an authentication server (101),
a controller (102) in communication with the authentication server and an NFC enabled device (300) configured to read and write data to a memory (202) of the NFC tag,
wherein the controller is configured to
request reading of a tag identification number (ID) from the memory of the NFC tag, when an NFC connection is established between the NFC enabled device and the NFC tag,
generate a tag record (103) of the NFC tag on the authentication server, associated with the tag ID,
generate a token (TS) corresponding to the NFC tag, wherein the token is generated by an algorithm (104) based on the tag ID,
request writing of the token to the memory of the of the NFC tag, when an NFC connection is established between the NFC enabled device and the NFC tag,
associate the token with the tag ID in the tag record of the NFC tag,
wherein, upon a user subsequently validating the asset, the controller is configured to request reading the token from the memory, such as by the NFC enabled device or a user device (301) configured for NFC read-only communication, and verify the token against the tag record for the tag ID comprising comparing said token with the associated token stored in said tag record on the authentication server.
