Radio frequency identification (RFID) surveillance tag
First Claim
1. A radio frequency identification (RFID) surveillance tag for use with an associated packaging comprising:
- a tag body;
a back plate coupled to said tag body, said back plate including predefined mounting features for mounting to the associated packaging;
a battery power supply;
a plurality of sensors monitoring the associated packaging, said plurality of sensors including a seal sensor;
a respective control logic function coupled to said plurality of sensors including said seal sensor and said battery power supply;
said seal sensor including a force sensitive material providing a resistivity change responsive to change in a seal integrity change of the associated packaging; and
said respective control logic function coupled to said seal sensor responsive to said resistivity change, generating a seal integrity tag alarm; and
a sensor memory storing each said generated seal integrity tag alarm.

Abstract
An enhanced method and apparatus are provided for tracking and managing a plurality of packagings, particularly packagings containing radioactive and fissile materials. A radio frequency identification (RFID) surveillance tag is provided with an associated packaging. The RFID surveillance tag includes a tag body and a back plate including predefined mounting features for mounting the surveillance tag to the associated packaging. The RFID surveillance tag includes a battery power supply. The RFID surveillance tag includes a plurality of sensors monitoring the associated packaging including a seal sensor. The seal sensor includes a force sensitive material providing a resistivity change responsive to change in a seal integrity change of the associated packaging. The resistivity change causes a seal integrity tag alarm. A tag memory stores data responsive to tag alarms generated by each of the plurality of sensors monitoring the associated packaging.
