As a Swede, I can't recall the last time I used cash in a normal commercial context - that is, not dealing directly with another private citizen - since I turned 18 and got my debit card 13 years ago. I can't recall the last time I used the magnetic strip either. It's all chip for me, and it's free of charge barring the 25 SEK (~2.5 EUR) per month the bank asks me for my complete account setup.
