It could be helpful for you to have a bank account in Konstanz during your stay at the University of Konstanz. Usually wages or scholarships are electronically transferred to a German bank account. We thus recommend opening a Girokonto (checking account). Once you open the account, you can use your EC card to get money from a cash machine and to pay for items in many shops.
A wide range of banks in Konstanz offer such accounts, which may vary in type, services provided and price.
