SunPass
SunPass is an electronic toll collection system in use by the State of Florida and was originally created by the Florida Department of Transportation's Florida's Turnpike.
The system uses Amtech active RFID windshield-mounted transponders manufactured by TransCore along with lane equipment designed by several companies including SAIC, TransCore, and Raytheon.
SunPass is fully interoperable with E-Pass (from the Central Florida Expressway Authority), O-Pass (operated by Osceola County; operations have been absorbed by E-Pass), LeeWay (from Lee County toll bridges) and Miami-Dade Expressway Authority (MDX) toll roads.
