I also can't remember the last time I had to swipe a card where I am in the US. I also prefer using Apple Pay, and tbh, can't remember the last time I had to use my physical card.
It's still relatively common to have to swipe cards at gas stations in the US when you're buying gas. And a fair amount of the parking meters may still be on swipe (NYC meters outside of Manhattan come to mind). The places that haven't upgraded are ones with a lot of POS stations to upgrade.
Yep these two places are very common to be swipe only. I have to go a human teller at <massive and famous hospital> to pay for parking and the cc machine will still only read swipes.
