BBC News : Congestion charges face legal challenge

[Peter Tomlinson]

Of course it will be possible to make the payment. Proof that the vehicle
was there could only come if the database is prepared to store the detection
of the vehicle AND release that information.

I think there is a group provision under which a fleet of vehicles can buy
so many day permits, and list all the regn numbers. Then, every time one of
the vehicles is detected entering, the credit is decremented until it has
all gone. To audit that, the database has to store the regn number and date
detected.
