Some POS agents can send your ATM card details to fraudsters when you go to them to make transaction at their terminal.
All you need do is to be careful and extra vigilant.
• HOW IT IS BEING DONE
When you go to a POS terminal to make a transaction, he/she will collect your ATM card and slot it into an ATM machine. After few seconds, he/she will tell you that the POS machine is malfunctional (i.e not working properly). He/She will tell you that you should wait while he/she bring another POS machine inside.
When he/she goes inside, your ATM card will be snapped (including the surface and below) with a smartphone. He/She will surely come out with another POS machine, but you will not know that your ATM card had been snapped and sent to fraudsters! The fraudsters will now use your ATM card details and make transactions online!
