An ID card for the Internet – The new German ID card with “electronic proof of identity”

The personal ID card is a document carried by most Germans, but rarely used. This could change in the future: According to the new law on identification cards and electronic proof of identity (Gesetz über Personalausweise und den elektronischen Identitätsnachweis, PAuswG), the ID card, with its proof of identity, will gain a new functionality, making it applicable for diverse Internet transactions. Functionally, the electronic proof of identity corresponds to existing non-electronic personal proof of identity guidelines in legal and business connections. However, its concrete, technical application opens up many issues regarding contracts and data privacy laws. On both the legal and the technical level, the German approach departs from other European countries, as it strictly distinguishes the electronic proof of identity from the electronic signature function, which the new ID card also provides. It remains to be seen whether the various projects of the EU Member States will become legally and technically interoperable in the near future.
