Three things worth knowing about this signature
Works across Europe
This is not a local Austrian service. It rests on the EU eIDAS Regulation (No. 910/2014). Signed in Vienna — valid in Berlin, Warsaw and Rome. Every EU country is obliged to recognise such a signature.
Qualified, not just «electronic»
A scanned or photographed signature is not a signature in the legal sense. Under Article 25 of eIDAS, a qualified signature (QES) carries the same force as a handwritten one. It is the highest level of electronic signature in the EU.
Official A-Trust registration authority
We have completed A-Trust's training and certification and operate under a current Registration Authority agreement. A-Trust is the Austrian qualified trust service provider: it issues the certificate, while we carry out the official identification of the person.
What this means in plain words
It is your personal signature, living in your phone. You use it to sign contracts, applications and invoices — in seconds, without leaving your chair. The certificate is valid for 5 years and the number of signatures is unlimited. Issuance through our registration authority is free.

What about Ukraine
EU signatures are recognised in Ukraine as equivalent to a handwritten one — since 1 January 2023, and permanently since 3 October 2024 (Cabinet of Ministers Resolution No. 1131). Ukrainian banks accept them too. You can sign contracts, invoices and acceptance protocols with Ukrainian counterparties.
