a.sign premium (Bürgerkarte)

Efficient and secure e-business


The web has become a permanent fixture of our private and business world. The possibilities for working with it rapidly, efficiently and at a favourable cost are practically endless. But what about the required security? Defences against phishing attacks, trojans and viruses play a growing role in most companies.


In shape for digital change

If you want your ordering system, your contract processing or notarization or also your requests to public authorities to be practically forgery-proof, then you need digital signatures. Wherever handwritten signatures are usually required, this electronic legitimation allows the efficient and forgery-proof transfer of important documents.

The signature card a.sign premium makes precisely this possible. Various chip cards, such as the a.sign premium card or the e-card, can be used as carrier medium. Optionally, a.sign premium can also be extended to include an identity link, thus becoming a full-fledged citizen card.


Installation of the free a.sign Client and the A-Trust citizen card software is recommended for use of the a.sign premium card.
The a.sign full installer supplies you with the basics in terms of signature software and instructions e.g. for signing Word and PDF files.
