There does seem to be progress therefore of a sort on making life easier for Londoners to pay the Charge which is certainly to be welcomed. I am very surprised that you say these two technologies are not quite compatible. You have automatic number plate recognition which is already working. You have your Oyster card which is already working. I would have thought that it would be a fairly simple matter as soon as the camera picks up the number plate to identify the driver and dock it from his Oyster card. That seems to me to be a very good solution, make life a lot easier and reduce administration.
