Digital Identity Wallet for Payments – A joint paper by Smart Payment Association and Secure Identity Alliance – October 2025
Digital Identity Meets Payments: Promise, Pitfalls, and the Pragmatic Path Forward
As Europe advances toward deploying the EU Digital Identity (EUDI) Wallet, many see payments as the killer user case — but is it really that simple?
A new white paper by the Smart Payment Association (SPA), in collaboration with the Secure Identity Alliance (SIA), cuts through the hype.
Authored by Alain Martin and Debora Comparin, “Digital Identity Wallet for Payments” examines how the EUDI Wallet could interact with Europe’s payments ecosystem — and what it will take to make that work.
Read the paper to learn:
- What eIDAS 2 and PSD2/PSR mandate
- Why KYC and customer onboarding are the most promising early use cases
- Why SCA is a challenging use case
- How the EUDI Wallet can enrich payment information transmitted to the merchant
- How existing payment infrastructures can enable payment functionality within the wallet without reinventing the wheel
If you’re involved in digital identity, payments, or financial innovation, this white paper offers a grounded, expert view of what’s truly possible — and what’s not — when identity meets payments.
