Abstract: A method and system for testing a plurality of RFID devices disposed on a common carrier. In one embodiment, the RFID devices are evenly spaced along the length of the carrier, and the system comprises a short-range tester, a long-range tester and a computer, the short-range tester being coupled to the computer and having a short-range testing position, the long-range tester being coupled to the computer and having a long-range testing position, the long-range testing position being spaced downstream from the short-range testing position by a known number of device positions. In use, an RFID device of interest is first positioned at the short-range testing position, and the short-range tester reads a unique identifier for that RFID device and communicates the identifier to the computer. The carrier is then advanced so that subsequent RFID devices are read by the short-range tester.
