How can I pay with UPI?

To make a UPI payment, first launch your UPI app on your smartphone. Look for the 'Pay' or 'Send Money' option. Next, enter the recipient's UPI ID, mobile number, or scan their QR code. For example, using the Paytm UPI app, you can choose 'Scan & Pay', 'To Mobile or Contract', or 'To Bank or Self A/c' under the 'Banking & Payments' section on the home screen.
