To receive money on UPI, you never need to approve anything
This is the most important thing to understand about UPI: when someone legitimately sends you money, it arrives automatically. You do not scan a QR code. You do not approve a request. You do not enter your PIN. The money simply appears in your account.
Any situation where you are asked to "accept a refund" by scanning a QR code or approving a collect request is a scam. Without exception.
Why this scam works so well
The refund scam exploits a genuine confusion about how UPI works. Many users, especially those newer to digital payments, do not know the difference between a UPI pay request and a UPI collect request. Scammers exploit this gap deliberately.
They typically call at the right moment — when you have an open complaint with an e-commerce platform, or shortly after a delivery. They have just enough information (your order number, your name) to sound convincing. That information is often scraped from data leaks or bought from shady sources.
Entering your UPI PIN always means money leaves your account.
How SatarkScan directly catches this
The refund scam almost always involves a collect request with a pre-filled amount and a VPA containing words like refund, desk, or return. SatarkScan flags collect requests as a signal, adds weight for pre-filled amounts, and specifically checks for support and refund-style VPA patterns. A QR code from this type of scammer will typically score MEDIUM to HIGH risk.
