What is the card machine scam?

Step-by-step: how the scam happens

This scam involves tampered card machines or manipulation during the payment process. The most common types include:

Overcharging: the scammer quickly enters a higher amount to trick the customer.

Double charges: the scammer claims the transaction didn’t go through and asks for it to be repeated.

Card cloning: fake machines record card data for future use.
