India’s Unified Payments Interface (UPI) has grown into the dominant force in global instant payments, accounting for more than four out of every five real-time transactions worldwide. The system’s rapid rise has been fueled by strong government support, widespread consumer adoption, and acceptance across a rapidly expanding network of merchants.
According to MSN, India’s finance minister, Nirmala Sitharaman, said the network accounted for 81% of global real-time payments last year, cementing UPI’s position as the largest instant payments system in the world.
The total volume of retail transactions on UPI has skyrocketed, rising from ₹7,176.9 crore (around $77 million) in FY22 to ₹22,167.9 crore (roughly $2.39 billion) in FY25. Even as UPI approaches saturation in India’s immense payments market, the network has still found room to grow—transaction volume on the system increased by more than 35% last year.
The growth was fueled by several factors, including the prevalence of smartphones, broader financial inclusion, and improved transaction safeguards.
Biometric Guardrails
Among the most notable of these safeguards is biometrics authentication, which was launched on UPI last year. Previously, consumers were required to enter a PIN to authorize transactions. However, India’s regulators added biometric functionality to reduce checkout friction while strengthening transaction security.
This made biometric authentication available to users who opt in, with their data managed through Aadhaar, a digital identity program operated by India’s government. Aadhaar issues citizens a 12-digit number after they provide verifiable biometric and personal data.
Like UPI, Aadhaar is also the largest system of its kind in the world and has frequently been spotlighted as a gold standard for other digital identity systems to emulate.
Fighting Faster Fraud
Sitharaman credited Aadhaar authentication with improving UPI payments, but she also highlighted the persistent challenges of fraud. One reason biometric programs have been slow to gain traction in many parts of the world is that they require both consumer adoption and merchant investment in acceptance infrastructure.
While government backing for Aadhaar and UPI suggests that infrastructure deficiencies may not be a major obstacle in India, gaps in consumer awareness and adoption will likely remind. And since faster payments often equate to faster fraud, challenges related to fraud persist across UPI and other instant payments systems.
To combat this issue, Sitharaman noted that India’s regulators and financial institutions are also conducting frequent awareness campaigns via text messages, radio campaigns, and other platforms.
