Our Take
ACI is distributing EPI's plumbing, not solving fragmentation; Wero reaches three countries today and in-store payments won't ship until 2027.
Why it matters
Europe's instant payment infrastructure is mandated by regulation (EU Instant Payments Regulation, live January 2025), and ACI already connects banks across 11 central instant-payment systems. The Wero partnership extends that reach to merchants and PSPs, but the real tailwind is regulatory, not technical.
Do this week
PSP operators: audit your current instant payment rails and merchant wallet coverage against the EPI roadmap (Germany and Belgium live now, France autumn 2026, in-store deferred to 2027) to set realistic go-live dates for clients.
ACI becomes EPI principal member and integrates Wero
ACI Worldwide, a NASDAQ-listed payments infrastructure vendor, has joined the European Payments Initiative as a principal member and committed to integrating Wero, EPI's digital wallet, into its Payments Orchestration Platform. The integration will expose Wero to ACI's merchant and PSP customer base across Europe.
Wero launched in 2024 by a consortium of 16 European banks and financial services companies. It operates on SEPA instant payment infrastructure and currently offers account-to-account payments to consumers in Belgium, France, and Germany. Online payments are live in Germany and Belgium; French consumers gain access in autumn 2026. In-store payments are not expected until 2027, with subscription services planned for later.
ACI already operates the infrastructure backbone. The company powers 26 domestic and pan-regional instant payment schemes across six continents, including 11 central clearing systems, and reaches approximately 3 billion people through central banks, banks, and PSPs.
Regulation, not innovation, is driving adoption
The EU Instant Payments Regulation came into force in January 2025 and requires all Eurozone banks and PSPs to send and receive instant payments. This mandate creates demand for distribution, and ACI is supplying it. The company projects instant payment transactions in Europe will rise from 17.2 billion in 2023 to 38.6 billion by 2028, growing their share of electronic payments from 8% to 13% (per ACI's Prime Time for Real-Time report).
The partnership is a distribution win for EPI but does not itself solve Europe's payments fragmentation. Wero is one wallet in a continent where multiple domestic schemes and legacy payment methods remain entrenched. ACI's role is plumbing: connecting merchants and PSPs to Wero's network, not replacing existing infrastructure.
Merchant and PSP roadmap
Practitioners should map Wero's launch dates against their own go-live timelines. Online payment integration is available now in Germany and Belgium, with France following in autumn 2026. In-store capability does not arrive until 2027. If your merchant or PSP roadmap depends on in-store account-to-account payments, Wero is not yet an option and competitive products or wallet schemes may offer earlier entry.
ACI's platform adds Wero as one APM (alternative payment method) among many. The value is optionality: merchants and PSPs now have direct access to Wero without building their own integration. Whether adoption accelerates beyond early adopters depends on consumer adoption rates and merchant demand, neither of which ACI or EPI have disclosed.
