SunPass is an electronic toll collection system within the state of Florida, United States. It was created in 1999 by the Florida Department of Transportation's (FDOT's) Office of Toll Operations, operating now as a division of Florida's Turnpike Enterprise (FTE). The system utilizes windshield-mounted RFID transponders manufactured by TransCore and lane equipment designed by companies including TransCore, SAIC, and Raytheon.
Signs on Orchard Pond Parkway near Tallahassee indicate payment is only by SunPass or toll-by-plate.
Electronic toll collection
Electronic toll collection (ETC) is a wireless system to automatically collect the usage fee or toll charged to vehicles using toll roads, HOV lanes, toll bridges, and toll tunnels. It is a faster alternative which is replacing toll booths, where vehicles must stop and the driver manually pays the toll with cash or a card. 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 user the toll.
E-ZPass tollbooths, like this one on the Pennsylvania Turnpike in Bensalem Township, Pennsylvania, use transponders to bill motorists.
Many ETC systems use transponders like this one to electronically debit the accounts of registered cars without their stopping.
