Identification methods

How do the identification methods for signing with QES under EU and Swiss law differ?

The identification of signers is required by law before signing with the qualified electronic signature (QES). However, the required identification method is defined by the respective jurisdiction.

  • Swiss law requires face-to-face identification on site or online identification (since 15 March 2022).
  • In the EU, the online identification is enough.

Therefore, signers usually choose the identification method of the jurisdiction according to which they are signing or the jurisdiction required by the document to be signed. In general, however, both methods of identification enable signing with QES with worldwide validity. Learn more.
