How does UPI work?
Your app links to your bank; to pay you use a UPI ID or scan a QR code, confirm with your UPI PIN, and the banks settle the transfer in seconds.
Is UPI safe?
Yes, when used carefully — payments need your secret PIN, which you should never share. Scams rely on tricking you into approving or revealing it.
Do I need to share my bank account number for UPI?
No. You only share a UPI ID or QR code, so your actual account number stays private.
