Yep, I know it's commonplace outside of America. The main difference, at least from all the times I've hit a drive-thru in Canada, is the PIN pads used outside of America are way smaller.
ROW typically has something like an iCT250 on a long cord they hand you. In my experience at Canada, they hand it to you and then from inside your car you can do your transaction.

Meanwhile, here in America, they have a big-ass MX860 on a pole that they hold out the window, while you lean out to tap, praying you can reach the NFC pad... or that you don't drop (and crack) your iPhone.
