I think they quit using them in the 80's.

I think most stores had them on a shelf well into the 90s, and probably until at least 2000-2005 if not later. If there was an issue, power outage or something, they would do the swipe thing, and then manually key the charges into the POS machines when the power came back, but had the old carbon style receipt in case someone tried to complain.
