I'm traveling from Oslo via Norway in a Nutshell to Bergen in early September. I researched on credit card use in Norway, and it looks like CCs are very widely accepted, just like where I live ( New York City ). One post on TripAdvisor from 2014 suggested that we can go almost cashless in Norway. I will travel with my VISA card with a chip, and am hoping except a few purchases, like the Gudvangen-Voss bus and the airport bus in Bergen, most transactions are possible with my credit card.
However, I read a website that says that in Norway almost anything can be purchased with CCs, but supermarkets don't accept them. Is it true? I will probably heavily rely on supermarkets.
Other expenses I'm hoping to use my CC to pay for are:
1. Attractions. For instance: National Gallery, Fram Museum and Norwegian Folk Museum in Oslo / Edvard Grieg's home in Troldhaugen / Bryggens Museum and the funicular ride in Bergen.
2. Occasional use of public transportation in both Oslo and Bergen: buses, trams, ferries, subways....
I need to decide how much cash I should make before departure, at least to cover the initial cash payments. Can someone give me updated info regarding what is and what is not possible to paid for with CCs?
