Architecture

UPI runs on the NPCI(National Payments Corporation of India) backbone. PSP (Payment Service Provider) apps like PhonePe and Google Pay act as the front-end. Every transaction routes through the issuer bank (sender) and acquirer bank (receiver) via NPCI's secure switch in real-time.

UPI ID Format

A UPI ID (Virtual Payment Address) follows the format name@bankhandle (e.g., john@okicici, priya@ybl). This eliminates the need to share bank account numbers or IFSC codes for payments.

What is UPI?

UPI (Unified Payments Interface) is a real-time payment system developed by NPCI that allows instant bank-to-bank transfers via mobile apps using a Virtual Payment Address (VPA) like yourname@bank. It works 24/7 including holidays.

Which UPI app has the most users?

PhonePe leads with approximately 47% market share by transaction volume, followed by Google Pay at 34%. Together they handle over 80% of all UPI transactions in India.

Is UPI free to use?

Yes, UPI person-to-person (P2P) transactions are free with no charges. For merchant payments (P2M), transactions below ₹2,000 are free. The government has allocated subsidies to keep UPI free for consumers.

Can I use UPI abroad?

Yes, UPI is now accepted in 10+ countries including Singapore, UAE, France, Sri Lanka, Nepal, Bhutan, and Mauritius. You can scan local QR codes with your Indian UPI app to pay in the local currency.

What is UPI Lite?

UPI Lite is an on-device wallet feature that allows small-value transactions (up to ₹500) without a PIN, making payments faster. UPI Lite X extends this to work offline without internet connectivity.

What is the UPI transaction limit?

The standard UPI transaction limit is ₹1 lakh per transaction. For specific categories like tax payments, IPO, and insurance, the limit is ₹2–5 lakh. UPI Lite transactions are capped at ₹500 each with a ₹2,000 wallet balance.

How safe is UPI?

UPI uses bank-grade 128-bit encryption, device binding, and 2-factor authentication (UPI PIN). Transactions require both the registered mobile number and UPI PIN. NPCI monitors transactions in real-time for fraud detection.
