How do you do it, asks commenter low-tech cyclist. Well, here’s how London does it:
Cameras at entrances, exits and around the zone read your number plate. They check it against a database to work out whether you’ve paid already, are exempt, or have a 100 per cent discount. We keep checking the database until midnight the following charging day.
If we get a match, we automatically delete any images of your vehicle from the database.
If we don’t get a match, we check and validate all the images and send a Penalty Charge Notice to the registered keeper of the vehicle.
There are about ten different ways to pay, including online, by phone, and at physical locations. It’s basically like the District’s existing speed cameras, only everyone pays. So, not that tricky.
