With gas stations, there is so much more to it than just replacing a card reader in the kiosk, or even just replacing the kiosk itself. You may have to even tear out all of the old networking equipment. https://news.ycombinator.com/item?id=28207062

Thanks, but the post you linked is making me irrationally angry. Why does a gas pump card reader need full internet connectivity?! It's outrageous! Just use the two wires to talk to a head unit in the building! Then it brings up the gas pump advertising screens which are already a sore point for me (two conveniently located stations have these, so I can't go there anymore because I find the accompanying audio intolerable).

The whole situation smells like it involves a lot of vendor lock-in, too (which I always hate to see).

EMV is a very very chatty protocol, basically.

Thank you for this. How much of an impact is this having 1+ years on? I'm sure it's still substantial but wanted to ask if you had any current data.
