Bank opening hours are frustratingly short by European standards. They are usually open between 9am and 4pm from Monday to Friday, with a 'late' opening until 6pm on Thursday nights. Banks do not open on Saturdays.
All expatriates with a residence permit are able to open a bank account. When you open your bank account, you will be asked for your residence visa, a copy of your passport and a letter from your employer, confirming the amount that will be paid into your account on a regular basis. You may also be requested to provide your tenancy agreement as proof of your address.
The majority of everyday purchases are made using cash or Dankort, the Danish card payment system. It is very useful to have a Danish bank account in order to have a Dankort card, as some smaller retailers and many supermarkets are not able to process payments made using an international VISA or Mastercard. It is also common for additional charges to be levied on payments made by credit card. Personal cheques are not frequently.
ATMs are available outside banks and in major supermarkets and shopping centres and they often offer interfaces in all of the major European languages. You can use the ATMs of your own bank for free, but a charge may be made if you withdraw money from another bank's machine. Visa and Mastercard are widely accepted in hotels and restaurants throughout Denmark, and can be used in ATMs to make cash withdrawals.
