for electronic signing

It is necessary that the signature can be attributed to the person signing. Therefore, Skribble requires the identification of the signers.
The procedures differ depending on the type of contract.

Contracts without written form

The simple electronic signature (SES) or the advanced electronic signature (AES) are typically used for contracts without formal requirements. The identification requirements for SES and AES are low to medium.

Identification methods for contracts without written form:

Confirmed e-mail address

In case of the simple electronic signature (SES), signers are identified by their e-mail address. Anyone who has a Skribble account or is invited to sign by e-mail can sign with SES without any further measures.

Companies that record the identity of their employees by default can activate AES via the company e-mail address (AES for Business). Anyone with a corresponding e-mail address can sign with AES immediately.

Mobile number

Anyone with a mobile number can sign directly with the advanced electronic signature (AES). All signers have to do is provide their mobile number in their Skribble account to unlock signing.

Contracts requiring the written form

For contracts requiring the written form, the qualified electronic signature (QES) is typically used. The identification requirements for the QES are high, the identification must be done face-to-face or online via video or online banking.

Identification methods for the qualified electronic signature (QES):

Inhouse identification
A woman and a man are standing in front of a large software window and the man is holding a big hatch with an identity card inside.

Selected employees of your company go through a one-time training. Afterwards they can independently identify signers face-to-face on site. Suitable for companies with a large number of QES signers.

Online identification
A man is sitting in front of a laptop, above him is a sotware window, where a woman stands out with a big magnifying glass and checks an identity card.

The signers can enable the QES by getting identified via live video call or face-to-face at one of our partners' locations in Switzerland. In the EU, also identification via online banking or app is possible. Suitable for individuals and companies with a small number of QES signers.

Electronic identity (eID)

Anyone with an eID can log in directly to Skribble and sign immediately without further identification. Depending on the level of assurance of the respective eID, the advanced (AES) and/or qualified electronic signature (QES) is activated straight away. Certain eIDs may require an additional identity check for signing with QES. 

A growing number of people in Europe have a verified electronic identity (eID). By integrating different eID providers, Skribble gives millions of people instant access to digital signatures.

All identification options at a glance.

"The investment in Skribble is the perfect complement to our engagement with SwissID. Both solutions multiply their added value through integration. An ideal symbiosis and prime example of cooperation in the Swiss technology ecosystem."
Thomas Kühne, Head of IT at the Group Mobiliar


The simple electronic signature (SES) and the advanced electronic signature (AES) are legally valid for all contracts for which the law does not prescribe a specific form (contracts without the written form). You use the qualified electronic signature (QES) for contracts with a written requirement or to meet internal compliance requirements. Learn more about the three e-signature standards.

With SES, the e-mail address is used to identify the signer. The e-mail address must be confirmed by clicking on a link that is sent to the corresponding e-mail address.

The legal identification requirements are not the same. QES is the highest standard and is equivalent to a handwritten signature. The identification requirements for QES are precisely defined by the law. With SES and AES, providers have more freedom. When selecting identification procedures for SES and AES, Skribble pays attention to simplicity of use and maximisation of legal weight.
