Thanks for reply.
Can you suggest an irreversible way?
We have studied a lot, but didn't find a way to prevent to take out the chip (NTAG 213, NTAG 213TT) from the tag.
NTAG 213TT or NTAG 413 DNA will lose the function of "Brand Protection " due to take out the chip from tag is easy.
You said: "An unpowered device cannot detect changes on an interface pin. This is physically not possible."
Because the Physical properties of the passive tag, the hacker can destroy the tamper wire or antenna and re-wired it, before any reader or cellphone reading the tag, the hacker can then attach the modified tag to fake product and sell it, our background server will treat this tag as genuine tag from us.
Could you give us some suggestion to avoid this situation?
Thank you very much.
