RFID testing and classification systems and methods
First Claim
1. A radio frequency identification (RFID) test system comprising:
- a transmission system for providing a radio frequency signal to a plurality of RFID devices;
a plurality of radio frequency detectors configured to detect a response to the radio frequency signal from the corresponding RFID devices; and
a circuit coupled to the radio frequency detectors and adapted to determine whether each of the plurality of RFID devices is operational based on whether the response was detected by the corresponding radio frequency detector, wherein the RFID device is deemed operational if the response was detected and without the circuit decoding all of the response.

Abstract
Systems and methods are disclosed herein to provide radio frequency identification (RFID) test techniques. For example, in accordance with an embodiment of the present invention, an RFID test system includes a transmission system for providing a radio frequency signal to a plurality of RFID devices and a plurality of radio frequency detectors configured to detect a response to the radio frequency signal from the corresponding RFID devices. A circuit is coupled to the radio frequency detectors and adapted to determine whether each of the plurality of RFID devices is operational based on whether the response was detected by the corresponding radio frequency detector. The RFID devices, for example, that fail the test may be provided with an identifying mark or disabled with a kill command.
