Almost 100 Dutch municipalities participate in the biggest cross-border electronic identification project in the world. Enabling cross-border online access to public services allows them to benefit from decreased costs and paperwork, while increasing the level of service providers to citizens and businesses. As front-runners in the area of digitisation, they prepare the public sector for requirements of the eIDAS regulation 910/2014 in accepting the eIDs of member states of the European Union by September 2018.
