Systems, tags 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 positioning (e.g., pivotably moving) a disabling member having a metallic portion to 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 member is at the operative position. The RFID circuitry is arranged to be automatically enabled upon removal of the disabling member from the operative position (e.g., pivoting the disabling member back to an inoperative position).
