How to crack Asymmetrische cryptografie on a nfc tag?

have an nfc tag with I think Asymmetric cryptography. because when I scan this with the nfc tools I get 4 things, [tag type, technologies available, serial number, DSFID] and do not know what that means, but when I read another tag it had 20 times more options.

The question now is this Asymmetric cryptography and how can I find the public key and if I have it, how do I crack it?
