Electronic signature (QES)

What is a qualified electronic signature?

According to Article 14 para. 2bis of the Swiss Code of Obligations, a qualified electronic signature is equivalent to a handwritten signature. What constitutes a qualified electronic signature is governed by the Federal Act on Electronic Signatures (ESigA).
