What is a qualified electronic signature (QES)?
In Switzerland and Europe, electronic signatures are classified according to the ZertES and eIDAS standards as simple electronic signatures (SES), advanced electronic signatures (AES), and qualified electronic signatures (QES). The QES is legally equivalent to a handwritten signature and offers maximum security. This requires identity verification by a Qualified Trust Service Provider (QTSP), for example via a certified online procedure (video or auto identification) or personal identification on site.
When is the QES required?
QES replaces handwritten signatures when the written form is required by law or when a particularly high level of verifiability is required, for example:
- Employment contracts: For apprenticeship contracts and other employment contracts that require the written form.
- Credit agreements: For consumer loans, loan agreements, and financing agreements.
- Insurance contracts: In particular for life insurance or long-term policies where written form is recommended or required.
How does the QES work digitally?
The qualified electronic signature is based on state-of-the-art cryptography and strictly controlled identification processes:
- Identity verification by QTSP: The signatory is uniquely identified by a certified provider.
- Creating a digital signature: The signature is created using a qualified signature card or a secure cloud service.
- Document protection: Every signature is tamper-proof and provided with a detailed audit trail.
- Legal compliance: QES meets the requirements of ZertES and the eIDAS Regulation, ensuring maximum legal validity.
Advantages of digital QES
QES offers maximum security and legal validity. It protects documents from manipulation and ensures clear identification of the signatory. It also ensures efficient, digital processing of contracts without media discontinuity.
