> 10-15 years ago, you couldn't swipe your ATM/credit card at the grocery store.

I clearly remember doing so 15 years ago.

I clearly remember doing so 25 years ago in many countries.

I could be wrong on the exact dates, but I'm quite certain it wasn't widespread. I didn't see it until the early 2000's.

Regardless, you certainly didn't do it in 1986 (which is jbooth's timeline).

I'm almost certain yOu could in parts of Canada in 1986.

Indeed, even in 1976: http://financialsector.blogspot.com/2006/12/td-green-machine...

I'd include that under "ATM machine", more or less.

Quite often there would be only one or two "credit" lines for people using credit cards.
