What is an Electronic Signature (eSignature)?

The European Union defines three types of electronic signature: simple electronic signatures (SES), advanced electronic signatures (AES) and qualified electronic signatures (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 the legal effectiveness of electronic signatures.

What is the Qualified Electronic Signature?



A Qualified Electronic Signature is an Advanced Electronic Signature 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.
