Do you have any companies you would recommend I contact regarding toll-collection systems? We would like to avoid tags not being read and drivers not being charged.
Most toll-collection systems use active RFID transponders. Since these broadcast a signal, there is very little chance a tag will not be read and that a driver not charged.
The leading manufacturers of active RFID toll-collection systems in the United States are Mark IV Industries and TransCore. There are others around the world, including Atlantia (in Italy), Computer Recognition Systems (the United Kingdom), Electronic Toll Collection (South Africa), G.E.A. (France), International Road Dynamics (Canada), JAI (founded in Denmark, with offices worldwide), Kapsch Trafficcom (Austria), Omron (Japan), Q-Free ASA (Norway), SAIC (headquartered in the United States, with offices worldwide), Siemens Electronic Tolling (Austria) and Toll Collect (Germany).
In recent years, some toll-collection operators have opted to use passive UHF RFID systems. These have the benefit of being less expensive than active tags and have no battery, so they do not need to be replaced (see RFID Puts Salt Lake City Drivers in the Fast Lane, for example).
