  • a choke point portal defining a doorway through which passes a plurality of the cargo items in transit from a first location to a second location, said portal including at least one radio frequency scanner and at least one antenna in operative communication with said scanner for issuing a radio frequency signal;

    a plurality of radio frequency sensitive labels, each of said labels being affixed to a selected one of the cargo items; and

    a processor based operating system in interfacing communication with said portal scanner and, in response to each of said labels emitting a signal detectable by said antennas as the cargo items are transported to the second location, a processor in operative communication with said antennas capturing and comparing information derived from said labels with an inventory manifest held in a computer readable medium and for authorizing shipping of the cargo items upon reading a correct number of labels.
