POS Machine Swipe Trick Scam

A shop or hotel staff member uses a hidden reader, double swipes or changes the amount on a card machine to take more than you agreed.

You hand your card to a staff member at a restaurant, hotel or petrol pump, and it leaves your sight for a moment. The machine may be swiped twice, a higher amount may be keyed in, or a small hidden reader may copy the card details. Later your account shows a bigger deduction or a purchase you never made. Watching the screen and the card at all times is the simplest defence.

How the scam works

A dishonest staff member takes the card away from the table or counter, often saying the machine is at the back or the network is poor there. Out of your sight, the card is swiped on a second reader or on the same machine twice. Some keep a small skimming device in a pocket that stores the magnetic stripe data in a second.

When the machine comes to you, the amount you see may be right but the slip you sign hides a second charge. In other cases the staff member enters a higher number and shows you only the PIN pad. Because you are in a hurry, tired or in a group, you enter the PIN or sign quickly and move on.

Your bank sends an alert for a small second charge or none at all if the amount is below the alert limit. Later the copied card data is used for online or cloned-card spends. The fraud shows up days afterwards, and by then it is hard to say which shop was involved, which helps the person who copied the card.

An example of what you may see

Example only: At a restaurant a waiter says, 'Sir, the machine at your table is not working. Let me swipe at the counter.' He returns with a slip for Rs 1,850, which matches your bill. Two days later your statement shows a second charge of Rs 1,850 from the same restaurant and a small online purchase from an unknown site that you did not make. The restaurant gives no explanation for the second charge and says the bank must have made an error.

This example is written for illustration. Real messages change their wording, names and links all the time.

3. Keep SMS alerts on for every card transaction.
4. Check your statement within a day of using the card at a new place.
