ID-card and Digi-ID are the easiest, most convenient and most secure methods of using internet banking and other e-services in Estonia.
Digital identity card or Digi-ID is an ID-card like a smart card, that you can use for authentication of the holder and giving digital signatures in an electronic environment. Also encryption functionality is supported.
You can apply for Digi-ID if you are:
a citizen of the Republic of Estonia who has a valid ID-card, or if you apply for Digi-ID along with the ID-card
an alien with a valid residence card/ID-card, or if you apply for Digi-ID along with the e-residency card
You need the following to use the ID-card and Digi-ID electronic services:
