The EUDI Wallet is the practical tool through which eIDAS 2.0 delivers on its core promise: a single, secure digital identity that works across all EU Member States. Where eIDAS 2.0 sets the legal and technical framework, the European Digital Identity Wallet is the implementation that puts those rules into action for citizens, residents, and businesses alike. The sections below answer the most common questions organizations have about how the two relate and what they need to do to prepare.

What requirements of eIDAS 2.0 does the EUDI Wallet directly fulfill?

The EUDI Wallet directly fulfills the eIDAS 2.0 requirement that every EU Member State must provide a digital identity solution to all citizens, residents, and businesses by 2026. It also satisfies the regulation’s demands for cross-border recognition, high assurance levels, and support for both public and private sector use cases under a single harmonized framework.

Under the original eIDAS regulation, Member States could notify their national eID schemes, but there was no obligation to do so. This created a fragmented landscape where some countries had strong digital identity infrastructure and others had almost none. eIDAS 2.0 changes that fundamentally. The regulation mandates that each Member State issue a wallet that meets a common technical standard, known as the Architecture and Reference Framework (ARF). This ensures that a wallet issued in one country is recognized and accepted in another.

The wallet also fulfills the regulation’s requirements around qualified electronic signatures, electronic attestations of attributes, and interoperability with trust services. In practice, this means the EUDI Wallet is not just an identity document replacement. It is a complete trust infrastructure tool that can carry verified credentials, enable legally binding signatures, and support a wide range of digital interactions.

How does the EUDI Wallet store and share identity data?

The EUDI Wallet stores identity data as verifiable digital credentials that are cryptographically secured and tied to the user’s identity. When a user wants to share information, they select exactly which data to disclose, and that data is transmitted directly to the receiving party in a verified and tamper-evident format.

Think of the wallet as a secure digital container. Inside it, users can hold a wide range of documents and credentials: a national identity card, a driving licence, educational qualifications, professional certifications, healthcare data, and more. Each credential is issued by a trusted source, such as a government authority or a recognized institution, and is cryptographically signed to prove its authenticity.

Sharing works through a selective disclosure mechanism. When a user needs to prove their age to access a service, for example, they do not need to share their full identity document. The wallet allows them to confirm only that they are above a certain age, without revealing their date of birth, address, or any other personal detail. This is a significant improvement over physical documents, which always expose more information than is strictly needed.

What is the difference between the EUDI Wallet and existing national eID schemes?

The key difference is scope and obligation. Existing national eID schemes vary widely across Member States and are not always accepted outside their home country. The EUDI Wallet, by contrast, is standardized across the EU, legally required to be provided by every Member State, and must be accepted by both public and private sector services throughout the EU.

Some countries, such as those in the Nordic and Baltic regions, already have mature national eID systems with high adoption rates. Others are still developing their digital identity infrastructure. The current situation means that a business operating across multiple EU countries may need to support several different national eID schemes, each with different technical interfaces and assurance levels.

The EUDI Wallet changes this by introducing a common standard. Once the wallet is fully deployed, organizations can connect to a single framework instead of managing multiple integrations. The wallet also extends functionality beyond traditional eID schemes by supporting electronic attestations of attributes, meaning it can carry far more than just a basic identity credential. It can hold professional qualifications, health data, and other verified information that national eID schemes typically do not support.

Which sectors are required to accept the EUDI Wallet?

Under eIDAS 2.0, certain categories of services are legally required to accept the EUDI Wallet. These include public sector digital services, banks and financial institutions for customer onboarding, telecommunications providers for SIM registration, and large online platforms that require user authentication. The regulation sets out these obligations to ensure broad adoption across the most critical service areas.

The sectors where acceptance is mandated reflect the areas where secure digital identity has the most immediate impact. For financial services, the wallet supports identity verification for account opening and strong customer authentication. For healthcare, it enables secure access to patient records and cross-border health services. For government services, it simplifies access to public administration across all Member States.

Large-scale pilot programs are already testing these use cases across the following areas:

1. Government services: Applying for official documents, filing taxes, and accessing social security information
2. Banking: Verifying identity when opening an account online, removing the need to repeatedly submit personal documents
3. Telecommunications: Proving identity for SIM card registration, reducing fraud for mobile operators
4. Healthcare: Accessing medical records and health services across borders
5. Education: Sharing academic credentials and qualifications in a verified digital format
6. Travel: Using digital travel credentials for seamless cross-border movement
7. Payments: Authorizing transactions using wallet-based identity and authentication

Organizations in financial services and healthcare in particular should treat wallet acceptance not as optional preparation but as a regulatory requirement they need to plan for now.

How does the EUDI Wallet protect user privacy under eIDAS 2.0?

The EUDI Wallet protects user privacy through a combination of selective disclosure, user consent, and a design principle that prevents unnecessary data sharing. Under eIDAS 2.0, the wallet is specifically required to ensure that users remain in control of what they share, with whom, and for how long. No data is shared without explicit user action.

Several privacy-by-design principles are built into the wallet architecture:

• Selective disclosure: Users share only the specific attributes needed for a transaction, not their full identity document
• No central tracking: The wallet architecture is designed to prevent any single party, including the wallet issuer, from tracking all of a user’s interactions
• User consent: Every data sharing event requires active confirmation from the user
• Minimal data exposure: Services can only request the data they are entitled to receive, not everything available in the wallet
• Pseudonymous identifiers: In some use cases, the wallet can present a pseudonymous identifier rather than a full identity, reducing the risk of profiling

This approach addresses a real limitation of physical identity documents. When you hand over a passport or ID card, you expose your full name, date of birth, address, and other details, even if the service only needed to confirm your nationality. The EUDI Wallet makes it technically and legally possible to prove what needs to be proven without revealing anything more.

When do organizations need to be ready for the EUDI Wallet?

Member States are legally required to make the EUDI Wallet available to citizens and businesses by 2026. Organizations in sectors that are mandated to accept the wallet need to be technically and operationally ready by the time their national wallet goes live. Given that 2026 is already here, preparation should be well underway rather than just beginning.

The timeline is tighter than many organizations realize. Large-scale pilot programs have been running since 2023 across 26 Member States, Norway, Iceland, and Ukraine, testing real-world use cases and refining technical specifications. The Architecture and Reference Framework is already in place, and implementing regulations covering areas such as protocols, interfaces, certification, and security have been adopted. The technical groundwork is largely set.

For organizations, the practical implication is that wallet readiness is not a future project. It is a current compliance and technology challenge. Organizations that wait for full national rollout before starting their integration work risk falling behind quickly. The earlier an organization understands the technical requirements and maps them to its existing systems, the smoother the transition will be.

Government agencies and public sector bodies in particular face early obligations, as government services are among the first categories required to accept the wallet. Private sector organizations, especially those in regulated industries, should use this period to audit their identity verification processes, assess their current infrastructure, and identify where wallet integration will be needed.
