What is payments modernization?

While there is no singular definition for payments modernization, it broadly refers to the strategic overhaul of traditional payments infrastructure within financial institutions. Payments modernization requires banks to adopt modern technologies that align with global standards to optimize the speed and security of transactions, enhance the overall user experience, and meet the demands of today’s digital economy.

Payments modernization involves upgrading or replacing legacy systems with a new architecture that drives a more efficient 24/7, real-time payment. Through modernization, financial institutions can create a unified payments platform across account-to-account payments (A2A), card, and digital use cases that simplify processes, deliver multi-provider flexibility, and orchestrate payments globally for better customer experiences.

What are the key drivers behind payments modernization?

Several factors contribute to the need for financial institutions to adopt modern payment systems including:

Data insights

Modern payment solutions enable financial institutions to unlock the data within payments by facilitating real-time data capture and analysis. Modern solutions are designed to handle large volumes of transactions quickly and accurately, providing a wealth of structured data that banks can use to access deeper insights. These solutions also come with integrated data analytics tools that enable institutions to track and analyze transaction patterns, customer behaviors, and market trends, allowing for more informed decision-making and improved service.  

Technological advancements

Most legacy payment systems are incompatible with newer technologies, such as real-time payments, cloud computing, software as a service (SaaS), blockchain, AI, and machine learning (ML) — technologies essential to accessing granular data insights. For example:

  • ML algorithms identify patterns and anomalies within transaction data, helping to detect fraud and anticipate customer needs.
  • Cloud computing and SaaS provide scalable storage and processing power. Institutions can efficiently manage and analyze large datasets without significant on-premises infrastructure.
  • Blockchain supports secure and transparent transaction records, enhancing data integrity.
  • AI tools automate complex analytical processes, allowing financial institutions to rapidly process large amounts of data, recognize trends, and generate real-time insights.
Consumer expectations

Today’s consumers expect instant payments,  mobile payment options, and 24/7 service availability — all of which traditional payments infrastructure cannot provide. Modernizing payment systems enables banks and billers to meet these heightened expectations by offering faster, more convenient, and more secure payments. Conversely, failure to modernize can lead institutions to lose customers to competitors offering superior digital experiences.

Compliance pressures

New and evolving regulatory standard requirements enhance payment system efficiency, security, and transparency, plus they are significant drivers behind payments modernization. For example:

  • The Payment Card Industry Data Security Standard (PCI DSS) mandates strict security protocols for handling cardholder data, requiring institutions to implement advanced encryption, tokenization, and secure storage solutions.
  • The General Data Protection Rule (GDPR) imposes data privacy guidelines and protection. Banks must collect, process, and store customer data respect their privacy rights, and offer transparent consent mechanisms.
  • The Revised Payment Services Directive (PSD2) strong customer authentication (SCA) requirement compels financial institutions to enhance security for online transactions through multi-factor authentication, increasing transaction security and reducing fraud risk.
  • Data residency requirements mandate that certain types of data must be stored within specific geographical locations, influencing how institutions architect their data storage and processing solutions.
Competitive pressure

Major competitors such as fintech companies, digital banks, and non-traditional financial service providers often leverage the latest technologies to offer their customers innovative and cost-effective payment solutions. Gaining a competitive edge to attract and retain customers requires modernization, otherwise, you risk being outperformed by agile, tech-savvy competitors who offer faster, cheaper, and more customer-friendly services.

Demand for efficiency

Maintaining legacy infrastructure is often expensive and prone to inefficiencies. By modernizing payments systems, banks and billers can reduce costs and complexities by leveraging cloud computing, which reduces capital expenditure and dramatically increases efficiency by using AI and ML to automate core business processes. Modernization also empowers institutions to allocate existing resources more effectively and dedicate their focus to strategic growth initiatives, improving their competitive standing and profitability.

Sophisticated fraud tactics

For every financial institution using AI, ML, and other advanced technologies to improve their service offerings, a fraudster uses those technologies to refine their tactics. Traditional payment systems lack the advanced security features necessary to combat these modern cybersecurity threats. Modern payments systems incorporate encryption, tokenization, multi-factor authentication, biometric authentication, and more to prevent criminals and fraudulent activities, providing stronger protection against sophisticated forms of fraud. AI and ML-driven fraud detection systems require updated infrastructure to function effectively.

Interoperability and global standards

International standards such as ISO 20022 support interoperability worldwide. Legacy systems often cannot support the rich data formatting of ISO 20022, limiting financial institutions’ ability to offer consistent and reliable cross-border payment systems. By modernizing, these same institutions can facilitate seamless global transactions, expanding their reach and improving their service offerings.

What is the New Payments Architecture?

The New Payments Architecture (NPA) is an initiative within the U.K. payments industry to develop a new infrastructure for organizing and managing interbank payments. First proposed in 2015 by the Payments Strategy Forum, the NPA originally called for consolidating all current payment types into a single, central, modern ISO 20022-compliant architecture. Over time, the scope of NPA has narrowed to replacing the Faster Payment System (FPS).

The design and delivery of NPA are based on six guiding principles, each one consistent with the larger concept of payments modernization:

  • A robust, resilient, and scalable platform
  • Adoption of the ISO 20022 standard
  • Real-time payments capability
  • Lowering barriers to entry
  • Safe and secure processing to combat fraud and financial crime
  • Ensuring that NPA users benefit from efficiencies

The New Payments Architecture supports several new types of modern payments, including priority payments, instant payments, multi-payments, and bulk payments. Faster Payments volumes will begin to migrate to NPA in 2025, to retire FPS by the summer of 2026.

How can organizations benefit from payments modernization?

Modernizing payment systems is crucial for banks and billers to stay competitive and meet evolving market demands. Some of the ways financial institutions stand to gain from modern payments include:
