How does the NTAG originality signature work?

According to the documentation the originality signature is the UID signed with the NXP private key.

 

Both the UID and the signature are readable.

 

If someone fakes a tag and makes the UID and the signature identical to the original tag, how would I be able to detect the forgery?
