The Platform Layer in Payment Infrastructure

Why app stores, checkout rules and mobile access are becoming part of the payments competition debate

Payment infrastructure is often discussed through banks, card networks, payment service providers and settlement rails.

But another layer is becoming increasingly important: platforms.

On 30 June 2026, the UK Competition and Markets Authority proposed changes that could allow app developers to direct users to alternative payment options outside Apple and Google app stores. The regulator is also considering whether Apple should open access to its near-field communication technology, which is used for contactless payments.

This is more than an app-store policy debate.

It is a payment infrastructure debate.

It shows how payment access, checkout choice and competition can be shaped by the platforms that control digital distribution.

Payments are not only rails

A payment rail can be fast, efficient and reliable.

But if businesses cannot easily access it, present it to customers or route users toward it, its practical value becomes limited.

That is why platform rules matter.

In mobile ecosystems, the app store is not only a software distribution channel. It can also influence how payments are offered, which payment methods are visible, what fees apply, how customers are redirected and which providers can compete inside the user journey.

For developers, merchants and fintech companies, this can directly affect margins, product design and customer experience.

For the wider market, it can affect payment innovation.

Steering is becoming a payment issue

The concept of “steering” is simple.

Can a business tell a customer that another payment option is available?

Can it direct the customer to a lower-cost checkout?

Can it show different payment flows depending on price, geography, risk or customer preference?

These questions are familiar in merchant payments, but they are now becoming central to app-store economics as well.

If businesses are restricted from directing users to alternative payment options, payment choice becomes less open. If steering is allowed, businesses may gain more flexibility to manage cost, improve checkout design and test alternative payment models.

The challenge is to balance competition with user protection.

Customers should not be pushed into unsafe or confusing payment journeys. But platforms should also not be able to use security concerns as a blanket argument against all competition.

The future of payment access will likely depend on finding that balance.

NFC access and the mobile payments stack

The NFC question is equally important.

Contactless payments depend on hardware, software, device permissions, wallet integration and security controls. If access to that layer is limited, then competition in mobile payments can also be limited.

Opening access could allow more payment providers to build wallet-like or contactless payment experiences inside mobile devices.

That could support account-to-account payments, bank-led payment solutions, merchant apps, loyalty-linked payments, digital credentials and other new payment experiences.

But this also introduces risk.

Payment infrastructure on mobile devices needs strong authentication, fraud prevention, privacy protection, user consent, dispute handling and operational resilience.

The question is not simply whether NFC access should be open.

The question is how open access can be governed safely.

The fee question

App-store payment rules are also about economics.

If businesses can use alternative payment methods, the cost structure changes. But if platforms replace existing commissions with new “access” or “steering” fees that are too high, the practical benefit may be limited.

This is why fee design matters.

A fair payment infrastructure model needs to recognise that platforms provide value: distribution, security, discovery, app review and user trust.

But it also needs to ensure that fees are connected to real cost and value, rather than simply preserving old economics under a different name.

For merchants and developers, the issue is not only the absolute fee.

It is whether the payment model gives them enough flexibility to manage margins, customer experience and innovation.

Why businesses should pay attention

This may sound like a large-platform regulatory issue, but it matters for any business that depends on digital checkout.

Payment choice affects conversion, pricing, refunds, fraud exposure, reconciliation and customer support.

If alternative payment options become easier to offer inside mobile ecosystems, businesses may gain more control over their payment strategy.

They may be able to test lower-cost rails, improve account-to-account flows, build stronger loyalty experiences, or reduce dependence on a single payment model.

But greater choice also creates operational complexity.

Businesses will need to think about checkout design, customer communication, fraud controls, payment data, reconciliation and dispute handling across more payment flows.

More payment options only create value if they are well integrated.

The broader market signal

The platform layer is becoming part of payment infrastructure.

That is the main signal.

Historically, payment competition was often shaped by banks, schemes, processors and regulators. Increasingly, it is also shaped by mobile operating systems, app stores, wallets and digital platforms that control access to customers.

This means the future of payments will not be determined only by which rail is fastest or cheapest.

It will also be determined by which payment methods can reach users, which interfaces are allowed, which fees apply, and how much control businesses have over the checkout journey.

Payment infrastructure is becoming more connected to digital market regulation.

MetaNord’s view

At MetaNord, we see this as part of a wider shift in payment infrastructure.

The industry is moving from isolated payment rails toward broader operating environments where access, data, user experience, regulation and control all matter.

A payment method does not succeed only because it exists.

It succeeds when businesses can offer it, customers can understand it, risks can be controlled and finance teams can reconcile it.

The platform layer is now part of that equation.

For payment infrastructure to become genuinely competitive, businesses need more than rails.

They need access, optionality and operational control.
