Europe's Payment Revolution: ACI and Wero Forge a New Alliance

OMAHA, NE – June 15, 2026 – In a move poised to reshape the European financial landscape, payments technology stalwart ACI Worldwide has announced a strategic partnership with the European Payments Initiative (EPI). The collaboration will see EPI’s pan-European digital wallet, Wero, integrated into ACI’s formidable Payments Orchestration Platform, a critical step in the ambitious quest to create a unified, sovereign payment system for the continent.

This alliance is more than a simple technical integration; it represents a calculated maneuver to accelerate the adoption of Wero, a project backed by 16 major European banks. By leveraging ACI's extensive network of merchants and financial intermediaries, EPI aims to rapidly scale Wero from a promising upstart into a genuine challenger to the non-European giants that dominate the market.

The Quest for a United Payments Front

For years, the European Union has pursued the dream of a truly seamless single market, yet payments have remained a stubbornly fragmented frontier. Dominated by American card networks like Visa and Mastercard—which process over €7 trillion in European payments annually—and digital wallets such as Apple Pay and Google Pay, the continent has long sought a homegrown alternative to assert its economic sovereignty.

EPI's Wero is the latest and most significant attempt to realize this vision. Launched in 2024, the digital wallet is built directly on SEPA instant payment rails, enabling direct account-to-account (A2A) transfers. This model bypasses traditional card networks entirely, promising a more efficient and cost-effective system. Since its debut, Wero has shown impressive initial traction, amassing 55 million users across its initial launch markets of Belgium, France, and Germany and processing over 100 million transactions worth more than €7.5 billion in its first year.

The initiative's strategic acquisitions, particularly of the popular Dutch payment scheme iDEAL, signal a clear intent to consolidate, rather than compete with, successful national systems. The plan to migrate iDEAL’s massive user and merchant base to the Wero platform by mid-2027 is a cornerstone of this strategy, aiming to create immediate, large-scale network effects.

Fueling the Engine with Instant Payments

The timing of this push is no accident. The EU’s Instant Payments Regulation (IPR), which took effect in January 2025, mandates that all Eurozone banks must be able to send and receive instant payments. This regulation has effectively laid the groundwork for a service like Wero to thrive, creating a standardized, real-time infrastructure across the continent. ACI's own research forecasts that instant payment transactions in Europe will more than double by 2028, reaching 38.6 billion annually.

This is where ACI Worldwide's role becomes pivotal. As a global leader that already powers 26 instant payment schemes, ACI provides the orchestration layer necessary to make this complex system work seamlessly for merchants and banks. Integrating Wero into its platform simplifies adoption, allowing thousands of businesses to offer the new payment method without undertaking complex, bespoke development projects.

“This collaboration leverages ACI's advanced instant payment processing capabilities to address the fragmentation of payment methods in Europe, providing a unified solution which enables a seamless, secure and efficient payment experience for consumers and merchants,” commented Nick Craig, head of Europe at ACI Worldwide. “Wero will be an important addition to ACI’s best-in-class Payments Orchestration Platform, which has the industry’s widest reach of acquirers and APMs.”

For merchants, the benefits are quantifiable. Wero's A2A model promises significantly lower transaction costs—estimated at around 0.7% of turnover—compared to the 1-3% charged by card schemes or the 2.5-3.5% for wallets like PayPal. Furthermore, with funds settling in under 10 seconds, it provides a dramatic improvement to business liquidity and cash flow.

A Crowded Battlefield: Wero Versus the World

Despite its strong backing and strategic advantages, Wero faces a formidable challenge. The European digital wallet market is a crowded and competitive battlefield. Global tech giants have already established deep-rooted consumer habits, with Apple Pay in particular becoming a dominant force through its seamless integration with its device ecosystem.

Overcoming this inertia is Wero’s primary obstacle. While the lower merchant fees are a compelling proposition for businesses, the incentive for consumers to switch from familiar, convenient options remains a critical question. Some industry analysts are skeptical, arguing that the EU’s 2015 Interchange Fee Regulation (IFR) created such a low-margin environment that the business case for a new network is “fundamentally flawed,” making it difficult to offer compelling economic rewards to all parties.

Furthermore, Wero must navigate the very fragmentation it seeks to solve. Strong national schemes like BLIK in Poland and Bizum in Spain continue to thrive, and even in launch countries, adoption is uneven. Germany, for instance, accounts for only 5% of Wero's transaction volume, indicating a slower uptake. The decision to allow Payconiq in Belgium to coexist with Wero, for now, highlights the delicate balance between pan-European ambition and local market realities.

Nevertheless, the project is gaining momentum. The recent addition of global payment processor Worldpay and European payment service provider Mollie as EPI members signals growing confidence from key industry players. This expanding coalition is crucial for broadening merchant acceptance, a key factor for driving a virtuous cycle of adoption. As EPI’s CEO, Martina Weimert, noted, the ACI partnership is a significant step toward making Wero widely available. “Through the integration onto ACI’s platform, all their merchants and their customers will be able to integrate Wero as a new payment solution, empowering their business and Europe’s resilience at large. Together, we are helping accelerate the development of a more connected, innovative and resilient European payments ecosystem.”
