There are still prompts on the terminal like “credit or debit” or “please enter your PIN” or “type your phone number for reward card points” or “push X if you want orphans to starve”. (Safeway has the last one commonly.)
The US is very far behind when it comes to payments. It's still quite common for someone to take your card and swipe it and want a signature.
Every time I go down there from Canada I get confused and feel like I've gone back in time 8 years.
When my dad comes from Canada to the US, he still has to touch it because he has to enter a PIN. But at most stores, when I use the chip from my US card, I don't have to touch the terminal at all.
