Abstract
Methods and systems for locating objects are disclosed. An electronic tag is attached to an object before storing the object. The electronic tag is identifiable by a unique response code. The response code and information pertaining to the object are recorded and the object may then be stored. To locate the object, the response code is entered into an interrogator. The interrogator sends a signal that causes the tag to emit a sound. The system thus allows for random storage of objects and is also useful for locating misplaced objects.
