We have it in the UK for some petrol stations. My local one before they had pay at the pump allowed you to go to the cashier put your card in the machine and enter your pin tell them how much fuel you wanted and then the pump would only deal out up to that amount.
You only got charged for the amount of fuel taken, so it didn't matter if you said you needed 30 pounds worth and only took 26 pounds worth.
I guess it was similar to pay at pump now, where you enter your card and pin to pre-approve up to 99 pounds, fill up and then only get charged for the amount you took.
