UPI evolved from pilot to dominant digital payments system
QR standardisation, BHIM launch accelerated adoption across merchants
Cross-border expansion and inclusion drive next phase of growth
The Unified Payments Interface (UPI) has reached its tenth year of operation, marking a shift in how financial transactions occur across the country. Initially, this project involved developing an application that would allow users to send money from their accounts using their mobile phones. However, over the course of ten years, this innovation became a standard way of conducting day-to-day transactions in the country.
The Foundation
The National Payments Corporation of India (NPCI) introduced the system on April 11, 2016, in Mumbai, with the support of the Reserve Bank of India (RBI). The platform was designed merely as a pilot program involving only 21 member banks. The primary objective was to simplify the process of moving money.
In November 2016, the central government declared the demonetisation of high-value currency notes. This resulted in an urgent and great demand of physical cash alternatives. The Bharat Interface for Money (BHIM) app was released in December 2016 to facilitate this change.
By 2017, many international technology companies began to integrate the interface into their own applications, helping the platform reach a wider audience. The growth in transaction volume was steady. In October 2019, the platform recorded one billion transactions in a single month for the first time. This number continued to rise as more small merchants and street vendors began to use printed Quick Response (QR) codes.
Commenting on this growth, Paramdeep Singh, a financial services expert, stated: "UPI has gone from near zero to ten billion monthly transactions in under a decade, and is now a core financial rail rather than just a payments layer. Its strength is not just scale, but the discipline around interoperability, low cost, and real-time settlement." This growth has allowed the system to handle over 80 per cent of all retail digital payments in the country by early 2026.
Standardisation Of QR Codes
The standardisation of QR codes was another major development. During the initial stages, various applications employed different kinds of codes. The NPCI finally established a common code which permitted any application to make a payment through a single sticker in a shop. This reduced the need for merchants to have multiple machines or stickers.
For non-smartphone users, the system called UPI 123Pay was launched. This allowed users to make transactions without an internet connection, which, in turn, helped alleviate the digital divide in rural locations.
Global Reach And Security Standards
In recent years, the platform has expanded beyond national borders. NPCI has signed agreements with countries like Singapore, France, the United Arab Emirates (UAE), Bahrain, Nepal and so on. These agreements allow users to make cross-border payments or use their local payment apps while travelling abroad.
Security, one of the top priorities, is facilitated through a two-factor authentication (2FA) process. The first factor is the binding of the mobile device to the bank account, and the second is the personal identification number (PIN) set by the user.
Financial Inclusion
UPI has played a role in bringing more people into the formal financial system. Regarding the future of the platform, Prakash Sikaria, founder and CEO of super.money, stated: "Ten years ago, UPI was introduced with a simple objective: to make digital payments instant and interoperable. Over the past decade, it has evolved into the foundational layer of India’s digital economy, processing billions of transactions and driving widespread adoption across the country."
He further added: "While this phase has been defined by scale, the next decade presents a far larger opportunity - deepening usage and expanding access to formal financial services, particularly credit, for the hundreds of millions who remain underserved or relatively new to the system."
The system has moved from a digital experiment into a standard tool for commerce, reducing the daily reliance on physical cash for millions of people.
