METHOD AND APPARATUS FOR READING SHORT DISTANCE EMISSION RFID TAGS TO LOCATE ITEMS IN A CONTAINER

摘要

The present invention is directed to a method and apparatus for reading short distance emission RFID tags to locate items in a container. A method in accordance with an embodiment of the present invention includes: initiating a reading sequence of a plurality of first RFID tags, wherein each first RFID tag is associated with a respective item located in the container, and wherein each first RFID tag emits an identification (ID); capturing the ID emitted by each first RFID tag using a plurality of second RFID tags located in a vicinity of the first RFID tag; interrogating the plurality of second RFID tags to obtain the captured IDs; and determining a physical location of an item in the container based on the captured IDs.
