ABSTRACT:
Methods and systems of determining physical characteristics associated with objects tagged with Radio Frequency Identification (RFID) tags. At least some of the illustrative embodiments are methods comprising making a first reading of a RFID tag coupled to an object (an electromagnetic signal received from the RFID tag having a first received signal strength indication (RSSI)), making a second reading of the RFID tag (an electromagnetic signal received from the RFID tag having a second RSSI), and a determining whether the object is moving using (at least in part) the first and second RSSI. Other illustrative embodiments, may determine (in addition to or in place of determining movement) orientation of the object based, at least in part, on the electromagnetic signals.
