The eIDAS Regulation (eIDAS stands for "Electronic Identification, Authentication And Trust Services") is a regulation on electronic identification and trust services for electronic transactions in the member states of the European Union. eIDAS represents a genuine legal innovation whose stated purpose is to promote the development of digital applications in Europe. The heart of this article law, the Trust Services Act (VDG), contains all the necessary regulations for the use of digital signatures. The new EU regulation enables a new, simplified procedure for electronic signatures. Here, the components for creating the signature are not stored on a card, but in a secure IT environment of a qualified trust service provider. This means that the electronic signature can also be triggered remotely, for example using mobile devices such as tablets and smartphones.
