Abstract

An approach is provided in which an RFID reader receives a response signal from an RFID tag affixed to an object. The RFID reader determines a tag charging time of the RFID tag based upon a first point in time that the RFID reader sent a request signal to the RFID tag and a second point in time that the response signal was received by the RFID reader. In turn, the RFID reader identifies a location of the object based on the tag charging time and generates a notification that includes the location of the object.
