While national eIDs are implemented in most of the Member States, national eID Schemes are in developing phase in Bulgaria, Cyprus, Czech republic, France, Greece, Italy, Poland, and Romania.

EUCARIS has to be put in place by all Member States as an exchange infrastructure in order to facilitate secure data exchange on cross-border level.

While national eIDs are implemented in most of the Member States, national eID Schemes are in developing phase in Bulgaria, Cyprus, Czech republic, France, Greece, Italy, Poland, and Romania.

According to eIDAS regulation (EU regulation 910-2014), cross-border recognition of national eIDs will be mandatory from September 2018. However, it was not mandatory at the time of scenario development.

National information systems are fundamental base for decentralised cross-border OOP implementations. Therefore, the information systems have to connect with existing modules that enable cross-border operation and data exchange (e.g. with mapping tools).

The eDelivery has to be implemented in this area to facilitate secure data exchange that is fundamental base for the OOP implementation.

eDelivery exists as a EU building block to facilitate secure data transaction in cross border as well as cross-domain matters; however, it has to be implemented in the this area.

Further development of eID to facilitate confirmation of students' educational status as well as educational data exchange, could leads to elimination of ESC and further simplification of the scenario. Then eID could be enough for identification and authentication of students as well as verification of their educational status.

Unique identification for subjects such as students is needed to facilitate efficient identification and authentication. While national eIDs implemented in most of the Member States, national eID Schemes are in developing phase in countries such as Bulgaria, Cyprus, Czech republic, France, Greece, Italy, Poland, and Romania.
