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. History SunPass was introduced on April 24, 1999, and by October 1 of the same year, more than 100,000 SunPass transponders had been sold. In early 2009, all Easy Pay customers automatically became SunPass Plus customers if they opt-in and have the privilege of using their transponders to pay for airport parking at Tampa, Orlando, Palm Beach, Fort Lauderdale and Miami airports. Customers can opt out of the SunPass Plus program. Functionality The Mini was introduced on July 1, 2008, and became available at retail locations. The Mini is a RFID passive transponder, about the size of a credit card, and requires no batteries. The transponder must be mounted on the glass windshield of the vehicle to work properly and, once applied, cannot be removed from a windshield without destroying the pass. The SunPass Mini sticker will not work on motorcycle windshields as they are not made of glass. SunPass Portable (or SunPass Pro) transponders can be transferred between vehicles. The Sunpass Pro portable transporter offers E-ZPass interoperability, unlike the Mini. Customers must establish an opening account of at least $10 to fund their tolls. Unused toll fees are only refunded if the user closes the account or takes advantage of a money-back guarantee. Technology SunPass-only toll lanes on most toll roads in Florida allow a vehicle to proceed through the tollbooth at speeds of up to as a safety precaution. The Turnpike utilizes all-electronic tolling (AET) and toll by plate which handles highway speeds. The mainline toll barriers have dedicated lanes capable of full-speed automatic toll collection at up to . Florida's Turnpike Enterprise converted the Homestead Extension of Florida's Turnpike, the Sawgrass Expressway, and the Veterans Expressway to open road tolling, utilizing the SunPass transponders, in September 2010, February 2011, April 2014, and June 2014 respectively, ceasing cash collection. This allows free-flowing movement on both toll roads, moving through toll gantries at the former toll plazas. Motorists without a SunPass are billed through toll by plate. Toll-by-Plate uses cameras and sends a bill to the registered owner of
