Mobile Phone Signature

With the mobile phone signature, users thus have a digital ID as well as the electronic signature function at their disposal

The mobile phone signature is the mobile variety of the citizen card on the mobile telephone that it has been possible to use in eGovernment since 2009. With the mobile phone signature, users thus have a digital ID as well as the electronic signature function at their disposal. Software installations and additional hardware (card readers) are no longer required, in contrast to the card-based citizen card.

Businesses also benefit in many areas from the use of the mobile phone signature, for instance, in the signing of purchase contracts, applications to authorities or in the usage of the mobile phone signature in the communication with their customers.

The mobile phone signature also offers considerable alleviation in the fulfilling of different reporting and information obligations towards the administration. For businesses, different reporting and information obligations towards the administration mean a high amount of time and money. 200 million times a year, businesses in Austria meet one of the 5,000 information obligations under federal law towards authorities or third parties. The mobile phone signature is a key for businesses in order to register at the Business Service Portal – the central one-stop business portal of the federal administration – to retrieve customized, company-relevant information and to use the pooled eGovernment applications (e.g. official channels) of the federal government with single sign-on function conveniently and securely via the Internet.

Optimum conditions can thus be created for businesses and modern, efficient and digital administration processes made possible. This also strengthens the economic location and underlines Austria’s forerunner role in eGovernment.

The other applications or procedures that can already be carried out conveniently and particularly securely using mobile phone signature include for instance the signature of e-invoices, participation in electronic tendering or FinanzOnline (for instance the sending of VAT, income tax and corporation tax declarations online). In addition, the mobile phone signature also permits a secure communication to customers (e.g. through secure access to company services or the delivery to the customer with proof of delivery).

The mobile phone signature app

In addition, since mid-2016, there has been a mobile phone signature app that constitutes an even more convenient possibility for using the mobile phone signature. In the process, the TAN is not communicated by SMS but in a previously installed app. Another possibility is the “speed-sign” function in the app. Here, the triggering of the signature is done by the scanning of a QR code and thus replaces the manual entry of a TAN. The mobile phone signature app is cryptographically tied to the respective appliance, which increases the security of the solution further. In the medium term, the app solutions will replace the SMS-TAN in most cases.

The use of the mobile phone signature by means of an app is automatically supported by all services that use the mobile phone signature.
