Abstract
Embodiments of the invention provide a method of authenticating an item by affixing an RFID chip to the item. In one embodiment, an authentication method comprises providing an RFID chip having a unique ID readable by a device; applying the chip to an item via an adhesive; associating the ID of the chip with the item at a first point in time; and at a second point in time later than the first point in time, authenticating the item by reading the ID of the chip applied to the item and comparing with the ID associated with the item at the first point in time. The RFID chip cannot be easily removed and preferably cannot be removed without visible evidence of tampering, more preferably without destroying the RFID chip so that the ID of the RFID chip cannot be read.
