TL;DR: 63% of consumers are more likely to use the EUDI Wallet if it lets them share only what is needed, rising to 74% among Gen Z and 70% among Millennials, according to IDnow; it frames selective disclosure as the adoption lever, not just a privacy feature. Minimum-data design becomes the conversion control when verification friction and over-collection drive abandonment.
Editorial analysis by NHI Mgmt Group, based on content published by IDnow: “The Identity Gap: Privacy vs Compliance. Why Selective Disclosure Is the EUDI Wallet’s Most Powerful Feature”.
Key questions
Q: How should identity teams design onboarding when selective disclosure is available?
A: Identity teams should request only the verified attribute needed for the transaction, not the full source document.
Q: Why does selective disclosure improve both privacy and conversion?
A: It improves privacy because it reduces unnecessary data exposure, and it improves conversion because users are more willing to complete verification when the request feels proportionate.
Q: What is the biggest onboarding mistake with wallet-based identity verification?
A: The biggest mistake is asking for document-level identity when attribute-level proof would satisfy the purpose.
Practitioner guidance
- Design for attribute-level proof Replace document upload steps with requests for the single verified attribute the transaction actually needs, such as age or residency, and remove fields that are not required for the business purpose.
- Map every data field to purpose Document why each requested attribute is needed and delete any field that cannot be justified by the transaction purpose, legal basis, or fraud-control requirement.
- Measure abandonment caused by over-collection Track where users drop out after being asked for data that exceeds the stated purpose, then compare those steps against your completion metrics and complaint trends.
Bottom line: Selective disclosure matters because it turns identity verification from full-document collection into attribute-based proof, which reduces unnecessary exposure.

Selective disclosure is a conversion control disguised as a privacy feature. The article’s core insight is that consumers reward verification flows that expose only what is necessary. That matters because identity teams often treat data minimisation as a legal constraint, when in practice it is also a growth and completion lever. For practitioners, the lesson is to measure unnecessary data demand as a failure mode in onboarding design.
A question worth separating out:
Q: How do GDPR data minimisation and EUDI Wallet design work together?
A: They work together when the identity flow is built so only necessary personal data is requested, transmitted, and stored. In practice, that means the system should prove the needed condition without collecting unrelated attributes. When architecture enforces that rule, compliance becomes a property of the flow, not a manual policy.
