Digital Signature - MitID
MitID is your digital signature and is just as legally binding as your personal signature on a document.
You need your digital signature, as the Danish authorities are sending almost all mail to the citizens electronically, and to a great extent it requires that you use digital solutions when filling in forms to public authorities.
You also need your digital signature if you wish to use the electronic self-service options/netbank of the banks, just as a number of companies, i.a. insurance and pension companies give access to self-service solutions by means of your digital signature.

Denmark has recently replaced NemID with MitID.
You can use MitID almost immediately once the MitID app is downloaded on your smartphone or tablet.
As a foreigner or as a Dane with an eID from another EU/EEA country, you can use Danish digital self-services. Read more here.
You can read more in English about electronic mail on E-BOKS.
