LONDON — The European Union unveiled plans Thursday for a digital ID wallet that residents could use to access services across the 27-nation bloc, part of a post-pandemic recovery strategy that involves accelerating the shift to an online world.

The European Digital Identity Wallet proposed by the EU’s executive commission is a smartphone app that would let users store electronic forms of identification and other official documents, such as driver’s licenses, prescriptions and school diplomas.

The bloc’s 450 million residents would be able to use the wallet to access public or private services both online and offline while maintaining control of their personal data.

Officials envision the wallet allowing a customer renting a car at an airport, for example, to complete the necessary ID checks and documents digitally and thereby skip the usual wait at an agency counter. Nightclub-goers could show the app to security guards at the door to prove their ages.

Other potential uses include opening bank accounts, signing apartment leases and enrolling in universities outside an individual’s home country.

The digital wallet “will enable us to do in any member state as we do at home without any extra cost and fewer hurdles,” Margrethe Vestager, the European Commission’s executive vice president for digital, said. “And do this in a way that is secure and transparent.”

Digital is a key part of the EU’s post-COVID 19 recovery package: A 750 billion-euro ($915 billion) stimulus fund includes benchmarks for member countries to spend one-fifth of the money on digital projects such as digitizing public administration.

Some EU countries already have their own national digital ID systems, and the wallet Brussels is developing would work with them. All EU residents would be entitled to one, but they won’t be mandatory, according to the EU Commission.

The commission plans to discuss the wallet with the EU’s 27 member countries and aims to get them to agree on technical details by the fall so pilot projects can begin.
