MitID is primarily an app
If you are in the habit of using the NemID app, you will not experience a significant difference. Once you have created your MitID, you can choose the new MitID app and use it in much the same way you are use to from the NemID app. The code card is discontinued because it is too easy to copy and abuse. If you cannot use the MitID app, you have alternatives. See alternatives here.
