This week, EUDIW Unfold (@france_identite) is hosting interoperability testing for EU Digital Identity Wallet (@EUdigitalID) infrastructure, and we are participating with LutraID for the first time. 👨‍💻

The main focus of this testing is the verification of age credentials, while also covering PID and the issuance of these credentials across OpenID, mdoc, SD-JWT, and other key components of the EUDI ecosystem.

Interoperability is one of the main goals of the EUDI Wallet, and initiatives like this are essential for bringing different projects, wallets, issuers, and verifiers together in a real testing environment to see whether solutions are interoperable with each other.

Great to be part of the initiative and looking forward to the results and outcomes of the event!

Denmark just launched its @EUdigitalID 🇩🇰

The country has launched AltID, a national digital identity app that will serve as its digital identity wallet and, among other things, enable privacy-preserving proof of age and identity, both online and in person.

As the end-2026 EUDI Wallet deadline approaches, governments, public services, and businesses across Europe are starting to prepare for a new way of verifying identity, attributes, and credentials.

Which EU country is next? 👀

Meet the LutraID Showcase Series 🔍

We’re excited to launch the LutraID Showcase Series: a series of real, hands-on demos showing exactly how the @EUdigitalID (EUDI Wallet) ecosystem will work in everyday life.

From secure document issuance to seamless verification across different platforms, there’s no better way to demonstrate what the user journey will actually look like.

This week, we start with the foundation: issuance of the Person Identification Data (PID) – the first step of your digital identity.

More episodes coming in the next weeks.

Stay tuned and get ready to see the future unfold ✨

🔧 Behind the scenes: two powerful digital document formats that are powering the @EUdigitalID (EUDIW)

mDoc (ISO/IEC 18013-5) is the standardized high-assurance format that uses a compact CBOR-based structure and the Mobile Security Object (MSO) for strong cryptographic security. It is already widely adopted in the United States for mobile driver’s licenses (mDLs) and excels in proximity scenarios (BLE, NFC) with efficient selective disclosure and offline support.

SD-JWT VC (IETF) builds upon the widely adopted JSON Web Token (JWT) standard, adding built-in selective disclosure through salted hashes, strong cryptographic key binding, and seamless integration with web technologies and OpenID flows - making it ideal for remote verification.

Both formats are central to eIDAS 2.0 for Person Identification Data (PID) and other types of digital documents (EAAs). They give citizens true data minimization - sharing only what’s needed, when it’s needed.

At LutraID, we are actively working on issuance, wallet integration, and verification for both mDoc and SD-JWT VC.

🔍 It looks like the first explorations of ZKPs in the @EUdigitalID (EUDIW) are slowly taking shape.

The first integrations of zero-knowledge proofs (ZKPs) are now appearing in the EUDIW libraries, with ZK circuits being built in the @NoirLang programming language from @aztecnetwork . ZKPs are cryptographic methods that enable proving statements without revealing the underlying data.

EUDIW was designed to keep personal data securely stored locally in the user’s mobile wallet. This gives individuals true self-sovereignty and full control over when and what they share.

Adding ZKPs takes privacy even further: it minimizes data disclosure, reduces linkability across multiple presentations, and strengthens user privacy while keeping the wallet easy to use.

A meaningful step forward for privacy-preserving digital identity. 🔒

🌍 Another use case spotlight: Vehicle Registration Certificate

Say goodbye to old, faded paper vehicle documents in your glove box. The @EUdigitalID (EUDIW) will let you store a secure digital Vehicle Registration Certificate (VRC).

It proves your vehicle’s registration and legal compliance with national and European road rules.

Key benefits:
- Much easier to carry and access anytime
- Instant, secure sharing with police, insurers, or when selling or renting the vehicle
- No need to manually copy data onto other physical documents when sharing information

There will be a strong focus on delegation, making it easy to share the VRC with family members or other drivers while keeping full control (this will be very interesting to explore!).

