There was a BBC News article on how Sweden is pushing very hard to go cashless. Many shops their now only accept card payments.
Indeed, I was in Stockholm recently and everyone took card, even the humble hot-dog vendor on the corner. Some shops the staff seemed almost offended if you tried to use cash. I took 1000kr (~£90) cash with me expecting to burn through it in the first couple of days, came back with about 700.
