European Commission
From November 2019, European citizens can use national eID schemes from 6 EU countries across borders, thanks to the eIDAS Regulation. Member States are now obliged to recognise the German National Identity Card and Electronic Residence Permit, the Italian eID means of SPID (Public System of Digital Identity), six Estonian eID means (ID card, RP card, Digi-ID, e-Residency Digi-ID, Mobiil-ID, Diplomatic identity card), the Spanish DNIe, the Luxembourgish National Identity Card and the Croatian Personal Identity Card (eOI) when citizens from other countries want to use their online public services. Businesses can also benefit from this cross-border recognition of electronic identification as the use of eID under eIDAS is open to the private sector.