We will no longer have to worry about carrying yet another document with us when going for a drive. 🚗

What are the key dates for eIDAS 2.0 and the future of digital identity ( @EUdigitalID ) in Europe? 🇪🇺

In December 2024, the first implementing acts for the European Digital Identity Wallet (EUDI Wallet) were introduced, defining the technical standards and framework needed to make the system work in practice. This is an important distinction. While the regulation itself (eIDAS 2.0) entered into force in May 2024, these implementing acts are what actually enable real-world deployment.

By the end of 2026, every EU member state must provide at least one EUDI Wallet to citizens, and public sector services must accept it. This marks the transition from regulation to real infrastructure and availability across Europe.

By the end of 2027, adoption will expand broadly across the private sector, but it will be mandatory only for specific regulated sectors and designated platforms. Industries such as finance, telecom, and energy, as well as very large online platforms (VLOPs), will be required to accept EUDI Wallets for identity verification upon user request.

In practice, 2025–2026 will be a build and rollout phase driven by standards and pilots, while 2027 onward marks the shift to full-scale adoption. Now is the time for companies to prepare, understand the upcoming changes, and start exploring how digital identity will impact their products and services 📊

As the @EUdigitalID rollout gets closer, we're seeing a rapid expansion of real-world use cases and digital document types. 🔐

Person Identification Data (PID), driving licences, insurance documents, payment authorizations, the European Parking Card (EPC), e-Prescriptions, Digital Travel Credentials (DTC), and many others.

Each use case defines document schemas, roles of entities and organizations, trust frameworks, and the foundations needed to ensure legal validity and interoperability. 🌍

Another milestone achieved: Issuance of Mobile Driving License (mDL) in mDoc format 📱🎉

Check out the credential being received in the @paradym_id wallet!

[Lutra Labs 🦦 @lutralabs_]

As the @EUdigitalID takes shape, it helps to understand that not all digital documents are the same. 🔐

The main difference comes down to who issues the document and what level of assurance and legal effect it carries. In the EUDI Wallet ecosystem, the key document types are EAA, QEAA, and Pub-EAA. Alongside these, the wallet also contains PID (Person Identification Data), which is used to establish identity itself rather than to attest specific attributes.

EAA stands for "Electronic Attestation of Attributes". These can be issued by a wide range of private sector entities and are suitable for lower-assurance use cases, such as membership cards, tickets, or other everyday digital proofs. They can still serve as evidence, but they do not carry the same legal effect as a paper document.

QEAA stands for "Qualified Electronic Attestation of Attributes". These are issued by trust service providers that meet additional regulatory and compliance requirements. Typical examples include diplomas and mobile driving licences. A QEAA has the same legal effect as a paper attestation, which gives it the highest level of assurance and strong cross-border trust.

Pub-EAA refers to an "Electronic Attestation of Attributes issued by or on behalf of a public sector body", based on authentic public sources. These credentials are tied to official government records, such as proof of residence or other state-backed attestations. Like QEAAs, they have the same legal effect as lawfully issued paper attestations. 🏛️

A simple way to think about it:
- EAA = useful digital proof, lower assurance
- QEAA = qualified proof, highest assurance
- Pub-EAA = official public-source proof, high assurance tied to government records

The real opportunity with the EUDI Wallet is not just to digitise documents, but to make their trust level explicit, portable, and interoperable across Europe. It is about creating a trust framework where each credential carries the right level of assurance for the right use case.

💼 The European Business Wallet will provide businesses with powerful software to simplify communication and interaction with other companies and government bodies across the European Union. It creates a unified, secure digital environment for cross-border operations.

Four main interaction models are planned:
• Business-to-Business (B2B): Businesses can digitally exchange data and documents while proving and verifying partner attributes in real time. This includes legal status, domain certificates, and other licenses.
• Business-to-Government (B2G): Businesses can seamlessly submit data such as tax filings, VAT declarations, customs documentation and public procurement submissions. This reduces bureaucracy and eliminates fragmented national portals and physical paperwork.
• Government-to-Government (G2G): Public bodies can exchange cross-border data like residency and company registration information. Communication happens over secure and encrypted channels.
• Government-to-Business (G2B): Governments issue licenses, permits, and certificates directly into business wallets. These credentials are instantly verifiable and reusable across the EU.

An important step toward standardizing secure digital communication between legal entities across the European Union. 🇪🇺
