Advanced electronic signature

Advanced electronic signatures (AdES), are electronic signatures that are one level below the qualified electronic signatures issued to individuals. It is based on an Advanced Electronic Certificate. Technologically there is no difference between the two, but there is a difference in the process of authenticating the person when issuing the certificate and the level of authentication when signing. This signature is fully suitable for legal transactions, but is not suitable for communication with the State. 

The main difference is that the verification of the person when issuing the certificate does not need to be done in person or with another qualified certificate. 

The second factor used in signing may not have as high a level of security. NFQES Authenticator or SMS can be used.

The mandate certificate is, in the sense of §8 par. 1 of Act no. 272/2016 Coll. , a qualified certificate for an electronic signature issued to an individual who is authorized to:

• by law or on the basis of the law to act for or on behalf of another person or public authority
• perform activities according to a special regulation
• perform function according to a special regulation

The individual to whom this type of certificate is issued is referred to as the mandate holder.

Thanks to the mandate certificate, it is possible to carry out legal acts electronically, which traditionally require a written form.

A qualified electronic signature is equivalent to a handwritten signature.

A qualified electronic signature certificate is required to create a qualified electronic signature.

A qualified certificate can only be issued by qualified providers of trusted services, such as NFQES/, s.r.o. .

In order to obtain a qualified certificate, it is necessary to verify your identity through an electornic identity card or by showing your passport.
