Solved! Go to Solution.
Hello @takuyaota
Each ICODE SLIX2 UID is signed with an NXP private key and the resulting 32-byte signature is stored in a hidden part of the ICODE SLIX2 memory during IC production. This signature can be retrieved using the READ_SIGNATURE command and can be verified in the NFC device by using the corresponding ECC public key provided by NXP. The signature can only be read, and the saved address is private and cannot be written, so there is no risk of tampering.
