Below we have listed the different signing methods.

With a screen signature, the signer signs the document by drawing their own signature, possibly with a touchscreen on a phone or with a touchscreen, mousepad, or mouse from a computer.

It is also possible to upload an image for this type, but the image must be in one of the following formats:

A signer signs the document with a single click on an "OK" button. This can be used in cases where it needs to be quick.

An OK signature is just as valid and binding as a touch signature.

When the OK button is used, the participant's name is added as a visible stamp on the finalized document.

"Approve" is the only signature method that is not shown on the final documents. This is used in cases where the flow includes, for example, a buyer, a seller, and an intermediary. Approvers' actions are recorded in the transaction history, even though their names or signatures do not appear on the finalized document.

This could be in real estate transactions, where the agent should not sign but only forward a purchase offer.

Samleikin is the Faroe Islands' national eID and can be used for both digital identification and digital signatures.

If your organization collects signatures from people in the Faroe Islands, Samleikin can be enabled as a signing method in Addo Sign. It can be used either as a standalone signing method or as part of Nordic eID.

When signing, the signer verifies their identity using the Samleikin app or a USB security key and completes the signature digitally.

A digital signature created with Samleikin has the same legal validity as a handwritten signature under Faroese law.

In addition to Denmark, Norway, Sweden, and Finland, the remaining countries in the EU are obligated to accept electronic signatures and identification from all EU member countries from September 2018 according to the eIDAS regulation.

Each member country must therefore also establish, maintain, and publish a list of trusted service providers along with information about the trusted service they offer.

Addo continuously expands regarding new signature and identification possibilities.
