The ezpass system uses a ticketing system. That's not that same at the 407. Ezpass you have a ticket and its a prepaid account the machine reads.
407 is a completely differently technology. You enter in (there is no gate that lifts up, btw), and a camera is placed wayyyy high up to read your license plate. The billing system will recognize your licence plate, your address and send you a bill. You don't have to stop or slow down and feed a machine.
Everything is electronically done with sensors and camera. If you have a transponder, the sensors will pick it up and give you discount by waving you $3.30.
That's why it's called ETR. "Electronic" toll system because everything done with minimal effort. I have yet to see EZpass use camera/sensor technology and send the customer the bill.
