Currency
In 2002 with the introduction of the Euro (€) as official currency of the European Union, Germany had to change its official currency, until then The Deutschmark (DM), for the Euro. Currently the DM is not accepted in Germany.
The euro and foreign currency and other forms of payment can be brought into and taken out of Germany without restriction. Travellers from the twelve member states of the European Monetary Union (Austria, Belgium, Germany, Finland, France, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal and Spain) can pay in euros by bank transfer or cheque. It is also possible to change money or cash travellers' cheques at any bank for a fee.
The best way to avoid paying expensive exchange fees is to withdraw cash directly from an ATM (look for a Bankautomat or Geldautomat). Before you go, ask your home bank if it charges a fee for using an ATM abroad.
