QR + Identity + Interoperability: The New African Payments Stack

Why the next generation of African payments will be built around universal payment interfaces, trusted digital identity and infrastructure that connects multiple financial networks

Introduction: Payments Are Becoming a Connected Stack

Africa’s digital payments ecosystem has spent the past decade expanding.

More consumers have gained access to mobile money, digital wallets, bank transfers and card payments. Instant payment systems are expanding, while fintech companies have made it easier for merchants to accept digital payments.

The next challenge is different.

Africa does not simply need more ways to pay. It needs existing payment systems to work together.

That is pushing payment architecture toward a new model built around three increasingly connected components:

QR and other universal payment interfaces → Digital identity → Interoperable payment infrastructure

South Africa’s developing QR+ and payment-credential initiatives provide one concrete example. At the continental level, the World Bank is similarly emphasizing interoperability between fast payments, digital identity and trusted data exchange as a foundation for modern digital economies.

Together, these developments point toward a future where customers do not need to understand which payment network sits behind a transaction.

They simply need a trusted way to identify themselves and initiate a payment.

The infrastructure handles everything else.

QR Is Evolving Beyond a Payment Method

QR payments are not new.

Their role in payment infrastructure, however, is changing.

In fragmented environments, individual payment providers can operate their own QR systems. A merchant may consequently need several QR codes to accept payments from customers using different applications.

That creates exactly the fragmentation digital payments are supposed to eliminate.

South Africa is now addressing this problem through its QR+ Standard, introduced under the South African Reserve Bank’s Payments Ecosystem Modernisation Programme.

Rather than creating another proprietary QR payment network, QR+ is intended to provide an interoperable payment-initiation interface across different PSPs, payment rails and stores of value.

That distinction is critical.

The QR code does not need to become the payment rail.

It can become the interface to multiple payment rails.

One Interface, Multiple Payment Networks

Consider what happens in a traditional closed QR ecosystem.

A customer opens Provider A’s application.

The merchant displays Provider A’s QR code.

The transaction stays inside Provider A’s network.

That works until the customer uses Provider B.

Interoperability changes the model.

The merchant can present a standardized payment interface while infrastructure underneath determines how the transaction should be processed.

Conceptually, the architecture becomes:

Customer → QR / Digital Link → PSP → Payment Rail → Settlement

The customer interacts with a simple interface.

Behind it, several different financial systems may be available.

South Africa’s QR+ version 1.2 illustrates this approach. Published in July 2026, the update added support for integration with the PayShap payment rail. SARB explicitly notes that QR+ does not execute the payment itself; it passes standardized payment-initiation information to the selected rail, which processes the transaction. (Ресбанк)

That separation between payment initiation and payment execution could become an important principle of future African payment architecture.

QR Is Only the Front Door

A QR code alone does not solve payment fragmentation.

Behind the interface, payment infrastructure still needs to determine:

• who is paying
• who is receiving
• which account or wallet is involved
• which payment rail should be used
• whether the transaction is authorized
• whether additional authentication is required
• whether fraud indicators are present
• where settlement should occur

This is why payment interfaces increasingly need to connect with another infrastructure layer:

digital identity.

Identity Is Becoming Part of the Payment Stack

Historically, identity verification has often occurred separately from payments.

A customer completes KYC when opening an account or wallet. A merchant completes KYB during onboarding. Once verified, the payment system largely relies on credentials associated with that particular provider.

More interoperable ecosystems create a different challenge.

If customers move between providers and payment rails, trust needs to move with them.

Digital credentials offer one possible solution.

Instead of every provider repeatedly establishing identity from scratch, verified information could—subject to consent, regulation and security controls—be represented through reusable credentials.

The World Bank has described digital identity, fast payments and trusted data exchange as complementary components of digital public infrastructure. Its recent work on connecting digital ID with fast payments explores reusable payment identity credentials that could support onboarding, authentication, payee confirmation and authorization across providers. (World Bank)

The broader idea is straightforward:

identity becomes portable infrastructure rather than an isolated onboarding event.

South Africa Is Already Connecting Identity and Payments

South Africa’s modernization programme provides another practical example.

Alongside QR+, the SARB is developing PEMKey, a Payment Credential Ecosystem intended to support secure, reusable and trusted digital credentials across the payment ecosystem.

