I'm in Oregon where we (mostly) legally can't pump our own gas. There may be pumps that are like vending machines: they take cards or cash.
There are exceptions, like if you're in the rural areas (counties under 40,000 residents). They also changed it for a while during the early part of COVID.
I notice that the pumps still run the commercials on the pumps here. Probably cheaper to just build one model of pump even though Oregon and New Jersey but it would drive me crazy if I was pumping gas for a living.
I realize that there are gas stations where you can't pay at the pump, but that's not the claim I was responding to in the PC.
Regardless, if you are using your credit card to pay for your gas (which I am certain you can do in Oregon gas stations), the gas station is utilizing internet in order to give you gas.
