About a week ago, I stopped by my local bank’s ATM machine. As I lined up behind a couple of other customers, I felt an air of tension and unease. The woman at the ATM machine was glancing cautiously at people behind her through the mirrors placed on the machine. Although I understood her caution, I wondered if she knew that a more threatening thief might not be directly behind her. Rather, the thief could be sitting comfortably at home reading the sensitive data off of her ATM card through a magnetic strip skimmer while obtaining her PIN number with a tiny, thermal camera placed on the ATM machine.