The goal is to allow people and organizations to share verifiable information securely, supporting trusted participation while helping address fraud and financial inclusion. (Ресбанк)

Importantly, the initiatives are not developing entirely independently.

SARB’s 2026 modernization roadmap includes PEMKey in customer onboarding and envisages using it for payer and payee verification alongside direct participation and PayShap development. (Ресбанк)

That begins to reveal what the next payment stack could look like.

The interface initiates the transaction.

Identity establishes trust.

Interoperable infrastructure moves the money.

Interoperability Is the Layer That Makes Everything Work

QR and digital identity become considerably more valuable when the systems underneath them are interoperable.

Interoperability allows different:

• banks
• PSPs
• wallets
• payment rails
• merchants
• financial platforms

to participate in a connected ecosystem.

Without it, digital finance risks becoming a collection of sophisticated but isolated networks.

A customer may have money in Wallet A.

A merchant accepts Wallet B.

A business operates through Bank C.

Another provider processes its international payments.

Every individual service works, but the ecosystem remains fragmented.

Interoperability attempts to remove those boundaries.

Africa Is Moving Toward More Instant Payment Infrastructure

This matters because the underlying payment rails themselves are changing.

A 2026 World Bank white paper on scaling instant payments in Africa reported that 25 African countries had live domestic instant payment systems in 2025, up from 20 when the landscape was assessed in 2022. Development was also underway in another 19 countries. (fastpayments.worldbank.org)

The opportunity is therefore increasingly about what can be built on top of those rails.

QR interfaces can make them easier to access.

Identity can make participation more trusted.

APIs can make them easier for fintechs to integrate.

PSPs can make them usable for merchants.

Orchestration can connect several rails simultaneously.

This creates a payment ecosystem rather than simply a payment system.

The Merchant Experience Could Become Much Simpler

Payment complexity is particularly visible at the merchant level.

A merchant may currently need different arrangements for:

• cards
• mobile money
• bank transfers
• QR payments
• wallets

Each may involve separate integrations, reporting and reconciliation.

Interoperable infrastructure can abstract much of that complexity.

The merchant sees one payment acceptance environment.

The infrastructure underneath determines how the customer wants to pay and where the transaction should be processed.

This can create a much simpler merchant experience without requiring the underlying financial ecosystem itself to become uniform.

That is an important distinction.

Interoperability does not require every payment method to become identical.

It requires them to communicate.

PSPs Become Connectivity Layers

This transition changes the role of payment service providers.

Historically, a PSP’s primary value might have been providing access to payment acceptance.

In an interoperable environment, the PSP increasingly coordinates multiple components of the transaction.

The PSP can connect:

Merchant → Identity → Payment Method → Payment Rail → Settlement

Instead of simply processing transactions, PSPs become abstraction layers over financial complexity.

Their value increasingly comes from simplifying an ecosystem containing multiple rails, providers and financial services.

Payment Orchestration Becomes Essential

More interoperability creates more choice.

More choice creates a need for orchestration.

Imagine a merchant capable of processing a transaction through three different providers.

Which one should be used?

The answer could depend on:

• availability
• transaction type
• geography
• cost
• historical success rates
• settlement speed
• risk

Payment orchestration provides the layer that manages those choices.

Instead of hard-coding every transaction route, businesses can operate through infrastructure capable of selecting between different providers and rails.

The emerging stack therefore becomes richer:

Interface → Identity → Orchestration → Payment Rail → Settlement

AI Will Add Intelligence to the Stack

Once payment infrastructure becomes connected, AI can begin optimizing it.

An intelligent orchestration system could evaluate payment conditions in real time and determine which available route is most appropriate.

AI could also analyze identity and behavioral signals to support fraud detection.

The system might consider:

• device behavior
• transaction history
• merchant patterns
• identity credentials
• payment method
• provider performance
• fraud indicators

This turns interoperability into more than connectivity.

It creates the foundation for intelligent payments.

AI cannot create payment options that do not exist.

But once multiple rails are connected through common infrastructure, AI can help determine how those options should be used.

Identity Could Strengthen Fraud Prevention

Fast payments create a particular security challenge.

The faster money moves, the less time providers have to detect suspicious activity before funds become available to the recipient.

Identity infrastructure can provide additional context.

Instead of evaluating only:

Where is this payment going?

a payment system can increasingly evaluate:

Who is sending it?

Who is receiving it?

Are those identities verified?

Does the transaction match expected behavior?

