EUDI Wallet Use Cases

What EUDI Wallet Use Cases Cover

eudi wallet use cases are the real-world interactions that turn the European Digital Identity Wallet from a policy concept into a working trust path. They are the moments where a holder presents identity data, attributes, or signatures to a relying party that must verify them under eIDAS 2.0 rules.

At a practical level, use cases range from proving who someone is, to sharing a specific attribute such as age, address, or a professional qualification, to producing a qualified electronic signature or an attestation. The security value comes from reducing ad hoc identity sharing and replacing it with cryptographically verifiable presentations.

Typical Wallet Use Cases

The most common wallet use cases are identity proofing, selective attribute disclosure, and qualified trust interactions. A user may present a PID, a driving licence, a diploma, or an organisational credential, depending on what the relying party is entitled to request and verify.

These use cases matter because they are not all the same from a trust perspective. Some rely on simple identity assertions, others depend on the issuer, the wallet, and the verifier all agreeing on format, signing, and validation rules. The Digital Identity, eID and Identity Wallets Guide is the best starting point for the wallet model behind those interactions, while the eIDAS 2.0, EU Digital Identity Framework defines the legal and trust framework that makes the use cases valid across Member States.

For relying parties, the practical question is not just “can a wallet present data?”, but “can this specific presentation be accepted, verified, and minimized for the stated purpose?” That is why presentation design, verifier rules, and trust framework alignment are central to wallet use cases rather than optional extras.

Identity, Attributes, and Signatures

EUDI Wallet use cases usually fall into three broad patterns. First is identity proofing, where a party needs confidence that the holder is the right person. Second is attribute disclosure, where only a specific claim is needed, such as “over 18” or “licensed professional.” Third is signing, where the wallet is used to create a qualified electronic signature or another trusted signed action.

These patterns differ in assurance and in what must be checked. Proofing and onboarding style cases require strong issuer confidence and careful fraud resistance, while attribute-based cases benefit from selective disclosure so the wallet reveals only what the transaction requires. Signing cases add the need for robust key control and clear reliance on the signature’s legal effect.

The SD-JWT and SD-JWT VC Guide helps explain how selective disclosure supports attribute-centric wallet use cases, while the Wallet Unit Attestation and Device-Bound Keys Guide covers the device and key binding assumptions that protect higher-assurance presentations.

Trust Framework and Relying Party Expectations

Wallet use cases only work when the relying party knows what it can trust, what it must verify, and what it is not allowed to assume. That includes wallet registration rules, issuer trust, verifier checks, revocation handling, and the legal meaning of the presented credential or signature.

In practice, this means use cases are shaped as much by policy as by technology. A wallet can only solve a business problem if the verifier, issuer, and trust framework agree on the exact data type, assurance level, and acceptance conditions. The Relying Party Integration with Digital Identity Wallets Guide is useful when you need to understand what relying parties must do to accept wallet presentations safely.

Because these use cases cross organisational boundaries, they also depend on standardised presentation flows and stable verification expectations. Without those, the wallet becomes a fragmented integration point rather than a reusable trust layer.

Operational Considerations for Real Deployments

The main operational challenge is that “wallet use case” sounds simple, but each one has different verification, assurance, fraud, and user-experience requirements. An age check is not the same as a regulated signing workflow, and a professional credential is not the same as a general identity assertion.

Organisations should treat each use case as a distinct trust design: define the minimum claim needed, the issuer source of truth, the verifier checks, and the failure handling if the wallet, issuer, or presentation channel is unavailable. The eIDAS 2.0 and the European Digital Identity Framework Guide is useful here because it ties those operational choices back to the obligations in the framework.

Where fraud resistance matters, the use case design must also account for replay, presentation phishing, and over-collection of data. That is why good wallet programmes define the use case first, then the control set, rather than assuming one generic wallet flow will fit every transaction.
