A skimming device is an attachment that fraudsters add to cash machines, so that they can obtain your card information.
The device is normally quite small, and sits on top of the usual slot where you put your card. The fraudster can also insert a pinhole camera somewhere on the cash machine or lay a false keypad over the genuine one, all to capture you entering your PIN.
Keep it safe
When you approach a cash machine, have a look around – check for any obvious signs of tampering at the top of the ATM, near the speakers, the side of the screen, the card reader itself and the keyboard. If something looks off or different - that could be a different colour or material, graphics that aren’t aligned properly or anything that just doesn’t look quite right – do not use the cash machine and report it to the police.
When you're entering your PIN, always assume there is someone looking, whether that’s over your shoulder or through a camera. Always cover the keypad with your hand when you enter your PIN.
