QR & Merchant Fraud India Medium risk

The QR Code Overlay

A fake QR sticker is pasted over the shop's real one, so your money goes to the scammer.

Who scammers target
Shoppers at street stalls, small shops and parking meters
Typical reported loss
$10 – $500 per payment
Why people fall for this
The code sits exactly where you expect it to, and almost nobody reads the payee name before paying.

How it works

  1. 1The fraudster prints a QR code linked to their own UPI ID.
  2. 2They paste it over the shop's genuine QR at a petrol pump, kirana store or parking lot.
  3. 3You scan and pay as usual — the money lands in the fraudster's account.
  4. 4The shopkeeper never receives a confirmation, and by then the fraudster has withdrawn the funds.

Real-world example

Rahul fills petrol worth ₹800 and scans the QR taped to the pump. His app shows the payee as "SK ENTERPRISES" instead of the pump's name, but he taps pay in a hurry. The attendant says no payment arrived, so Rahul pays again in cash — losing ₹800.

  • The payee name in your payment app doesn't match the shop's name or board.
  • The sticker looks freshly pasted, peels at the corners, or sits on top of another QR.
  • The shop has no POS machine or passbook to cross-check the credit.

  • Always read the payee name on the confirmation screen before entering your PIN.
  • Ask the shopkeeper to confirm the name shown on your screen is theirs.
  • Prefer paying by entering the shop's UPI number, or pay in cash if anything looks off.
  • If you already paid, report it in the app immediately and call 1930 (cyber-crime helpline).

Where to report, by country

Already lost money? Report it immediately — the first few hours give the best chance of freezing the funds.
