About Digital Signatures:

The TruST25 digital signature ensures the authenticity of ST25TV512 and ST25TV02K NFC chips. Successful verification of the signature means the chip is issued by STMicroelectronics and not a malicious issuer. For product authentication, checking the digital signature is one step in the “cascade of trust.” It prevents the use of counterfeit non-ST issued chips.

About UID

All NFC chips have a permanent, non-changeable unique ID (UID) that is written by the silicon manufacturer. For product authentication, a tag’s chip UID is compared to a list of allowed UIDs as a step in the “cascade of trust”. If the UID does not exist on the list, then the product is a counterfeit. The ST25TV512 and ST25TV02K chips have 8 byte UIDs.
