问题描述

我从恩智浦半导体1型NFC标签......我试过很多Android应用重置或格式，从来没有工作过，它说保护或阻止。

推荐答案

类型1 NFC标签有一个简单而有效的保护机制。

Type1 NFC Tags have a simple but effective protection mechanism.

有标签上的一次性可编程锁定位。每次这个锁定位使得对只读（简化视图）标记8个字节的数据。

There are one time programmable lock bits on the tag. Each of this lock bits makes 8 bytes of data on the tag read only (simplified view).

一旦这些位被设置内存写保护，直到永远。想想锁定位为保险丝：一旦他们被烧断没有办法向联合国打击他们。也没有主键，将标签进入读/写状态左右。

Once these bits are set the memory is write protected for ever. Think of the lock bits as fuses: Once they are blown there is no way to un-blow them. There is also no master key to put the tag into read/write state or so.

长话短说：有什么是你可以在一类型NFC标签开裂。

Long story short: There is nothing you could crack on a Type1 NFC tag.
