Abstract
Systems and methods for location determination using radio frequency tags are disclosed. In one embodiment, a method may include (1) a back end server receiving, from a RF sensor in a network comprising a plurality of RF sensors, a unique identifier for a sensed tag and an identifier for the RF sensor; (2) the back end server retrieving a location of the RF sensor based on the sensor identification; (3) the back end server associating a sensed tag location with the location; (4) the back end server retrieving authorization information for the sensed tag based on the unique identifier; and (5) the back end server determining that the sensed tag is authorized to be in the location.
