I first mentioned the phone-enabled parking charge payments in this article several months ago. Recently, while visiting friends in northwest London, I came across an entire area where all of the parking meters have been converted into the pay-by-phone operation.
I suppose in this day and age everyone – and their grandmother – has a mobile phone on them. And if someone who needs to park on that street does not, I’m sure that getting a parking ticket will provide enough of an incentive to get a mobile, if only for parking convenience. Mobile operators benefit too, to say nothing of drivers with no spare change in their pockets.
