I just moved from Sweden. I used cash frequently, but not in large quantities. Cashlessness is helpful in some cases, but a burden in others.

It is true you can get by without cash in Sweden but you cannot get by without a card, reasonably. But many of the corner markets have minimum payments by card, and so often having smallish money in cash is a very good thing. Additionally the farmer markets in the town squares are still mostly cash-based.

So I never found cashlessness to work entirely while I was there, whether I was in Malmo, Helsingborg, or Landskrona. Maybe in Stockholm it is different, and maybe it is different if you rarely buy at the farmer markets....

Germany, where I now live is the opposite. You can get by without a card, but you cannot get by without cash....
