What is a qualified electronic signature?


Comfortable and safe document signing

Certum Qualified e-signature is used for digital document signing. It is as legally binding as a traditional, handwritten signature. It is available in two variants: saved on a smart card placed in a reader, or stored in a cloud. Both forms are accepted by all key systems of Polish public administration. We will help you choose the option which best suits your needs.

Electronic signature helps you save time, increases the security, and is impossible to forge. A traditional signature does not give you such guarantee and it’s much less safe.
