The most common credit card in Denmark is VISA, but most ATMs accept Mastercard and American Express as well.

In Copenhagen, most hotels, stores, cafes, and restaurants accept most major credit cards. It is a good idea always to ask beforehand, as some places might charge a fee when accepting foreign credit cards as payment.

Please note that PIN code and a picture ID might be required when using a credit card in Denmark. 

Most shops in Denmark accept cash, but there is an increase in cash-less shops where it is only possible to pay by credit card or mobile. You should also note that some kiosks and supermarkets do not accept cash after 8 pm.
