ABSTRACT:
Embodiments of the present invention disclose an efficient and inexpensive method for detecting tampered products utilizing current off the shelf components. Features of some embodiments provide for a RFID labeling system that uses multiple RFID components attached to a single product unit being embedded in the product's label and one or more tamper labels. Such RFID labels usually comprise an adhesive label containing an RFID component, a destructible conducting path that acts as an antenna and a unique encryption. The RFID labels transmit the encryption when irradiated by an RF scanner. A complete inventory of multiple associated encryptions reported during an RFID scan of a product package provide positive indication that product has not been tampered with. A missing encryption indicates a faulty product seal or an event of tampering.
