Considering the importance of the eIDAS regulation, the current state of implementation of its stipulations both in the European Union and in our country, a comprehensive study of implementations and usage of digital identity tools (eID - electronic Identity) within the EU member states, revealing their peculiarities and the challenges related to the unitary integration required by eIDAS, proved both useful and necessary. The study is also justified by the fact that, on September 29, 2018, the eIDAS regulation became mandatory for each EU country stating that each EU country has to recognize both legally and practically - through interconnection in the eIDAS nodes network - the other EU countries notified digital identification schemes.
