ndef数据，但它目前还没有被格式化为能够存储Ndef数据。
标签techList必须包含android.nfc.tech.Ndef，以便它当前存储Ndef数据。
因此，您试图做的事情是不符合逻辑的，并且您没有显示的是Mifare Classic卡上所有其他受密码保护的数据，这些数据是电梯系统实际使用的Mifare Classic卡。
既然你不能改变电梯硬件，这就更不可能了。
这就像两个人，一个用法语谈论烤蛋糕，另一个用中文谈论天气，当他们都发出声音时，他们无法理解对方，你也无法改变其中一个来配合另一个。
