Handy-Signatur app

Speed-sign warrants convenient and quick signing of documents


The mobile solution developed by A-Trust in collaboration with Austria's Federal Chancellery, T-Mobile and A1 sets a completely new standard in user-friendliness and security for digital signature applications. The free mobile phone signature app for Android, iOS, Windows Phone and BlackBerry, digital signing is even easier and quicker thanks to the innovative speed-sign procedure: the application uses a QR code to ensure distinct and secure authentication in an application – once the user has entered the password − and the mobile phone is informed of this at the same time by means of push notification. All users need to do is focus their smartphone camera onto the QR code on the screen to verify their identity in a convenient and secure manner.
