Summary

• ACI Worldwide has joined the European Payments Initiative and will integrate Wero into its Payments Orchestration Platform.
• Wero runs on SEPA instant payment rails and is live for instant account-to-account payments in Belgium, France, and Germany.
• The move connects Europe’s instant-payments regulation, merchant acceptance, payments sovereignty, and competition with global card and wallet networks.

ACI Worldwide has joined the European Payments Initiative and will integrate Wero, EPI’s pan-European digital wallet, into its Payments Orchestration Platform, giving merchants and financial intermediaries another route to offer account-to-account payments across Europe.

The collaboration connects two parts of Europe’s payments agenda. Wero is designed as a European wallet running on SEPA instant payment rails, while ACI provides payment orchestration, instant-payment connectivity, and infrastructure used by banks, payment service providers, acquirers, fintechs, and merchants.

Wero currently offers instant account-to-account payments to consumers in Belgium, France, and Germany. EPI plans to expand the service to Luxembourg and the Netherlands in the coming months, while continuing to explore other markets. Online payments have been available to consumers in Germany and Belgium since autumn 2025, with French consumers expected to gain similar services this autumn. In-store payment options are planned for 2027.

Europe’s payments market remains fragmented across national schemes, cards, bank transfers, wallets, local payment methods, and global networks. That fragmentation creates cost and operational complexity for merchants selling across borders. It also leaves Europe heavily dependent on US-headquartered card schemes, digital wallets, and platform-controlled payment experiences for retail and e-commerce activity.

EPI was created by a consortium of European banks and financial services companies to build a more unified European payment system. Wero is the consumer-facing attempt to turn that ambition into a usable wallet for person-to-person transfers, e-commerce, point-of-sale payments, and future value-added services. Adoption, however, depends on merchant acceptance as much as bank backing.

ACI’s role is commercially important because payments orchestration platforms help merchants manage multiple payment methods, providers, routing choices, reconciliation processes, and fraud controls through a central layer. If Wero can be added through orchestration rather than integrated separately by each merchant, EPI gains a faster route into checkout acceptance.

The regulatory backdrop is favourable. The EU Instant Payments Regulation is designed to accelerate instant euro credit transfers across the bloc, requiring payment service providers that offer standard euro credit transfers to offer instant transfers as well. That creates better rails for account-to-account payment products, although rails alone do not create consumer habit.

Wero’s hardest test will be behaviour at checkout. Consumers use payment methods that are available, trusted, familiar, fast, and accepted by merchants. Wero has to compete with cards, Apple Pay, PayPal, local bank-payment habits, and other wallet experiences. A European policy rationale will not carry the product if conversion is weaker or refunds, fraud processes, and customer support feel unfamiliar.

Merchants will judge the wallet on cost, settlement speed, fraud exposure, refund handling, reconciliation, conversion rates, and operational reliability. Account-to-account payments may offer lower costs and faster settlement than some card-based transactions, but merchants will not accept friction in the customer journey merely to support a sovereignty agenda.

Banks and payment service providers have their own incentives. EPI’s proposition is tied to the idea that Europe should have payment infrastructure that is less dependent on non-European schemes and wallets. Payments have become part of digital sovereignty because they touch commerce, sanctions, platform power, identity, and financial resilience. ACI’s participation gives Wero more technical distribution, but the market will ultimately measure progress in transaction volume.

ACI says instant payment transactions in Europe are expected to rise from 17.2bn in 2023 to 38.6bn in 2028, accounting for 13% of electronic payments in Europe by that point. Those forecasts show growth in the rail, not certainty about which wallet or payment experience captures the volume.

The ACI-EPI agreement is a practical step in Europe’s attempt to turn instant-payment infrastructure into a mainstream commercial payment experience. The next phase depends on acceptance, consumer trust, bank participation, and checkout performance. Europe has built more of the rails. Wero now has to prove it can win the interface.
