Here in Spain it is still relatively common to make a bank transfer and show the receipt. Especially for anything government related. Stand in queue, talk to person. You need to pay 12 euros. Go to bank, pay, get receipt. Go back and stand in the queue again.

We don't need to be giving our governments any more control over the way that we spend our own money. And we certainly don't want to give them the power to shut people out of the system.
