HOW DOES IT WORK?
When an ATM is not working, a person posing as a technician, a bank employee or a police officer asks users to re-enter their PIN code so he or she can memorise it and then steal or swap their card.
WHAT MEASURES CAN BE TAKEN TO PREVENT IT?
Never accept offers of help from another person when you are using an ATM
Never disclose your PIN or let anyone else see it
Use your free hand or wallet to hide the keypad as you enter your code.
