EU’s Digital ID Wallet Consortium Explores Payment Applications in White Paper

The European Digital Identity Wallet Consortium (EWC) has released a white paper exploring the integration of payment functionalities into the European Digital Identity Wallet (EUDI Wallet). The document provides a roadmap for leveraging the wallet as a tool for payment authentication and initiation, with a strong emphasis on biometrics and its role in enhancing security and user experience. This development follows Germany’s recent announcement to develop its own version of the EUDI Wallet, demonstrating growing momentum for digital identity initiatives across the EU.

The white paper positions the EUDI Wallet as a transformative solution for payments, leveraging existing technologies, including device biometrics, to meet regulatory requirements for Strong Customer Authentication (SCA). “Current best practices are secure and easy to use, leveraging device biometric and advanced fraud signals,” the document notes, highlighting the wallet’s potential to combine security with convenience. Biometrics, such as fingerprint and facial recognition, could enable frictionless payment authentication, driving consumer adoption.

A key innovation discussed is the wallet’s role as an alternative SCA method. Users would link their EUDI Wallet to a payment account or card during registration, allowing it to act as a “payment wallet attestation” during transactions. This attestation, combined with cryptographic proofs and transaction-specific data, provides a secure and reliable mechanism for authentication. By aligning with standards such as 3-D Secure (3DS) and leveraging advanced fraud detection signals, the wallet is expected to integrate smoothly with existing payment systems, similar to how Mastercard’s Identity Check program has implemented enhanced security measures.

The white paper also addresses significant regulatory and operational challenges related to authentication. It acknowledges the complexity of requiring payment service providers (PSPs) to establish agreements with multiple wallet providers for SCA purposes. Instead, the EWC proposes that banks maintain control over authentication decisions while relying on trusted proofs generated by the wallet. This approach ensures compliance while reducing the burden on PSPs to manage extensive outsourcing agreements.

Beyond authentication, the EUDI Wallet is envisioned as a versatile tool capable of holding payment credentials and other attestations, such as proof of income or age verification. These features have broad applications across e-commerce, in-store transactions, and regulatory compliance, such as meeting anti-money laundering (AML) requirements under EU financial regulations. “The EUDI wallet should adopt existing standards and be interoperable with existing payment infrastructure,” the authors stress, underscoring the need for compatibility with current systems like NFC-enabled POS terminals and EMV tokenization.

The white paper draws on lessons from successful digital identity initiatives like Sweden’s BankID and Belgium’s itsme. Both examples demonstrate the importance of intuitive user interfaces and high-frequency use cases to drive consumer adoption. Biometric authentication and seamless payment integration are likely to play a pivotal role in replicating these successes with the EUDI Wallet.

Interoperability is another critical theme. The document stresses the need for the wallet to align with industry standards while remaining adaptable to future technological advancements. For example, ensuring compatibility with EMV Contactless Specifications and ISO/IEC standards will enable the wallet to operate within existing payment ecosystems without requiring costly infrastructure upgrades.

While optimistic about the wallet’s potential to transform payments, the EWC emphasizes the need for further work to address issues such as liability frameworks, risk monitoring, and scaling operational processes. “Facilitating payments is an important use case for the EUDI wallet and is likely to drive consumer adoption,” the white paper states. However, realizing this potential will require a concerted effort from both public and private stakeholders.

By focusing on biometrics and robust authentication mechanisms, alongside a commitment to interoperability and regulatory compliance, the EUDI Wallet aims to redefine digital payments in the European Union. The white paper serves as both a call to action and a blueprint for addressing the challenges ahead, ensuring the wallet’s successful deployment across the EU by 2026.
