Abstract
The present invention is directed to a method and apparatus for visually locating 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 the container, wherein each second RFID tag is coupled to a respective illumination source; addressing one of the first RFID tags; and activating the illumination source coupled to each second RFID tag that captured the ID of the addressed first RFID tag.
