Here between Montreal and Laval there is a bridge owned by a private company called A25. Cameras are installed that take a picture of your license plate as you cross the bridge. Connected to some database somewhere, they determine your plate number and mail you an invoice to pay for crossing the bridge.

For frequent users of the bridge like me, a transponder is installed on the windshield. (I think it uses RFID but I'm not sure). Transponder users get a 60% discount on use of the bridge and get charged to their credit card. (I get free use of the bridge with no cost whatsoever because my car is electric).
