Abstract: A radio frequency identification (“RFID”) method, computer-readable medium, apparatus, and system are provided. In one embodiment, the method acquires dimensions of an item. The dimensions and speed of the item are used to determine the item's location on a conveyor (i.e., to track the item on the conveyor). The location of the item is used to determine which switch RFID reader antenna in a plurality of RFID reader antennas is the most suitable RFID reader antenna to communicate with a transponder located on the item. In other embodiments, the apparatus, system, and computer-readable medium are also provided which perform similar features recited by the above method.

Abstract: A method for confirming information using multiple information gathering subsystems is provided. In one embodiment, the method attempts to gather primary information using a first information gathering subsystem. The method also attempts to gather secondary information using a second information gathering subsystem. Thereafter, the method compares the primary information when gathered by the first information gathering subsystem with the secondary information when gathered by the secondary information gathering subsystem. In various embodiments, information gathered from one information gathering subsystem can be used to derive information not retrieved (due to a failed gathering attempt) from the other information gathering subsystem. In still other embodiments, a third information gathering subsystem can be used to gather tertiary information. The tertiary information can be used when needed to confirm or derive primary or secondary information.

Abstract: A radio frequency identification (“RFID”) method, computer-readable medium, apparatus, and system are provided. In one embodiment, the method uses at least one light sensor to detect an item and to provide peripheral information of the item. Thereafter, the method determines the item's location, on a conveyor, from the peripheral information and a speed of the conveyor; and switches to an RFID reader antenna in a plurality of RFID reader antennas in accordance with the item location. In other embodiments, the apparatus, system, and computer-readable medium are also provided which perform similar features recited by the above method.
