2) Bank account
In Germany it is common to pay smaller sums in cash. Apart from cash, debit and credit cards are usually accepted. If you are staying in Germany for an extended period, are receiving a regular salary or fellowship and have to pay rent, it is a good idea to open a current account at a bank at the earliest opportunity. You can open a current account at any bank, the nearest ones are located at Zülpicher Straße, Dürener Straße and Luxemburger Straße.
