When the recipient accesses a transaction where NorskID is chosen, they have the option to choose between BankID or BankID Mobile:
"Norwegian BankID" can be used as a signature on all documents and is a binding signing method. This signature form is more secure than an old-fashioned signature made with a pen on a piece of paper. This is because a stamp is electronically incorporated into the signed PDF, in which several pieces of information about the signatory are stored.
BankID Mobile is an alternative option for identifying and signing documents. Here you use your phone for 2-factor authentication. What you need to be aware of with BankID Mobile is that, as first assumed, it is not possible to sign multiple documents at once if the Sign multiple documents with one signing key feature is enabled.
