Qualified & legally sign throughout Europe.

Our eID hub: We have integrated providers for qualified electronic signatures (QES) across Europe. This is a huge advantage when obtaining and issuing legally valid signatures.

Interoperable qualified signing in Europe

Obtaining signatures digitally across countries can be time-consuming and tedious. For example, if you have to sign a document for one person from Estonia in a qualified manner and then later for another person from Germany, it may be necessary to obtain new identification each time. Although this process is not complicated, in practice it can be time consuming and unnecessary if done repeatedly.

sproof offers a solution to this and allows existing identifications to be used directly. Thus, when a document is signed with sproof, there is no need to go through a new identification process, but existing identifications, such as ID Austria, can be used directly.
