As Norway goes almost cashless, you are surely to come across an ATM machine everywhere during the whole trip. Yes, you got it right, everywhere. Even in most rural areas of the country, there should be at least one point available, for instance, a petrol station, where you will be able to withdraw money.
Although the name of the currency for Norway, the Norwegian krone, is translated as "a crown", recently cash has been overthrown form the leading positions of payment. Of course, having some cash with you, just in case, is a wise idea but still, you’ll probably be glad to know that most places easily accept debit and credit cards.
