ACI Worldwide Integrates Wero as a New Payment Option for European Merchants

ACI Worldwide, a global provider of real‑time payment solutions, announced the integration of Wero, a new payment option designed for European merchants, marking a significant step in the company’s strategy to broaden its portfolio of locally relevant services.

How Wero fits into the European payments landscape

Wero is positioned as a digital wallet that leverages the European Payments Initiative (EPI) framework, which aims to create a unified, pan‑European payment instrument. By building on EPI’s open‑access standards, Wero offers a seamless checkout experience that can be embedded in online stores, point‑of‑sale terminals, and mobile applications without requiring merchants to manage multiple national schemes.

The partnership with ACI Worldwide gives Wero access to the firm’s extensive processing network, fraud‑prevention tools, and real‑time settlement capabilities. ACI’s existing relationships with banks and payment service providers across the continent mean that the Wero solution can be rolled out through established channels, reducing the time needed for merchants to adopt the new option. In practice, the integration allows a merchant’s existing ACI gateway to present Wero alongside traditional card schemes, direct debits, and emerging fintech solutions.

Implications for merchants and consumers

For merchants, the addition of Wero expands the range of payment methods available at checkout, which can improve conversion rates by catering to shoppers who prefer a single, unified European wallet. The solution also promises lower transaction costs compared with some cross‑border card schemes, because it bypasses the need for multiple currency conversions and intermediary fees. Retailers that already use Cardentity for card‑based processing may find the transition to include Wero straightforward, given the shared infrastructure.

Consumers benefit from a consistent user experience across borders, as Wero stores payment credentials and preferences in a secure, tokenised format that complies with EU data‑protection regulations. The wallet supports instant payments, meaning that purchases are settled in near real‑time, which can be especially valuable for time‑sensitive e‑commerce transactions. Users who need to move funds between accounts can still rely on services such as Wise for cross‑border transfers, ensuring that the broader ecosystem remains flexible.

Looking ahead, ACI Worldwide’s integration of Wero signals a broader industry shift toward regionally unified payment solutions. As more merchants adopt the wallet, network effects are likely to encourage additional banks and fintech firms to join the EPI ecosystem, further strengthening the alternative to legacy card networks. The rollout is expected to continue throughout Europe, with early adopters providing feedback that will shape future enhancements, such as expanded loyalty programmes and deeper integration with emerging digital‑identity frameworks.