The World Bank has specifically identified integration between digital identity and fast payments as an opportunity to improve onboarding, authentication and fraud prevention. (World Bank)

Identity therefore becomes not merely a compliance function but part of real-time payment security.

QR Can Become a Universal Payment Interface

The long-term potential of QR goes beyond replacing cash at physical merchants.

QR codes and digital links can act as standardized mechanisms for initiating transactions across many environments.

Potential use cases include:

• retail checkout
• e-commerce
• invoices
• person-to-person payments
• merchant-to-merchant payments
• bill payments
• transportation
• government services

The important element is not the QR image itself.

It is the standardized payment information behind it.

South Africa’s QR+ already reflects this broader concept: the standard covers QR codes, barcodes and digital links rather than treating QR as the only possible interface. (Ресбанк)

The interface can change.

The interoperable infrastructure underneath remains.

Cross-Border Interoperability Is the Bigger Opportunity

Domestic interoperability is only the first step.

Africa’s larger challenge is connecting payment ecosystems across borders.

National payment systems have historically developed independently.

That creates friction for:

• regional merchants
• marketplaces
• exporters
• digital businesses
• SMEs
• international platforms

The World Bank’s 2026 work on African integration identifies interoperable payment and digital systems as part of the infrastructure required to make African markets function more effectively together. (Світовий Банк)

If domestic instant payment systems become increasingly interoperable regionally, the architecture could eventually support transactions where customers continue using familiar local payment experiences while infrastructure connects those payments across borders.

That would represent a significant step toward truly pan-African payment infrastructure.

Local Payments Do Not Need to Disappear

The emerging architecture does not require Africa to adopt one universal payment method.

That is unlikely to be necessary.

Different markets can continue using:

• bank accounts
• mobile money
• wallets
• cards
• instant payments

The important change is what happens between those systems.

Interoperability allows local financial ecosystems to remain locally relevant while becoming part of broader networks.

This could prove more practical than trying to replace successful domestic payment systems with a single continental payment method.

APIs Hold the Stack Together

APIs are what allow these layers to communicate.

Modern payment infrastructure increasingly needs APIs connecting:

• payment initiation
• identity
• transaction processing
• fraud monitoring
• settlement
• reconciliation

A standardized API layer makes it easier for fintech companies to build on top of existing infrastructure.

Instead of creating every financial capability internally, companies can assemble products using specialized services.

This makes the payment ecosystem more modular.

And modular infrastructure is easier to expand.

What This Means for African Payment Platforms

The competitive landscape for African PSPs is consequently changing.

Providing access to one payment rail will become less valuable as infrastructure becomes increasingly interoperable.

The opportunity shifts toward managing the connections between systems.

Next-generation platforms will increasingly need capabilities around:

• multi-provider connectivity
• payment orchestration
• identity integration
• real-time transaction monitoring
• fraud intelligence
• reconciliation
• API infrastructure
• cross-border connectivity

The strongest platforms may not own every payment rail.

They will make multiple rails work together.

How Unipesa Fits Into the New Payments Stack

Unipesa, a portfolio company of Velex Investments, is focused on building scalable fintech infrastructure for businesses operating across African markets.

Its technology supports payment orchestration, API-first integrations, POS infrastructure, digital wallets, lending solutions, communication services and international payment capabilities.

This infrastructure-first approach aligns closely with the emerging payments stack.

As payment initiation becomes more standardized and financial networks become increasingly interoperable, businesses need an infrastructure layer capable of connecting different providers, services and payment environments.

Unipesa’s role is therefore not about creating another isolated payment method.

It is about providing infrastructure that helps businesses operate across a financial ecosystem containing many of them.

The strategic value lies in the connection layer.

Conclusion

The next phase of African payments will not be defined by QR codes alone.

Nor will it be defined solely by digital identity or instant payment systems.

The transformation happens when these capabilities begin working together.

QR and digital interfaces simplify payment initiation.

Digital identity establishes trust.

Interoperability connects financial networks.

Orchestration manages the complexity.

AI adds intelligence.

Together, they form a new payment architecture capable of supporting a more connected African digital economy.

The future payment experience may look remarkably simple to the customer: scan, authenticate, pay.

But underneath that interaction will sit an increasingly sophisticated infrastructure stack connecting identity, providers, payment rails and settlement systems.

The future of African payments is not another closed network. It is a stack designed to make different networks work together.
