Radio frequency identification for advanced security screening and sortation of baggage

摘要

An RFID conveyor system comprises one or more wedges designed to allow an RFID scanner to detect and uniquely identify RFID-tagged baggage as they are conveyed through an antenna array. The RFID conveyor system can also be designed to prevent the reading of previous or subsequent bags by using antennas with highly focused RF read fields in conjunction with RF energy absorbing materials, such as RF curtains, designed to eliminate the identification of any baggage located outside of the “read” area.
