Bank account, NemID and Digital mail
When you live in Denmark, you must have a bank account, which is also used as a NemKonto. A NemKonto is used by the authorities to pay benefits and the like. This can include reimbursement of overpaid tax or payment of a student grant.
When you open a bank account in Denmark, you can also use the bank's online banking system. To use online banking, you must use a NemID, which the bank issues to you. NemID is a digital signature and login solution used for self-service on the Internet.
In Denmark, residents over age 15 receive their mail from the authorities digitally in their digital mailbox. It is important to check your digital mailbox regularly.
