Why is it not possible to embed the NFC tag in a destructible medium? Like those annoying stickers that you cannot peel without ripping?
If you use that, then the only way to move the NFC tag to another item would be to cut it out of the original item (including the original adhesive). But this attack also works against the technique in the article.
Regarding the orientation, I understand that it is nondeterministic in the original, but what prevents an attacker from copying it deterministically? Is it just that technology is not good enough to manipulate such small pieces of metal? How long will this limitation persist?
