The Rise of UPI and What It Means for Payment Gateways


India’s Unified Payments Interface (UPI) has revolutionized digital payments, processing over 14 billion transactions per month in 2025—surpassing credit cards, debit cards, and mobile wallets combined. For payment gateways, UPI is no longer optional—it’s an essential infrastructure for businesses in India and beyond.

This guide explores how UPI works, why it dominates payments, and what gateways must do to stay competitive in the UPI era.

1. What Is UPI & How Does It Work?

Key Features of UPI:
✅ Instant bank-to-bank transfers (24/7, even on holidays)
✅ No transaction fees (for P2P and most merchant payments)
✅ Interoperable (works across 400+ banks and apps like Google Pay, PhonePe, Paytm)
✅ Mobile-first (QR codes, app-based payments)

How UPI Transactions Work:

  1. Customer initiates payment via a UPI app (e.g., Google Pay).

  2. UPI ID or QR code is scanned/entered.

  3. Bank validates the transaction in real-time.

  4. Money moves instantly (settlement in seconds).

2. Why UPI Dominates India’s Payment Landscape

 

📈 Growth Stats (2025):

  • 14B+ monthly transactions (vs. 2B+ for cards)

  • 300M+ active users (~60% of India’s internet users)

  • Accounts for 75%+ of digital payments in India

Why Businesses & Consumers Love UPI:

✔ Zero cost (No MDR for merchants under ₹2,000 transactions)
✔ Faster than cards (No OTPs for small payments)
✔ Works offline (UPI Lite for low-balance users)
✔ No card needed (Bank account directly linked)

3. How Payment Gateways Are Adapting to UPI

 

✅ Mandatory UPI Integration

  • Gateways must support UPI to remain competitive in India.

  • Example: Razorpay, PayU, Paynet offer UPI AutoPay, QR, and deep links.

✅ UPI AutoPay for Subscriptions

  • Replaces card-based recurring payments.

  • Lower failure rates (no card expiry issues).

✅ UPI for International Payments

  • UPI-PayNow linkage (India-Singapore transfers).

  • UPI Global (NRIs paying Indian merchants).

✅ UPI 2.0 Features

  • Overdraft facility (credit via UPI).

  • Signed QR codes (reduces fraud).

  • eMandates (automated bulk payments).

4. Challenges for Payment Gateways


🔴 Falling Revenue from Cards

  • Zero MDR on UPI means gateways must monetize via:

    • Subscription SaaS tools (invoicing, analytics)

    • Cross-border payments

🔴 Fraud & Dispute Risks

  • No chargeback protection (unlike cards).

  • Phishing scams (fake UPI payment screens).

🔴 Technical Complexities

  • UPI apps fragment the ecosystem (30+ apps with different APIs).

  • Real-time settlement requires robust reconciliation

5. The Future of UPI & Payment Gateways

 

🚀 UPI 3.0 (2026 Predictions)

  • Offline UPI (SMS/USSD-based for feature phones).

  • Smart contracts (automated escrow payments).

  • CBDC-UPI integration (Digital Rupee + UPI).

🚀 Global Expansion

  • UPI in UAE, France, Singapore via partnerships.

  • NPCI’s UPI-X (cross-border interoperability).

🚀 AI & UPI

  • Voice-enabled UPI payments (“Hey Google, pay ₹500 to mom”).

  • AI fraud detection for real-time scam prevention.

6. What Businesses Must Do

 

✔ Enable UPI in checkout (QR, deep links, AutoPay).
✔ Optimize for UPI-first users (simpler than card forms).
✔ Monitor fraud trends (no chargeback safety net).

Can UPI replace cards completely?

For domestic payments—yes, but cards still rule for international/credit.

How do gateways make money from UPI?

Via SaaS tools, FX margins, and premium APIs.

Is UPI safer than cards?

Yes (no card skimming risks) but vulnerable to social engineering scams

Will UPI work for high-value transactions?

Yes—UPI’s limit is ₹1 lakh per transaction (₹2 lakh for some merchants).
