As Europe pushes for greater control over its payments infrastructure, interoperability has become a central theme. The ability to move money seamlessly across borders, banks and systems is no longer a future ambition – it is a strategic necessity. Two of the most discussed developments in today’s payments space are Wero and Pay by Bank. While they are often mentioned in the same context, they are at very different stages of maturity when it comes to interoperability.
A shared goal: European interoperability
Europe has set itself the goal to develop a more unified and sovereign payments ecosystem. Today, many European countries still rely on local payment methods – each with their own standards, user experiences and technical integrations.
Across the continent, this has resulted in a landscape of strong national champions, including:
- Bizum (Spain)
- BLIK (Poland)
- Swish (Sweden)
- MobilePay (Denmark/Finland)
- Vipps (Norway)
- Bancomat Pay (Italy)
- Wero (Germany, France, Benelux)
Each of these works effectively within its own market. Together, they form a fragmented European landscape.
This is exactly what Europe aims to address.
The direction is clear:
- more European control
- more standardization
- less fragmentation
At a strategic level, both Wero and Pay by Bank contribute to this ambition. However, the two systems support the required interoperability in significantly different ways.
Wero: building towards interoperability
As an initiative under the European Payments Initiative (EPI), Wero is aimed at creating a unified European payment solution that can replace the fragmented national schemes with a single, interoperable system.
This is a strategic and long-term vision that requires:
- alignment between banks across multiple countries
- harmonization of standards and processes
- gradual rollout across markets
In practice, this means Wero operates within the existing landscape of national payment methods.
Its challenge is twofold:
- integrate existing national champions
- or replace them over time
Both paths require coordination across markets, banks and systems.
In other words, interoperability is the goal, but the infrastructure is still being built and adopted.
Pay by Bank: interoperability is already in place
Pay by Bank takes a different approach. Rather than building a new scheme, it leverages infrastructure that already exists in Europe:
- bank accounts
- open banking frameworks (PSD2)
- real-time payment rails
Because these foundations are already in place across Europe, Pay by Bank is inherently interoperable. Payments can be initiated directly between accounts, across borders, without the need for a new, overarching scheme to be implemented first. Rather than being a future ambition, interoperability is already an operational model.
What this means in practice
This difference in approach has direct implications for organizations.
With Wero:
- interoperability depends on rollout and adoption
- integration with multiple markets takes time
- the ecosystem evolves gradually
With Pay by Bank:
- pan-European reach is available today
- a single integration connects multiple markets
- scaling does not depend on local schemes
This is not just a technical distinction.
It is the difference between building interoperability and already having it.
From vision to execution
As the European payments ecosystem evolves, the key question is no longer how interoperability for digital sovereignty should look, but how quickly it can be realized in practice. After all, for merchants and platforms, availability matters more than ambition.
Waiting for a new scheme to reach scale introduces uncertainty:
- uncertain timelines
- fragmented rollout across markets
- dependency on adoption by multiple stakeholders
Digital sovereignty is not only about building the future. It is about using what already works. Pay by Bank avoids complexity by building on what already exists. It enables organizations to operate across Europe today, with a single integration and a consistent user experience.
This is where vision and strategy meet execution.
Looking ahead
In the coming years, initiatives like Wero will continue to evolve, and may contribute to further standardization in the European payments landscape.
At the same time, Pay by Bank is already setting the benchmark for what interoperable, European-first payments look like in practice.
The real distinction lies in timing. Organizations that act today can already benefit from a model that:
- is built on European infrastructure
- operates across borders
- scales without waiting for future adoption cycles
Curious how Pay by Bank can help your organization scale across Europe, without the complexity of multiple local integrations?
At IBANXS, we provide a single connection to European bank rails, enabling real-time, compliant and interoperable payments across markets.
