RFID testing and classification systems and methods

A radio frequency identification (RFID) device test system comprising:

• means for providing a signal to at least one RFID device;
• means for detecting if the at least one RFID device responds based on a portion of any reply provided by the at least one RFID device to the signal;
• and
• means for determining if the at least one RFID device is operational based on whether the at least one RFID device responds, wherein the at least one RFID device is deemed operational if the detecting means detects the portion of any rely without decoding all of the reply.

A radio frequency identification (RFID) device test system comprising:

• means for programming at least one RFID device to a first value;
• means for testing the at least one RFID device, wherein the testing means passes the at least one RFID device if the at least one RFID device begins to reply to a signal provided by the testing means;
• and
• means for providing a kill command to the at least one RFID device to disable the at least one RFID device that fail to store the first value.

A method of performing radio frequency identification (RFID) device testing, the method comprising:

• providing a signal to at least one RFID device;
• detecting if the at least one RFID device begins to respond to the signal;
• and
• determining if the at least one RFID device is operational based upon whether the at least one RFID device begins to respond to the signal, wherein the at least one RFID device is deemed operational if the at least one RFID device begins to respond to the signal during an expected time frame.

A method of performing radio frequency identification (RFID) device testing, the method comprising:

• programming a plurality of RFID devices with a first value;
• providing a signal to the plurality of RFID devices;
• determining if each one of the plurality of RFID devices is operational based upon whether the RFID device begins to reply to the signal;
• and
• providing a kill command to the plurality of RFID devices, wherein the RFID devices of the plurality of RFID devices, which fail to store the first value, will be disabled.

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, wherein each of the plurality of radio frequency detectors further comprises a voltage comparator;
• 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.
