In most systems, vehicles using the system are equipped with an automated radio transponder device. When the vehicle passes a roadside toll reader device, a radio signal from the reader triggers the transponder, which transmits back an identifying number which registers the vehicle's use of the road, and an electronic payment system charges the ...

Gallegos said APD currently has five Grappler devices, which cost $6,000 each. He said it costs $600 to replace the net after each use, and officers have used the devices 30 times.
Transponder encryption keys are user programmable, using a simple over-the-air protocol. Once correctly programmed, transponders may be "locked" through a separate command, which prevents further changes to the internal key value. [4] Each transponder is factory provisioned with a 24-bit serial number and 8-bit manufacturer code.
