EU digital IDs go cross-border

In Italy, a motorist can already show a digital driving licence to the police. In Greece, a citizen can pull up a passport inside a government app. In Poland, a document can be signed electronically from a phone. What still breaks down is the moment the same person crosses a border.

That Italian licence does not automatically help you rent a car in Spain. A Greek digital passport does not replace border documents abroad. A Polish digital credential will not necessarily open a bank account in Belgium. This gap between national convenience and European use is what the EU’s digital identity wallet is meant to close.

A secure folder on your phone, not a government database

The EU Digital Identity Wallet, created through Regulation 2024/1183, is best understood as a secure folder on your phone for verified facts about you. A government agency or authorised body signs a digital credential confirming one specific thing: that you hold a valid driving licence, that you are over 18, or that your diploma is genuine.

You keep those credentials on your device and decide what to share. For Malta, where public services have moved steadily online but where trust in institutions is never a small matter, that distinction is important. The wallet is not supposed to be a single EU identity database sitting somewhere in Brussels.

The useful mechanism is selective disclosure. Instead of handing over a passport scan to a car rental company, you share only the verified statement that you have a valid licence. Instead of giving a website your name, address and date of birth to prove you are an adult, you share a yes-or-no proof of age.

The European Commission is building privacy-preserving age verification on that same principle. Germany’s official EUDI-Wallet site also stresses local storage and user control. The intended model is closer to carrying verified cards in a locked phone folder than joining a surveillance register.

National apps prove the demand

Several member states are already showing why people would use this. Poland’s mObywatel is the most advanced example: 7 million users have activated the digital driving licence alone (Gazeta). Since July 2026, the app has also offered a free electronic signature for everyday documents (PAP Mediaroom).

Greece’s gov.gr Wallet now includes the ordinary passport for domestic identification. Italy’s IT-Wallet offers a digital driving licence in app IO, legally valid for road checks inside Italy.

These are not niche experiments. They show that citizens will use digital identity when it saves them time at the counter, on the road, or in the kind of form-filling that has become part of ordinary life. Maltese readers will recognise the pattern: once a digital service works reliably, whether for tax, health records or public appointments, it quickly becomes the normal route.

But demand is not the same as interoperability. Poland’s own tech coverage notes that travellers still need a classic passport abroad. Greece’s digital passport works for identification at home but not for international border controls. Each wallet still belongs to its own island.

The hard part isn't technology

The legal framework is already there. The difficult part is turning it into acceptance. By late 2027, banks, websites and public offices across the EU may be expected to accept wallet credentials, not only national documents (Fintech Global).

That matters for Malta because cross-border identity checks are not marginal here. Financial services, remote gaming, fintech, tourism and a workforce moving in and out of the country all depend on proving who someone is, whether they are licensed, and whether a document can be trusted. A wallet that works across the EU could reduce friction. It could also shift compliance costs onto businesses that already live under tight anti-money laundering and know-your-customer rules.

Italy’s technical documentation describes its wallet as progressively aligning with the EU model. Even the frontrunners are still building towards the common system.

The privacy question cannot be brushed aside. German experts have warned about function creep and unclear liability after misuse (taz). A properly governed wallet should reduce data sharing compared with photocopying a passport for every transaction. A badly governed one could make identity checks normal in situations where anonymity used to be expected.

The result will depend less on the cryptography than on the rules around it: who can ask for which proof, what gets logged, what happens when something goes wrong, and how easily a citizen can refuse an unnecessary request.

Europe is trying to do for identity what payment networks did for cards. A Visa card works across borders because years of standardisation made the process boring. Digital identity is attempting the same move, from national apps that work at home to credentials that travel with you.

The technology exists. The law is written. The real test will come at the rental desk in Spain, the bank in Belgium, or the age-check website in Germany, when someone presents a proof issued somewhere else.
