RFID TAG DISABLING SYSTEMS AND METHODS OF USE
First Claim
1. A system for enabling and disabling an RFID transponder located on a vehicle so that said transponder can be selectively disabled and enabled, said transponder comprising an antenna and RFID circuitry, said system comprising said antenna, said RFID circuitry and a disabling device, said antenna being fixedly secured to the vehicle, said disabling device comprising a member having a metallic portion arranged to be releasably secured to the vehicle at an operative position with respect to said antenna, whereupon said metallic portion of said disabling device is coupled to said antenna in such a manner as to disable said RFID circuitry so long as said disabling device is at said operative position, said RFID circuitry being arranged to be automatically enabled upon removal of said disabling device from said operative position.

Abstract
Systems and methods for disabling transponders used in electronic toll collection or other RFID systems, wherein the transponders include an antenna and RFID circuitry. The transponders can be selectively disabled by releasably securing a disabling device having a metallic portion at an operative position over the antenna of the RFID system, whereupon the metallic portion is coupled to the antenna in such a manner as to disable the RFID circuitry so long as the disabling device is at the operative position. The RFID circuitry is arranged to be automatically enabled upon removal of the disabling device from the operative position.

19. A method of selectively disabling a RFID transponder located on a vehicle and which is used in an electronic toll system or some other electronic system wherein a vehicle with an RFID transponder is to be interrogated by a reader to determine the vehicle'"'"'s presence at a certain location, the transponder being arranged to provide a first electrical signal when queried by a transmitter forming a portion of the electronic system and comprising an antenna and RFID circuitry, the antenna being fixedly secured to the vehicle, said method comprising:
-
providing the user of the system with a disabling device, said disabling device comprising a member having a metallic portion, releasably securing said disabling device to the vehicle at an operative position with respect to the antenna when it is desired that the transponder be disabled, whereupon said metallic portion of said device is coupled to the antenna in such a manner as to disable the RFID circuitry from producing said first electronic signal so long as said disabling device is at the operative position, the RFID circuitry being arranged to be automatically enabled upon removal of said disabling device from the operative position. - View Dependent Claims (15, 16, 17, 18, 20, 21, 22, 23, 24, 25)

26. A method of testing plural RFID transponders located on a vehicle, each of the transponders being arranged for use in an electronic toll system or some other electronic system wherein a vehicle with the RFID transponder is to be interrogated by a reader to determine the vehicle'"'"'s presence at a certain location, each of said transponders being arranged to provide a respective first electrical signal when queried by a transmitter forming a portion of the electronic system, each of said transponders including an antenna and RFID circuitry, the antenna of each transponder being fixedly secured to the vehicle, said method comprising:
-
providing at least one disabling device comprising a member having a metallic portion; releasably securing the at least one disabling device to the vehicle at an operative position with respect to the antenna of the particular transponder(s) to be disabled when it is desired to disable the transponder(s), whereupon said metallic portion of said at least one disabling device is coupled to the associated antenna in such a manner as to disable the associated RFID circuitry from producing said first electronic signal so long as the disabling device is at the operative position, said RFID circuitry of each transponder being arranged to be automatically enabled upon removal of the disabling device from the operative position with respect thereto.
