북유럽 4개국을 방문할 때 현지 통화를 가져가지 않고 신용카드만 사용할 수 있나요 ?

일부 작은 식당은 외국의 신용카드를 수수하지 않습니다. various buses, intercity buses except, do not accept credit cards, nor cash, only recognize the bus card. Norway can use credit cards at 7-11 to buy one hour and 24-hour cards. In theory, you don't have to bring local cash, but for insurance, it's better to bring some. How much, you calculate it yourself. I changed 1000 Norwegian and Danish crowns. I didn't go to other countries.
