for electronic signing

It is necessary that each signature can be attributed to a single person.
Therefore, Skribble requires the identification of the signatories.
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 options for contracts without written form:

E-mail address

In the case of the simple electronic signature (SES), the signatories 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.
Company e-mail address

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 (CH)
A mobile phone protrudes from the houses.
Swiss telecom providers are obliged to record the ID or passport of their customers before signing a contract. Anyone registering on Skribble with a Swiss mobile phone number can sign immediately with AES.

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.

Identification options for the qualified electronic signature (QES):

Identification Unlimited
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.
A representative of your company goes through a one-time training. Afterwards he can identify the signatories himself face-to-face. Suitable for companies with a large number of QES signatories.

Identification Direct
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 signatories enable the QES by having themselves identified online via video (EU) or face-to-face at an identification site (Switzerland). Suitable for individuals and companies with a small number of QES signatories.

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. You can find examples and more information at:

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.
