One of the primary reasons to . Secure Tag Erasing. NFC interactor is the first app for Windows Phone that securely erases tags by overwriting the complete writable memory area. Instead of writing the minimum-sized 3 bytes message, NFC interactor will .
How can I determine if this write protection is permanent, and if not, remove it?

Its an extended command promt for the nfc implant. Is it possible with this to write directly to the CC E3 memory to “erase” the broken bits? You can simply overwrite (given that the tag is not read-only) any existing NDEF message by using the writeNdefMessage() method of the Ndef object. E.g. to "format" the tag to an empty NDEF message, you could do something like:
