EUDI Wallet Readiness

Start by separating ordinary account login from a wallet-relying-party interaction. eIDAS defines a European Digital Identity Wallet as an electronic identification means that lets the user securely store, manage, validate, and present person identification data and electronic attestations of attributes to relying parties, and also sign or seal by qualified electronic signatures or seals.

For a service provider, the readiness question is whether the service will request wallet data before granting access, verifying eligibility, completing onboarding, accepting a document, applying a pseudonym, or triggering a signature flow. If yes, the integration should be treated as an EUDI Wallet relying-party capability with a registered purpose, a defined attribute set, wallet-user approval, and a verifiable technical interface.

The Commission service-provider guidance says organisations that request data from EU Digital Identity Wallet users must register in the Member State where they are established. The same guidance lists practical obligations: provide registration information and contact details, specify the data requested and the purpose, request only the data specified during registration, and inform the Member State without delay when registration information changes.

The ARF explains the operational consequence: a relying party registers the attributes it intends to request from wallet units, and a wallet unit can verify whether the request is within that registered scope. If a registration certificate is available, the wallet can validate it; otherwise, the wallet can retrieve registered information from the relevant registrar's online service.

The Architecture and Reference Framework is the practical reference for wallet ecosystem roles, trust relationships, presentation flows, attestations, and certification concepts. It should be used as implementation architecture guidance, not as a substitute for the binding eIDAS text and implementing acts.

The Commission wallet implementing-regulation page identifies five implementing regulations covering integrity and core functionalities, protocols and interfaces, person identification data and electronic attestations of attributes, certification framework reference standards, and notifications to the Commission concerning the wallet ecosystem. A readiness file should map each wallet integration decision to the relevant source family rather than citing eIDAS in general.

Readiness should include a privacy review of every requested attribute. eIDAS requires wallet functionality that allows selective disclosure of data, and Implementing Regulation 2024/2979 describes selective disclosure as enabling the owner of data to disclose only parts of a larger data set so the receiver obtains only what is necessary for the requested service.

The ARF treats excessive attribute requests as a specific ecosystem risk. It identifies three practical mitigations: selective disclosure and user control, mandatory relying-party registration of intended requested attributes, and embedded disclosure-policy enforcement by attestation providers. The service design should therefore show the user which data is requested, why it is requested, and whether the request matches registered relying-party scope.

A useful EUDI Wallet readiness record should prove more than technical connectivity. It should show that the organisation knows its role, has registered the intended attributes where required, can authenticate its relying-party instance, has limited data requests to the registered purpose, and has tested user approval, logs, fallback routes, and revocation or change handling.

For service-provider integrations, evidence should be reviewable by legal, privacy, security, architecture, product, and operations teams. For wallet providers or component providers, the evidence set is broader and should include certification, wallet-unit integrity, trusted-list or List of Trusted Entities dependencies, and incident or breach handling responsibilities.
