The European Union (EU) likes to think of itself as a single market, and in many ways it is. The Payment Services Directive (PSD2) has created a common framework for electronic payments, while Strong Customer Authentication (SCA) has standardized how online transactions are verified across the European Economic Area (EEA). For merchants expanding across the EU, this means they can operate within a largely consistent regulatory framework.
However, many merchants discover that the idea of a single payments market starts to unravel as soon as customers hit buy now. A checkout that converts well in Amsterdam may perform less effectively in Bratislava. Customers in Belgium may expect different payment options from those in Germany, while approval rates can vary between markets even when the product, price and customer journey remain unchanged.
These are Europe’s payment borders: the local differences in payment preferences, banking ecosystems and issuer behaviour that continue to influence payment performance within Europe’s shared regulatory framework.
The regulatory foundation in the EEA
PSD2 established a common regulatory framework and introduced shared standards around security, consumer protection, and access to payment accounts. For merchants expanding across the region, that means they don’t need to navigate a completely different regulatory environment every time they enter a new market.
One of the most significant changes introduced was Strong Customer Authentication (SCA), which requires many customer-initiated electronic payments to be authenticated using at least two independent elements.
The way SCA is applied depends on the payment method. For card payments, authentication is often handled through 3D Secure 2 (3DS2), which allows the customer’s bank (the issuer) to assess transaction risk and either authenticate the payment without customer action or request an additional verification step.

Other payment methods may use different authentication methods. For example, account-to-account payments may involve customers confirming a payment through their banking environment, while digital wallets such as Apple Pay and Google Pay typically combine possession of a registered device with another authentication factor, such as biometric verification through a fingerprint or facial recognition.
However, every authentication request introduces a trade-off between security and customer experience. Challenge customers too often and checkout abandonment can increase; fail to apply SCA where required and transactions may be declined or fall outside regulatory requirements.
This is where the distinction between regulation and payment borders becomes important. Merchants may operate within one regulatory framework, yet they still need to navigate different payment habits, banking ecosystems, and issuer behavior in each market they enter. More information on the accepting card payments in the EU can be found here.
Payment borders begin with customer expectations
Payment preferences are often shaped by local banking ecosystems, consumer habits, and trust. Belgian consumers have long embraced Bancontact, a familiar account-to-account payment method connected to their domestic banking environment. In Poland, BLIK has become a widely used payment option, while PayPal has a strong foothold among German consumers.
These differences exist because payments are personal, they are based on a customer’s relationship with their bank, preferred payment brands, and the services they use every day. A payment method that feels familiar in one market may feel unfamiliar or inconvenient in another.
Supporting local preferences without adding complexity
For merchants expanding across Europe, supporting these preferences shouldn’t mean building a separate payment infrastructure for every country. Modern payment providers increasingly offer access to multiple local and alternative payment methods through a single API, allowing businesses to adapt their checkout experience as they enter new markets.
Open banking: reducing borders but not removing them
Open banking represents the next stage in this evolution. By enabling customers to authorize payments directly from their bank accounts, open banking has the potential to create more consistent account-to-account payment experiences across Europe and build on the trust customers already have with their banks.
However, the reality remains fragmented. Connecting to banks across Europe is still challenging, with differences in API implementation, technical capabilities, and user experiences between financial institutions. PSD2 created the regulatory foundation for open banking, but the underlying infrastructure and adoption levels are not yet identical across markets.
For merchants, this means open banking represents significant potential for the future, but local payment knowledge remains essential. The technology may help reduce some payment borders over time, but today’s eCommerce landscape still requires an understanding of how customers prefer to pay in each market.
Payment borders continue behind the scenes
Payment borders don’t disappear when a customer clicks “Pay.” Behind the checkout, transactions still move through payment networks, banks, and providers that operate within different market environments. Local banking relationships, issuer behavior, and payment infrastructure can all influence whether a transaction is successfully completed.
Card payments provide one clear example. An important and often overlooked measure of card payment performance is the authorization rate: the percentage of payment attempts approved by the customer’s card issuer. Merchants often focus on checkout conversion, but declined transactions after checkout represent revenue that may be recovered through optimization.
Acquiring can play an important role in this process. When payments are processed through acquiring relationships that align with a merchant’s target markets, transactions may be better positioned for approval by local issuers. The issuing bank always makes the final decision, but factors such as transaction routing, acquiring setup, and payment provider relationships can influence avoidable declines.
Even a one or two percent improvement in authorization rates can represent significant recovered revenue for high-volume merchants because it converts transactions that would otherwise be declined after customers have already committed to purchase.
Authentication strategy also matters. For card payments, applying 3DS2 intelligently, using exemptions where permitted, and avoiding unnecessary authentication challenges helps merchants meet PSD2 requirements while reducing friction for legitimate customers.
Choosing a payment partner that understands Europe
In broader terms payment performance depends on more than accepting a payment method. Merchants need to understand how payments are processed, authenticated, and approved within each market they serve.
When choosing a payment partner merchants should understand how they support local payment methods, approach acquiring across different European markets, manage SCA and 3DS2, and help optimize authorization rates over time.
It’s also important to know what happens when something doesn’t work. Large enterprises often have dedicated payments specialists, while growing merchants are left to interpret dashboards and documentation on their own. Practical guidance can be just as valuable as payment technology itself.
Supporting merchants across Europe’s payment borders
Europe’s payment landscape has become more consistent from a regulatory perspective, but local differences remain. The businesses that optimize for these payment borders are often the ones that convert more customers and recover more revenue as they expand across Europe.
DIMOCO helps merchants navigate these payment borders through offering the full payment stack, including European card acquiring, access to local payment methods, and dedicated account management. As an Austrian Financial Market Authority (FMA)-licensed payment institution, DIMOCO supports businesses looking to optimise payment performance as they expand across European markets.
