The eIDAS-Node software is a sample implementation of the eID eIDAS Profile. It was developed by the European Commission with the help of Member States collaborating in the technical sub-committee of the eIDAS Expert Group. The eIDAS-Node software contains the necessary modules to help Member States to communicate with other eIDAS-compliant counterparts in a centralised or distributed fashion. The eIDAS-Node can either request (via an eIDAS-Node Connector) or provide (via an eIDAS-Node Proxy Service) cross-border authentication.
