Abstract
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.
