Multiple RFID devices may be tested by moving a sheet, roll, or web of the
devices in conjunction with a test apparatus having multiple RFID device
testers, so that the RFID devices to be tested are each spatially static
with regard to one of the RFID device testers for a period of time,
during which testing may be performed. The device testers may be arrayed
along the circumference of a circular test wheel or roller, or may be
arrayed along the perimeter of a flexible belt. The coupling between the
RFID devices and the RFID device testers may be capacitive. By utilizing
short-range capacitive coupling, difficulties caused by simultaneous
activation of multiple RFID devices may be reduced or avoided.
