Abstract
A mobile radio frequency identification (RFID) system is described that includes a wheeled cart, a RFID reader mounted to the wheeled cart, a computer mounted to the wheeled cart and communicatively coupled to the RFID reader, and a directional antenna capable of being communicatively coupled to the RFID reader and movably mounted to the wheeled cart. The system also includes at least one omni-directional antenna mounted to the wheeled cart and capable of being communicatively coupled to the RFID reader. The computer is configured to process data received from the RFID tags and further configured to allow a user to selectively couple one or both of the at least one omni-directional antenna and the directional antenna to the RFID reader.
