I'm holding out; i don't want to install yet another app, i want to wave my watch at the thing and have gas come out without mobil knowing more about me.

Back in the 90's Mobil had a little thing you put on your keychain that did this. It was shaped like a plastic tube about the size of a match, but thicker.

I don't know what happened to it. My guess is that since most gas stations are small businesses, they didn't want to pay to upgrade all of their pumps.

I find myself using these systems more as well. Publix, Kroger, and Walmart all have respective apps where you can scan a QR code on the screen (for both non-self-checkout and self-checkout) and pay using a card on file. Although, I think I use them only because they've chosen to not support Apple Pay and other mobile payment providers.

I'd continue using the Walmart app to pay in their stores even if they did start supporting Apple Pay on their terminals.

That's because those sales show up as being in the "online shopping" category for my credit card despite actually taking place in store, and I've got a card with very good cash back rewards for online shopping.

I prefer St1 stations in Finland because I can pay with the St1 credit card inside the St1 app. Really, the biggest benefit of using the app is that I don't have to stand in front of the payment terminal during winter, but I can rather just stay in the warm car until the pump is initialised and then just quickly go fill up.

Shell and Exxon have the same.
