Abstract
A radio frequency identification seal comprises an antenna including a main antenna portion and at least one break-away portion and an RFID tag coupled and tuned to the antenna. The RFID tag outputs a signature in response to a scanning signal when tuned to the antenna.
Claims25
A container comprising:
- a container body;
- and
- a seal on at least a portion of said container body, said seal including an antenna and a tag tuned to said antenna, said tag becoming detuned when said antenna is compromised during opening of said container.
A radio frequency identification seal comprising:
- an antenna including a main antenna portion and at least one break-away portion;
- and
- an RFID tag coupled and tuned to said antenna, said RFID tag outputting a signature in response to a scanning signal when tuned to said antenna.
A structural material comprising:
- at least one radio frequency identification (RFID) seal affixed to the structural material at a location prone to fatigue, the at least on RFID seal comprising:
- an antenna including a main antenna portion and at least one break-away portion;
- and
- an RFID tag coupled and tuned to said antenna, said RFID tag outputting a signature in response to a scanning signal when tuned to said antenna,
- wherein when the structural material undergoes fatigue adjacent said location, the at least one break-away portion separates from the main antenna portion thereby to detune the RFID seal.
2 more elements
A ribbon comprising:
- a substrate;
- and
- a plurality of radio frequency identification (RFID) seals on the substrate, different RFID seals detuning in response to differing tensile loads.
