> In most places in the USA / the rest of the world -- it's a 'swipe and go' sort of deal.

In most of EU you never swipe. I have swiped maybe 2x in my life and only because the chip did not work. (The swipe then did not work either...) You either use chip/pin or contactless and pin over 20eur

In most places the magstrip is disabled (both on the cards and in the readers) because it's insecure and there was a lot of low-effort cloning going around.

The hardware to clone magstripe cards is shockingly cheap and easy to get hold of.

I was tickled a few years ago when Samsung tried to roll out mobile payments in the US and had to include a kind of hardware magnetic stripe emulator in their phones, chip & pin is nowhere near ubiquitous yet.
