Credit Card Scammers Targeting Retailers, Self-Checkout Lines

Last month, thieves at Walmart stores in Virginia and Kentucky used skimmers — devices placed over credit card readers — to gather information and pin numbers and make duplicate cards. A skimmer works by recording the digital information from a swiped card, and a micro-camera captures the pin number. Those are sent to the thief via Bluetooth or removed later. In a security video, one man shields his partner, who pulls the skimmer out of his jacket and pops it in place. The whole operation takes two seconds. They made off with as much as $20,000 from at least 38 victims. See more at CBS News.
