Gas stations are already this way. I've pumped gas at unattended or closed stations. The credit card machine works the same either way.


It’s pretty hard to steal gas from a gas station though. They take the money first and you can’t really take extra gas since it’s all measured.


That's not how it works in a lot of places. I almost always need to fill it up then go inside to pay.


Way back when, Safeway’s 10c off per gallon rewards would just continue stacking up. I saved up until my discount was more than the price of gas, and got myself a free tank.

I’ve always wondered how much it would have let me pump. The limits I’ve seen on pumping have always been on the dollar amount, presumably because they verify they can charge that amount before you start pumping.
