What is an Electronic Signature?

The European Union defines three types of eSignature: simple (SES), advanced (AES) and qualified (QES). Each type provides a different level of proof of identification and legal validity for the purpose of approving or executing a document transaction. Electronic signatures are portable and are supported by a technology that ensures their authenticity: all EU Member States conform fully to the latest regulations governing their legal effectiveness.

What is the Qualified Electronic Signature (QES)?



A Qualified Electronic Signature is based on a qualified certificate and is generated by an IT procedure that ensures the authenticity, integrity and non-repudiation of electronic documents.

Identification process

The QES certificate is issued by a qualified trust service provider only on completion of a specific online identification process that proves the real identity of the signatory.
