A greater number of ATM skimming incidents now involve so-called “insert skimmers,” wafer-thin fraud devices made to fit snugly and invisibly inside a cash machine’s card acceptance slot. New evidence suggests that at least some of these insert skimmers — which record card data and store it on a tiny embedded flash drive — are equipped with technology allowing them to transmit stolen card data wirelessly via infrared, the same communications technology that powers a TV remote control.
Recently, in Karachi, it has been observed that many accounts were being hacked and transactions were done through their accounts. To be on the safe side, you must always check for skimmers before using.
Once you understand how easy and common it is for thieves to attach “skimming” devices to ATMs and other machines that accept debit and credit cards, it’s difficult not to closely inspect and even tug on the machines before using them. Several readers who are in the habit of doing just that recently shared images of skimmers they discovered after gently pulling on various parts of a cash machine they were about to use.
So Always checkout before doing any transaction.
