NIBSS opens up on the tech behind payment rails

When Nigerians transfer money between bank accounts, pay through POS terminals or use fintech applications, they rarely think about the technology connecting these services. However, behind these everyday transactions is a payment infrastructure that allows different financial institutions to communicate.

The Nigeria Inter-Bank Settlement System (NIBSS) has revealed more about the technology behind its National Payment Stack (NPS), explaining how open-source technology is helping power the country’s payment infrastructure.

According to Techpoint Africa, NIBSS built the platform using jPOS, an open-source payment framework developed by Transactility. The development offers a closer look at how Nigeria is strengthening the infrastructure supporting its growing digital financial ecosystem.

##What Is the National Payment Stack?

In simple terms, the National Payment Stack is a shared digital infrastructure designed to help financial institutions process electronic payments and communicate with one another.

Think of it as a common road connecting different banks and financial service providers. Instead of every institution building separate connections to process transactions, they can use shared infrastructure to move money between participating institutions.

The NPS supports instant account-to-account transfers, QR merchant payments, phone-number-based payment addressing and bulk payments.

The technology behind the platform includes jPOS, an open-source framework used to develop payment-processing systems, and jPTS, a transaction switch built on that framework.

The platform also uses ISO 20022, an international messaging standard that allows financial institutions to exchange more structured payment information.

This means the National Payment Stack is not simply another banking application. It is infrastructure operating behind financial services to help different institutions process transactions.

##Why Shared Payment Rails Matter for Banks and Fintechs

Nigeria’s financial ecosystem consists of commercial banks, digital banks, fintech companies and other payment service providers. These institutions need reliable ways to communicate when customers send or receive money across different platforms.

This is where shared payment rails become important.

For banks, common infrastructure provides a way to connect with other financial institutions without independently developing every payment connection. It can also reduce the technical complexity involved in supporting different payment services.

For fintech companies, shared infrastructure creates opportunities to develop financial products without having to build an entirely separate payment network.

For example, a fintech company developing a payment application can concentrate on its customer experience and services while relying on established infrastructure to connect with participating financial institutions.

Another important advantage is interoperability. This simply means different payment systems can work together. Customers can make transfers across participating institutions without needing to use the same banking application as the recipient.

Shared infrastructure can therefore support a more connected payment environment for businesses and individuals.

However, its benefits depend on how well the systems are implemented, maintained and managed. Shared infrastructure must also maintain appropriate security and operational controls.

##Why Open-Source Technology Matters

One of the interesting aspects of the NIBSS disclosure is its decision to build on open-source technology.

Open-source software allows developers to access and work with its source code, subject to its licence terms. This gives organisations more flexibility to customise software rather than depending entirely on a closed product.

According to Transactility, NIBSS has access to the source code and can customise the technology used in the National Payment Stack.

This is significant because payment infrastructure must adapt to changing transaction demands, industry requirements and regulations.

Rather than developing every component from scratch, NIBSS can build on an existing technology framework while developing additional capabilities internally.

However, open source does not automatically mean that the entire implementation is free. Commercial support, maintenance and other services may still involve costs.

The arrangement also does not eliminate the need for security testing, monitoring, updates and technical expertise.

##What This Means for Nigeria’s Payment Future

The development points towards an important direction for Nigeria payments: building infrastructure that can support a more connected and flexible financial ecosystem.

As digital transactions become increasingly important to businesses and individuals, the country needs payment systems capable of handling different transaction types while maintaining reliability.

The National Payment Stack provides a foundation for supporting this development. Its ability to accommodate instant transfers, QR payments and other payment services through shared infrastructure could create opportunities for further innovation.

It also highlights the growing importance of open source fintech in developing financial infrastructure.

Although NIBSS adopted technology from an international provider, its access to the source code gives it room to develop additional capabilities and strengthen its own technical expertise.

This approach could also encourage more Nigerian engineers and technology companies to participate in developing the systems supporting the country’s financial services.

Nevertheless, the technology choice alone does not guarantee a successful payment system. Its long-term value will depend on transaction reliability, security, scalability and the ability to maintain services during periods of high demand.

For ordinary Nigerians, the most important outcome will be whether payments become more dependable and convenient.

Ultimately, the National Payment Stack represents an effort to strengthen the infrastructure behind everyday financial transactions. While customers may never see the systems operating behind their banking applications, their performance will play an important role in shaping the future of digital payments in Nigeria.
