Anti-cloning nfc tags

[Luca1]

I wonder if there are any nfc tags that prevent any kind of cloning. I am worried that I use nfc tags that are easily clonable.

Hi @Luca1 :

Some tags have originality check feature.  For example NTAG424, it supports two types of originality check, one is based on an LRP authentication with AES originality keys and another one with a static signatures verification with an ECC public key. You can use them for checks.
