I've heard that Denmark, Norway and Iceland are mainly cashless which means people with smaller currencies like the AUD get bad conversion rates whenever they buy anything.
I have cash euros and USD from previous holidays which I would like to convert into kroner, but now I'm wondering if people will take cash in these countries. In fact, I'd much prefer to use these currencies than a card.
Is it worth getting euros and USD on a card, whereby we'll be hit with 2 conversion fees if buying in Australian dollars or just using our usual debit card and copping the cost of every transaction? I've never visited cashless countries. I find the process daunting.
Can anyone recommend Wise to use for kroner in these countries?
