Thieves using stolen windshield toll transponders have charged about $4,000 worth of food at McDonald's, where the devices have been accepted as debit cards since April 2000, according to a Transportation Corridor Agencies spokeswoman. The transponders, which operate with a radio signal that credits tolls--and now cheeseburgers--to motorists' accounts, allows users to skip toll plazas. The agency receives 20 cents each time a McDonald's purchase is made with a FasTrak. Spokeswoman Clare Climaco said people should treat a transponder like a credit or debit card. "They should take it out of their windshield and put it in a glove compartment or purse when they're not using it," she said. http://latimes.com/news/local/state/la-000060199jul23.story?coll=la%2Dnews%2...
