Sweden is a member of the European Union (EU) since 1995, but not a member of the so called Euro-Zone. That is why the local currency is not the Euro, but the Swedish Crown (Svensk krona).
One Swedish Crown is subdivided into 100 Öre. Banknotes have the following values 20, 50, 100, 200, 500 and 1000 Crowns.
Cash money is available from cash points (ATMs) or exchange offices. However, credit cards are widely accepted and in use, but the pin code is almost always required.
