Abstract
Systems and methods for identifying an object being extracted from or moved among a plurality of objects in a designated area, the plurality of objects equipped with transponders that emit a reply signal encoding an identifier. A set of antennas proximately located to the designated area are controlled to emit interrogation signals that cause the transponders to emit the reply signal in response. Sets of information are obtained regarding the reply signals received by the set of antennas, the reply signals including an indication of a signal characteristic and an identifier particular to the type of the object. The sets of information are analyzed to identify an identifier of the object being extracted based on fluctuations in the signal characteristic relative to the plurality of objects. One or more operations may be performed involving the object based on identification of the identifier.
