The invention disclosed provides an apparatus and method to monitor and track the security of bulk cargo from a dispatch point to a receipt point. The apparatus includes a plurality of RFID antennas at a dispatch location and at a receipt location, networked software modules in communication with the RFID antennas, and disposable RFID tags used as security seals affixed to a carrier at multiple locations. The software modules include a Cargo Registration Module, a Dispatch Scanning Module, and a Receipt Scanning Module. The apparatus and method reduce cargo inspection time and labor at the points of departure and receipt. The automation of the dispatch and receipt process eliminates the human element thereby increasing the efficiency of the process. An additional embodiment includes a "single-use" disposable RFID tagged seal adapted to be attached to a transport portal unable to be removed without damaging an RFID transmitter contained within.
