There are three levels. They differ in how strictly the person signing is identified:
- Simple (SES): without additional identification. For documents without any special formal requirements.
- Advanced (AES): confirmation with a code sent by SMS. A mobile number must be recorded for each person signing.
- Qualified (QES): equivalent to a handwritten signature. Identification is carried out via the SwissSign Wallet app and requires a verified SwissID. You can get the SwissSign Wallet app free of charge for iOS and Android at https://www.swisssign.com/identitaeten/wallet.html.
The signature type can no longer be changed after sending – choose it carefully. Detailed information about the signature types and their legal validity can be found in the SwissSign FAQ: https://www.swisssign.com/support/faq/signaturen.html.
