Abstract
A radio frequency identification (RFID) capture system for identifying and recording information parameters associated with cargo items. A choke point portal defines a doorway through which passes a plurality of the cargo items in transit from a first location to a second location. The portal includes a radio frequency scanner and a plurality of antennas mounted at specified locations along said portal and in operative communication with said scanner for issuing a radio frequency signal scan across a three dimensional space preceding the portal doorway. A plurality of radio frequency sensitive labels are affixed to selected cargo items. A processor based operating system is in interfacing communication with the portal scanner. In response to each of the labels signaling a selected portal antenna and processor, the processor system captures the information from scanner and, upon comparing the information with an inventory manifest held in a computer readable medium, records the transport of the cargo item.
