A qualified electronic signature (QES) has, pursuant to Regulation (EU) No 910/2014 (eIDAS), the equivalent legal effect of a handwritten signature. Under the e-Government Act, it is one of the methods of authorising (signing) an eSubmission. If it includes a qualified electronic time stamp, it has, pursuant to Act No. 305/2013 Coll., the legal effect of an officially certified signature (in the same way as a handwritten signature certified by a registry office or notary).
eSignature, i.e. a qualified electronic signature (QES), is one of the four types of electronic signatures distinguished by the eIDAS Regulation at EU level:
- qualified electronic signature (QES),
- advanced electronic signature based on a qualified certificate,
- advanced electronic signature,
- electronic signature.
In addition to the eSignature (QES), which all public authorities are required to accept, other types of electronic signatures are used on the portal, depending on whether the respective public authority accepts them.
