From what I can tell, most gas stations aren't set up for chip cards. I got gas last weekend at a Shell station in SF and was surprised to see the reader was chip-capable. Seems like it's still pretty rare. It's moderately insane that gas stations have been allowed to drag this out so much, considering that gas pump readers are a huge target for card skimmers.

(Then again, I guess a chip reader doesn't stop people from putting in a skimmer that just reads the card number as usual through the magstripe.)

The pump also had a pad for contactless payments, but I couldn't get it to work with either my phone or the NFC chip on my credit card. Maybe it only works with Shell's own card? Wasn't clear.

(And at the complete other end of the spectrum, I then went to top up my tire pressure, only to find that the air pump wanted quarters, and only quarters. Fortunately the attendant turned it on for me for free. I usually don't carry much cash around with me, and even more rarely have coins.)
