Currency
Although Denmark is a part of the European Union, it still retains its own currency, "Den Danske Krone".
Danish cash
A bank service is available in the baggage claim area and to the left when you exit customs in Terminal 3. There are also cash withdrawal machines (ATMS) there, and on the street (outside of banks) in many places in Downtown Copenhagen; look for a sign that says KONTANT (cash). Furthermore, there are other cash exchange services downtown. Banks close at 4 PM. Here are the latest exchange rates >>
