Systems and methods are disclosed herein to provide variable test
techniques for RFID devices. For example, in accordance with an
embodiment of the present invention, a radio frequency identification
(RFID) test system includes an RFID reader adapted to provide an RF
signal to an RFID device, wherein a signal level of the RF signal changes
as the RFID device moves through a test region. The performance level of
the RFID device is determined based upon the number of times the RFID
device responds to the RF signal.
