Abstract:
A system for, and method of, locating a particular item from among a plurality of items identifiable by radio frequency identification (RFID) tags associated with the items, includes an interrogator for radio frequency (RF) signaling the tags to detect unique identifiers associated with the tags in a field of view of the interrogator; and an optical signaler for optically signaling one of the tags in the field of view to designate the particular item to be located.
