How is the shift from payments as a standalone product to embedded infrastructure reshaping competitive dynamics between merchants, banks, and fintech providers?

“The shift from payments as a standalone product to embedded infrastructure is redistributing control across the payments ecosystem. Payments are no longer a discrete service that merchants consume, but an embedded capability they orchestrate, which is moving the competitive focus away from transaction processing and towards ownership of the customer relationship and the broader digital experience.

“It’s important to stress that banks and fintechs are still essential – it’s just that their roles are evolving and they are becoming infrastructure enablers. Plug and play ecosystems, such as the Tag Systems CaaS (Card as a Service) platform, where services can be integrated through a single interface rather than stitched together across multiple vendors, mean that merchants can assemble their own fintech stacks using modular capabilities such as issuing, processing and analytics delivered through a unified platform.”

What strategic advantages do merchants gain by owning more of the payments stack, and where do the risks begin to outweigh the rewards?

“Owning more of the payments stack enables merchants to differentiate the customer experience and embed financial services, such as wallets or credit, directly into the customer journey. With richer data insights, embedded finance and product expansion also enable merchants to identify growth opportunities and opportunities to build customer value.

“The risky part is operational complexity. Where complexity increases beyond what the organisation can manage effectively, such as fraud prevention, compliance, reconciliation, customer support, etc. The benefits of building those customer relationships can quickly turn sour.

“With conventional models, there is also the danger of vendor fragmentation, which can slow innovation and increase costs. That’s why Tag Systems has developed a simplified model based on a single primary provider and unified infrastructure, which reduces operational overheads and enables greater flexibility, including the ability to switch vendors without major disruption.”

In what ways does merchant-controlled payment infrastructure change the role of customer data in driving growth, loyalty, and personalisation?

“Merchant-controlled infrastructure transforms data into a central driver of strategy rather than a secondary output of transactions. Merchant-controlled infrastructure provides real-time visibility into customer behaviour, enabling more precise segmentation and engagement.

“With embedded AI and machine learning, merchants can move towards behavioural modelling and hyper-personalised recommendations that directly influence customer outcomes. This creates a continuous feedback loop in which payment data informs product design, marketing, and financial services integration. The challenge is ensuring that this data is governed responsibly – trust is not just about governance; it can become a critical and valuable differentiator.”

How should traditional payment providers evolve their value propositions to remain relevant in a world of merchant-owned fintech ecosystems?

“Traditional payment providers have an opportunity to reposition themselves as infrastructure partners rather than product owners. This means delivering modular, API-driven platforms that allow merchants to build and scale their own financial ecosystems.

“Flexibility is key. Providers must support seamless integration across issuing, processing and analytics through standardised interfaces, while also enabling rapid deployment of new capabilities. Performance and resilience are equally important, with infrastructure designed for high-volume authorisation and automatic scaling. It’s vital to embed security at every level too, with encryption and authentication standards that meet or exceed regulatory expectations.”

What operational and technological capabilities must merchants develop to successfully internalise payments without compromising scalability or security?

“Merchants need strong integration capabilities, particularly through APIs that connect card issuance, processing, payments and analytics into a single environment. They also need to manage real-time data flows and ensure high levels of security and authentication that maintain robust protection against fraud.

“CaaS has become a critical enabler in this space. Platforms that integrate onboarding, KYC and AML, fraud prevention, issuing, tokenisation and payment processing into a unified system, allow merchants to launch and scale programmes in weeks rather than months, supported by cloud-native infrastructure that enables automatic performance scaling. Meanwhile, the ability to orchestrate multiple capabilities through a single platform with full automation reduces back-office complexity and cost.”

How might regulation respond to the blurring lines between merchants and financial institutions, and what unintended consequences could arise?

“Regulation is likely to expand as merchants take on more financial functionality. Areas such as consumer protection, data usage and operational resilience will come under greater scrutiny, even where services are delivered in partnership with regulated entities.

“It may be that increased compliance requirements favour larger organisations with the resources to manage them, which could potentially limit competition. Whether regulation can keep pace with innovation is another big question as modular, multi-partner ecosystems become more complex and the emergence of biometric payments takes hold.”

To what extent will merchant-owned fintech accelerate the fragmentation or consolidation of the broader payments landscape?

“The likelihood is that it will drive both at the same time. On the front end, there will be greater fragmentation as merchants build tailored financial ecosystems for their customers. Each will reflect different use cases, from closed-loop wallets to embedded credit. At the infrastructure level, however, we’re likely to see consolidation with a smaller number of providers offering integrated capabilities underpinning a wide range of programmes.”

What does success look like for merchants five years from now if payments truly become invisible infrastructure rather than a customer-facing product?

“In my view, success will be defined by how seamlessly financial services are embedded into the customer journey. Payments will no longer be a visible step; instead, they will be an always-on capability that supports engagement and value creation.

“Merchants that can combine real-time data, AI-driven insights and integrated financial services into a cohesive experience are the most likely to succeed. Payment infrastructure that enables rapid deployment and ongoing optimisation will be critical in enabling them to scale quickly, adapt services and maintain consistent performance.

“The rise of merchant-owned fintech is not about replacing banks or bypassing regulation. It is about reconfiguring the ecosystem so that merchants can take greater control of customer experiences while relying on infrastructure partners to handle complexity. By bringing together issuing, processing, analytics and programme management into a single, modular platform, CaaS allows merchants to innovate more quickly and scale more effectively.”
