Mobile phone signature

Citizens are able to choose between two different citizen card options. The first is the well-known card-based option, in which for example the e-card is activated as a citizen card. The other is a mobile phone solution called the "mobile phone signature".

The mobile phone signature (citizen card function on the mobile phone) was developed with support of the EU Commission in the large EU pilot project on interoperability of electronic identities called "STORK" . It was activated during the last quarter in 2009. This solution makes it possible to use electronic signatures with a mobile phone. In contrast to the card-based citizen card, installing software and additional hardware (card reader) is no longer necessary.

The mobile phone signature functions similar to the solution banks use for e-banking. After successfully logging in with the access code (mobile phone number) and PIN, a TAN code is sent via SMS to the activated mobile phone. When the TAN code is entered in the respective application, a qualified electronic signature is created. This could also be a simple method for creating qualified electronic signatures on a mobile phone.

This signature would be, just like in the card-based solution, the legal equivalent of a handwritten signature, and could be used everywhere, not only for procedures with public administration, but also in business, for example, in e-banking. The mobile phone signature offers a user-friendly alternative to the well-known card-based citizen card, which is especially attractive for users who use it infrequently.
