Open Payments – Driving Economic Growth

Introduction

Most of the countries while implementing time real-time payment central market infrastructure are adopting second-generation technology. As a result, real-time payments operate within a bank-dependent framework, where transactions are processed only through financial institutions participating in a centralized network. Payment initiation is typically limited to bank-provided channels like Banking Apps, Wallet or Portals. When a payer initiates a payment, the bank verifies the account balance, debits the payer's account, and forwards the credit transfer request to the central market infrastructure. The receiving bank then credits the payee’s account and confirms the transaction. This structured process ensures security and compliance but restricts participation only for banks, limiting accessibility for non-bank entities.

Few countries, like India, have implemented a third-generation real-time central market infrastructure that introduces a more open and inclusive approach, enabling both banks and non-bank entities to participate in payment initiation. In a third-generation real-time central market infrastructure, a payer can initiate a payment through any platform like Google Pay. The central market infrastructure facilitates communications with the payer’s bank to authorize the debit and simultaneously requests the payee’s bank to credit the funds. This process is executed in real-time, with instant notifications sent to both parties. This solution approach allows fintech companies and third-party applications to take active participation in payments, significantly enhancing accessibility and adoption.

By adopting a more open and interoperable approach, a third-generation system enables widespread digital payment adoption, like in India and Brazil. 

The Impact of Open Payments driving economic growth

The third-generation real-time payment platform has revolutionized digital transactions in India by introducing an open payments ecosystem that enables both banks and non-bank entities to participate in real-time payments. This open architecture has enhanced overall economic efficiency due to the following tenets.

Ability for non-banking entities participation, thus Expanding Financial Inclusion

Third-generation based Open Payment Infrastructure, like UPI in Indi, lowers the barriers and enables non-banking entities to take active participation in payment. This enables citizens can initiate digital payment with a smartphone either from a bank account (for banked citizens) or from a wallet (for unbanked citizens) seamlessly. Greater financial inclusion is driven by:

• Reduction of cash transactions proving to be a better economical option for a government.
• Less friction leads to higher consumer spending and better capital rollover.
• Access to overlay financial services and credit lines for businesses and individuals.

Enable Small and Medium Enterprises (SMEs) for digital payment acceptance

Traditional payment systems often require costly infrastructure, making digital transactions expensive for small businesses. Open Payment Infrastructure eliminates such constraints and can be accessed through a smartphone on a digital App and thus enabling micro and small enterprises to move to digital payments from cash-based transaction:

• Accept digital payments without investing in expensive point-of-sale (POS) systems.
• Improve cash flow and reduce reliance on informal credit.
• Pay vendors digitally 
• Ability to check balance and maintain liquidity 
• Expand market reach through e-commerce and digital platforms.

Driving innovation to offer differentiated services driving digital payment 

The open payments framework encourages fintech companies, and technology providers to innovate and develop new financial products and services like: 

• Lending, credit line, mortgages, wealth management, embedded finance solutions
• Offering Payment as a Service for competitive pricing 
• Business specific domestic/cross-border payment solutions like bill payment, government benefits distribution, healthcare, and transportation 
• AI-based use cases like intelligent payment routing, and fraud prevention.

Enhancing Economic Efficiency 

By replacing cash transactions with digital payments, the open payment infrastructure reduces inefficiencies in the economy:

• Lower transaction costs – Minimizes cash-handling expenses and banking fees.
• Faster payment settlements – Instant fund transfers improve liquidity management 
• Enhance financial stability - Reducing the credit risk ratio by lowering default risks
• Greater financial transparency – Digital transactions reduce tax evasion, increasing tax compliance and government revenue while providing better visibility into creditworthiness.
• Financial Inclusion: Enabling non-bank entities for direct participation to serve underbanked population play a direct role.

Why India’s Open Payments Model Leads the Global Real-Time Payments Revolution

Open and interoperable frameworks are proving to be the most effective in fostering financial inclusion, digital transformation, and economic growth. While many systems are evolving towards instant transactions, differences in accessibility, infrastructure, and openness impact their overall reach and adoption.

Bank-dependent central infrastructure, limits direct participation for non-banks and hence hinders adoption. In contrast, more inclusive models like India’s UPI or Brazil’s PIX enable fintech and digital platforms to participate ecosystem accelerating adoption and bringing millions of unbanked individuals into the formal economy.

An API-driven open ecosystem further enhances payment capabilities, enabling seamless integration with emerging financial services. While many real-time payment frameworks primarily serve domestic transactions, future growth lies in cross-border interoperability, which can be met only by UPI-like implementation.

By embracing openness, interoperability, and innovation, payment systems worldwide are paving the way for a more inclusive and digitally empowered financial ecosystem.

RS Software’s role in building UPI

RS Software played a key role in designing and developing UPI, ensuring scalability, security, and interoperability. Key contributions include:

• Architecting the end-to-end third-generation solution 
• Developing a non-blocking, microservices-based infrastructure for scalability meeting the throughput required for 1.3+ billion population.
• Driving financial inclusion through innovative use cases like bill payments and overdraft integration.

Conclusion

UPI stands out as a global benchmark for real-time payments due to its open, interoperable, and innovation-driven ecosystem. Unlike TCH or FedNow, which is limited to banks, and Pix, which primarily focuses on domestic transactions, UPI enables both banks and non-bank entities to facilitate payments across domestic and international corridors, fostering financial inclusion at scale. Its API-driven architecture supports advanced use cases such as recurring payments, digital lending, and government disbursements, making it more than just a payment system—it's a foundation for economic growth and digital transformation.
