The future of payments: How GenAI and modernization are reshaping the industry
Looking at the trends around us, it’s clear that the payments industry has witnessed a rapid jump in the adoption of modernization strategies, such as the use of generative and agentic AI, cloud-native architectures, and modular payment systems in recent years. This pattern of growing willingness to quickly move from legacy payment systems, which are often associated with high operating costs, outdated technology and software, lack of newer functionality, as well as risks around security and data, has already signaled a revolution in the financial technology sector.
Accenture's latest Technology Reinvention Study revealed that ‘leading banks are already investing significantly in AI and generative AI, and have managed to automate 40% of manual tasks in their payments business’.1
This increasing reliance on AI technologies has resulted in growing pressure for today’s banks and fintechs to modernize their payment systems for the future. Strengthening cybersecurity and fraud detection, increasing cost efficiencies, and enhancing a personalized customer experience are just a few of the benefits shaping modern payment systems.
What modernization means for the future of payments
Payments modernization is about transforming legacy payment infrastructures into cloud-native, API-first platforms that empower banks to move faster, innovate confidently and deliver connected customer experiences. By moving away from rigid, monolithic systems, financial institutions (FIs) gain the flexibility to process payments in real-time, scale effortlessly, and collaborate seamlessly across ecosystems.
Cloud technology and open APIs unlock new possibilities for integration and innovation, enabling banks to bring new products to market faster, adapt to changes quickly, and maintain resilience at every level. In fact, cross-border spending continues to grow: from $194.6 trillion in 2024 to a projected $320 trillion by 2032 - a clear signal that integrating cloud technologies and open APIs is a future-ready payments landscape where institutions can drive growth, efficiency and customer trust.
The business case for modernizing payment systems
FIs are modernizing their payment systems in response to growing transaction volumes, rising demand for real-time payments, and intensifying competitive pressures. A BCG study cites that, ‘Agentic AI is set to influence over $1 trillion in e-commerce spending […] 81% of US consumers expect to use agentic AI tools to shop, which will shape more than half of all online purchases in the near future.’
Banks now face increasingly complex payment channels, including cross-border, multi-currency, and other digital options, resulting in legacy systems, such as ACH payment networks, struggling to meet new operational demands, such as Same Day ACH systems in the US.
The shift to real-time payments adds further challenges. Core processing systems designed for batch operations can experience processing delays, operational strain, and downstream friction due to regulatory compliance and slow adoption of new payment schemes, while value-added services such as fraud detection, risk monitoring, and compliance checks must also operate at real-time speeds or risk failing to protect customers effectively.
Delaying payment innovation increases costs, reduces system resilience, and puts banks at risk of falling behind competitors who can deliver faster, more flexible, and customer-centric payment solutions.
Practical approaches to modernizing payments
FIs can modernize their payment systems in a structured, risk-managed way by adopting a layered approach that allows new capabilities to be introduced without disrupting day-to-day business operations. By deploying modern, cloud platforms built on microservices, APIs, containerization, and CI/CD methodologies, banks can update their payment capabilities gradually and safely.
Payment hub architecture enables FIs to bring new payment rails online at their own pace and budget, running modern services alongside existing systems until they are ready to transition fully. This is particularly important as cash usage continues to decline globally, now accounting for 46% of payments, down from 50% in 2023.2
By leveraging open-source tools, modular components, and a composable banking model, organizations can tailor solutions to their needs while accelerating payments innovation and unlocking the capabilities of Artificial Intelligence (AI) in banking.
The adoption of global data and messaging standards, such as ISO 20022, further enhances data quality, interoperability, and operational efficiency. This incremental, yet future-ready approach allows banks to modernize with confidence, reducing risk, controlling costs, and unlocking long-term agility and scalability.
Balancing payments modernization with other banking priorities
Without a modern infrastructure, the potential for enhancing customer experiences, improving operational efficiency, and launching new products is limited for FIs. Leveraging AI and advanced data analytics further amplifies these benefits, enabling smarter and faster decision-making across the payment lifecycle, from proactive fraud detection to optimized liquidity management and cash flow.
In this context, modernization is not just an IT upgrade, but a strategic enabler. Essentially, modernization lays the foundation for banks to perform all other tasks more effectively and efficiently, thereby turning operational excellence into a driver of customer trust, loyalty, and long-term growth. Data from J.P. Morgan indicates that 55% of organizations are currently adopting AI for productivity. Thanks to AI advancements, banks and their fintech partners can make payments more instant, secure and transparent.
