What Is the EU Digital Identity Wallet?
The EU Digital Identity Wallet (EUDI Wallet) is a digital wallet on the smartphone of every EU citizen. It contains cryptographically secured proofs of personal identity – national ID, driver's license, educational credentials, and in the future also event tickets.
The legal basis is the revised eIDAS Regulation (eIDAS 2.0), which entered into force in 2024. All 27 EU member states are required to provide their citizens with a compatible wallet by 2026.
In short: The EUDI Wallet is the digital passport of the future – except it doesn't just contain your identity, but also tickets, certificates, and access credentials.
How Does the EUDI Wallet Work Technically?
The wallet is based on the international standard ISO 18013-5, originally developed for digital driver's licenses. All credentials are stored as mDocs (mobile Documents) – cryptographically signed data packages that can be verified offline.
The Three Core Principles
- Cryptographic signature: Every credential carries an ECDSA signature from the issuer. Forgeries are mathematically impossible.
- Offline verification: The scanner verifies the signature locally, without an internet connection.
- Device binding: An mDoc is bound to the device on which it was issued.
OpenID4VCI – The Issuance Process
Issuers deliver credentials to the wallet via OpenID for Verifiable Credential Issuance (OpenID4VCI). This protocol is an open standard and ensures that every compliant wallet can receive credentials.
Timeline: When Does the EUDI Wallet Arrive?
- 2024: eIDAS 2.0 enters into force. Pilot programs launch in several EU countries.
- 2025: Major reference implementations are tested publicly.
- 2026: All member states must provide the wallet. Mandatory acceptance by public authorities.
- 2027+: Broad adoption in private sector applications – ticketing, hotels, age verification.
Entryix is already compatible today. Organizers using Entryix now have a head start of years when the mandatory rollout arrives in 2026.
What Does the EUDI Wallet Mean for Event Organizers?
Tickets are stored as device-bound mDocs directly in the attendee's wallet. At the entrance, an Android device scans the credential – verification takes under 1 second, fully offline. This means: no forgeries, no duplicates, no black market.

Do Attendees Need the EUDI Wallet?
In the current beta, attendees receive cryptographically signed QR codes via email or WhatsApp – no wallet app required. Native EUDI Wallet integration is planned for Q1 2026.
