A number of building blocks offering basic capabilities exist that can be used to set up the technical system, such as the Connecting Europe Facility, established by Regulation (EU) No 1316/2013 of the European Parliament and of the Council, and the eDelivery and eID building blocks that form a part of that facility.
Tá cumais bhunúsacha ag roinnt de na bloic thógála atá ann cheana, ar féidir úsáid a bhaint astu chun an córas teicniúil a bhunú, amhail an tSaoráid um Chónascadh na hEorpa, a bunaíodh le Rialachán (AE) Uimh. 1316/2013 ó Pharlaimint na hEorpa, agus na bloic thógála r-Sheachadadh agus eID atá mar chuid den tsaoráid sin.
