Zusammenfassung: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.
