Unified Payments Interface (UPI): Significance & Challenges

Table of contents

The Unified Payments Interface (UPI), developed by the National Payments Corporation of India (NPCI), has redefined India’s digital payments landscape. Handling over 58 crore transactions daily has become the backbone of India’s cashless economy. However, frequent downtimes in March-April 2025 exposed systemic vulnerabilities, raising questions on resilience, regulation, and sustainability amidst India’s vision of a “Digital India.”

Understanding the Unified Payments Interface (UPI)

Architecture: UPI is built on the Immediate Payment Service (IMPS) framework and acts as an interoperable, real-time, 24/7 payment system.
Role of NPCI: NPCI acts as the central switch, routes transaction messages between banks, enforces encryption standards, but does not store or directly process PINs.
Involvement of Banks: Banks must integrate with UPI as Payer and Payee banks, handling account authentication, transaction authorisation, and fund transfers.
Involvement of Payment Service Providers (PSPs): PSP apps like Google Pay, PhonePe, and Paytm provide customer interfaces and connect users to banks but do not hold funds.
UPI Lite: UPI Lite enables small-value, offline transactions (up to ₹500 per transaction, ₹2,000 daily) without PIN entry, with final settlement validated by banks and NPCI.

Impact of UPI on Governance and Transparency

Financial Transparency: UPI improves transaction auditability and tracks government spending to ensure funds reach beneficiaries through Direct Benefit Transfers and welfare schemes.
Direct Benefit Transfer (DBT): UPI streamlines government subsidy transfers directly to recipients, eliminating intermediaries and enhancing the accessibility of schemes like PMGDISHA & Jan Dhan Yojana.
Curbing Black Money: UPI formalises the economy, hindering black money. Promoting cashless transactions enhances tax compliance and fosters a transparent financial ecosystem.
Boosting Government Efficiency: UPI enables instant payments for taxes, utilities, and fines, reducing administrative overhead. It also ensures benefits reach intended recipients via platforms like e-RUPI.
Data-Driven Policy Making: UPI’s transaction data provides valuable insights for crafting responsive policies, especially in sectors like agriculture, healthcare, and education.

Significance of Unified Payments Interface (UPI)

High Transaction Volume: UPI recorded 18.3 billion transactions worth ₹24.77 lakh crore in March 2025, underscoring its dominance in India’s digital payment landscape. (NPCI data)
Financial Inclusion: 45% of UPI transactions originate from Tier-2 and smaller cities, indicating the widespread reach and adoption of digital payments beyond urban centres.
Global Expansion: UPI’s integration with Singapore, UAE, Nepal, and France boosts India’s global digital payments ecosystem and enhances cross-border payment capabilities.
Affordability and Instant Transfers: UPI offers zero-cost, real-time, peer-to-peer (P2P) transactions, making it accessible for individuals and small businesses.
Boost to Digital Ecosystem: UPI’s interoperability has paved the way for fintech innovations, enabling Google Pay, PhonePe, Paytm, and other Payment Service Providers (PSPs) to build their platforms.

Challenges Facing Unified Payments Interface (UPI)

Centralised Vulnerability: UPI transactions depend on NPCI, creating a Single Point of Failure (SPoF). If NPCI experiences issues, all Payment Service Providers (PSPs) and banks are affected.
Systemic Outages: Excessive “check transaction” requests can overload NPCI systems, causing significant downtimes, as seen in March-April 2025, affecting millions of GPay and PhonePe users.
Banking Disincentives: The zero MDR policy prevents banks from earning transaction fees while incurring ₹0.80 costs per transaction, reducing their motivation for system reliability and upgrades.
Weaker Monitoring Standards: Unlike commercial card networks (Visa, Mastercard), UPI lacks stringent SLAs and real-time regulatory oversight, leading to slower responses during system failures.
Cybersecurity Threats: With a 24% rise in digital frauds in 2024, UPI must enhance its security framework and encryption protocols to safeguard user transactions and prevent financial crimes.

Key Initiatives to Promote UPI

UPI 123PAY – Bridging the Digital Divide: Enables UPI services for feature phone users without internet, empowering rural and digitally underserved populations.
UPI Chalega Campaign: NPCI’s awareness initiative promotes safe and easy UPI usage and educates users about features like UPI LITE for small-value transactions.
UPI for Secondary Markets: Introduced to simplify IPO applications and equity investments via UPI, encouraging broader financial participation.
Credit on UPI & UPI-ATM (ICCW): Integration of RuPay credit cards with UPI and Interoperable Cardless Cash Withdrawals boosts digital payment flexibility.
UPI LITE X & Digital Rupee Integration: Enables offline payments using NFC-based UPI LITE X and QR interoperability with the Digital Rupee (e₹) for seamless retail transactions.
Global Expansion of UPI: UPI is now accepted in UAE, Singapore, France, Bhutan, Oman, etc., with MoUs (E.g., Google India-NPCI International) to scale remittances and tourism payments.

Way Forward

Strengthen Infrastructure and System Reliability: Scale up NPCI’s capacity to handle increasing transaction volumes, with redundant infrastructure and backup systems to minimise downtimes.
Enhance Cybersecurity Framework: Upgrade encryption protocols, implement multi-factor authentication, and deploy AI-powered fraud detection to ensure user security.
Sustain Financial Viability of Banks: Revise MDR policies to allow minimal fees for banks and explore incentive schemes to maintain system performance and support tech adoption.
Boost Digital Literacy and Awareness: Launch targeted campaigns in rural and semi-urban areas to educate users on secure usage of UPI and digital payment practices.
Accelerate UPI’s Global Expansion: Fast-track international partnerships and bilateral agreements to integrate UPI with more countries and enhance global digital payment capabilities.

UPI is central to India’s goal of becoming a “Digital Vishwaguru.” However, its vulnerabilities to downtimes, cyber threats, and system overloads call for urgent reforms. Strengthening infrastructure, ensuring financial sustainability, and enhancing cybersecurity will enable UPI to evolve into a secure, robust, and world-class payment system, advancing India’s vision of “Digital Empowerment for Every Citizen.”
