Abstract
A tamper indicating label is provided. The label may include RFID components and a tamper track coupled to the RFID components. The tamper track should be constructed from a destructible conducting path. Additionally, the tamper track can be formed such that it is damaged when the label is tampered. In one embodiment, adhesion characteristics of the tamper track are adapted to break apart the tamper track when the label is tampered, for example, by removal from an object. The RFID components may retain their RF capability and detect when the tamper track has been damaged to indicate that the label has been tampered. Alternatively, the RFID capability of the RFID components may be disabled when the tamper track is damaged, indicating tampering.
