Step by step

By law, the qualified signature is equal to the handwritten signature throughout Europe. With its unique interface, sproof sign makes it possible to sign contracts with various qualified signature providers. This is a huge advantage when obtaining and issuing legally valid signatures.

We would like to show you this, using an example.

Once you are logged in, you can upload a document on the top right.

In the first step I would like to sign qualified myself.

I open the tab "Self sign", then I click on "Type of signature" and filter for the options to sign qualified. If you have a User+ license with sproof sign, you have the option to identify and use sproof sign's standard QES signature. In this example, our user only has a User license.

But: Both you and the people you invite to sign always have the option to use any other qualified signature for which you or your business partner:s have already identified themselves.

A large proportion of EU citizens already have an identification with a trust service provider.

In this example: Thomas, as an Austrian citizen, has the widely used cell phone signature, or ID-Austria. He can therefore search directly for this provider or also filter by his country.

We select the ID Austria for this document. We place a signature card on the document and click on "Sign now".

A login window for ID-Austria appears and you log in with your corresponding access data.

Then you enter the second factor typical for the qualified signature to confirm your identity. This was sent by SMS.

Surely the document was signed legally valid.

The same works with many other signature providers. When you send out a document for qualified signature, your counterpart will of course have the same providers to choose from.

You can check all the signatures affixed to the document and see who is the issuer of the signatures. You can find a dedicated tutorial on how to verify digital signatures here .

With the QES & eID Hub, it is possible to obtain qualified signatures throughout Europe in a very low-threshold and barrier-free way thanks to sproof sign. We are continuously updating this interface and integrating more signature providers step by step.

We wish you much joy and many uncomplicated signature processes.
