Context
What the EUDI Wallet Is, and Why It Matters
The European Digital Identity Wallet is mandated by eIDAS 2.0 (EU Regulation 2024/1183). Every EU citizen is entitled to a EUDI Wallet for cross-border identification and document storage. The wallet architecture sits on two cornerstones — Person Identification Data (PID) and Qualified Electronic Attestations of Attributes (QEAA).
Wallet Components
What eMudhra Delivers
From PID issuance to relying-party integration, the EUDI capability stack is implemented end to end — with formats, protocols, and revocation flows matched to the EUDI Architecture and Reference Framework.
PID Provider
Person Identification Data
PKI-rooted issuance of person identification data — the foundational attestation on which all other credentials in the wallet hang.
QEAA Issuance
Qualified Electronic Attestations
Driving licence, diploma, professional qualifications, healthcare entitlements — each issued as a qualified attestation under a named issuer authority.
Wallet Backend
Document repository
Encrypted-at-rest storage for wallet-resident documents. Customer-controlled keys; provider can't read content.
Relying Party APIs
Bank, telco, government integration
OpenID4VP-based presentation APIs for relying parties to request and verify wallet credentials.
mDL
Mobile Driving License
ISO 18013-5 compliant mDL — the international standard for digital driving licences presentable both online and to physical scanners.
VC / VP Formats
W3C, SD-JWT, mdoc
Multi-format credential issuance and verification — W3C VC for ecosystem interop, SD-JWT for selective disclosure, mdoc for ISO 18013-5 alignment.
Revocation
OCSP / CRL
Credential revocation backed by eMudhra CA infrastructure — OCSP responder, CRL distribution, and status-list verifiable credentials.
Selective Disclosure
User-controlled
Citizen shares only the attributes needed — "I am over 18" rather than handing over a full date of birth and address.
Use Cases
Where EUDI Wallets Get Used
Cross-Border Travel
Replacing physical ID cards for intra-EU travel and check-in. Frictionless border crossing for citizens of issuing member states.
Bank Account Opening
Customer presents EUDI PID; bank skips manual KYC re-do. Faster onboarding, fewer fraud cases, regulator-recognised verification chain.
University Diploma Verification
Diplomas issued as QEAA, verifiable across EU member states. Employers and universities verify in seconds, no transcripts requested.
Professional Qualification
Medical licences, legal practice certificates, engineering credentials — portable across borders without manual recognition.
Age Verification
Alcohol sale, gambling, adult content — prove age without revealing birth date or full identity. Selective disclosure at its most useful.
Healthcare Entitlement
Cross-border health card recognition — e.g. EHIC presented as a wallet credential for medical care anywhere in the EU.
Beyond the EU
Non-EU Jurisdictions Adopting eIDAS-Compatible Architectures
Wallet architectures based on EUDI/eIDAS principles are spreading beyond Europe. The same component stack maps cleanly to GCC, APAC, and Indian Subcontinent contexts.
India
DigiYatra and DigiLocker overlay — mapping wallet-style credentialing onto India's existing identity infrastructure.
UAE
Alignment with UAE Pass — layering wallet-style credential presentation on the existing national digital identity service.
Singapore
Singpass extension — wallet-style attribute-sharing complementing the existing high-assurance national ID service.
