POS Terminal Tricks at Shops and Fuel Stations
Wrong amounts, 'failed' payments charged twice, and cards taken out of sight: how people get overcharged or cloned at shop and fuel station card terminals, and what to watch for.
Most card payments in shops are routine. A few go wrong, sometimes by mistake and sometimes on purpose. The fixes are simple habits at the moment of payment.
Common tricks
- Wrong amount: an extra zero, or a different price from the shelf.
- "It failed, try again": both attempts go through.
- Card taken out of sight, for example at a fuel pump or restaurant, where it can be copied.
- Watchers noting your PIN. See protecting your PIN.
- Tampered terminals with added skimming parts.
Habits at the terminal
- Read the amount on the screen before paying.
- Keep your card in sight, or bring the terminal to you.
- If a payment "fails", check your banking app before trying again.
- Keep receipts for larger purchases.
- Check alerts after paying. See spotting unauthorised charges.
If you were overcharged
Ask the merchant to refund, then dispute with your card issuer if needed. See disputing a card transaction.
If you run a shop, train staff to handle failed payments carefully so genuine customers are not double charged. See training staff.

Frequently asked questions
The payment 'failed' but I was charged. What should I do?
Keep the receipt or screenshot, check your statement, and ask the merchant for a refund. If they refuse, dispute it with your card issuer.
Is it risky to let staff take my card away?
Yes. Keep the card in sight so it cannot be copied or swapped.
How do I spot a wrong amount?
Read the amount on the terminal screen before tapping or entering your PIN.
