1. What is a UPI QR Code?
A UPI QR code is a special type of QR code that contains UPI payment details. When scanned with a UPI-enabled app (like GPay, PhonePe, Paytm, or BHIM), it initiates a payment directly to the merchant's bank account.
UPI QR codes are standardized by the National Payments Corporation of India (NPCI). They follow a specific format that all UPI apps recognize, making them universally compatible.
- Format:
upi://pay?pa=merchant@upi&am=100&cu=INR - Components: Payee address (VPA), amount, currency, transaction ID
- Security: All transactions are secured with UPI's two-factor authentication
2. How UPI QR Payments Work
UPI QR payments are simple and secure. Here's the step-by-step process:
- Step 1: The merchant displays a UPI QR code at the counter
- Step 2: The customer opens any UPI app (GPay, PhonePe, Paytm, etc.)
- Step 3: The customer scans the QR code using the app's scanner
- Step 4: The app reads the payment details (payee, amount, etc.)
- Step 5: The customer enters their UPI PIN to confirm
- Step 6: The payment is processed instantly
Speed: UPI QR payments take less than 5 seconds from scan to confirmation.
