Amid a spike in reports of credit card theft devices, viral footage captured a shopper confronting a 7-Eleven cashier over an alleged skimmer.
Skimmers are devices installed on card readers that collect card numbers, allowing thieves to recover and use the information for fraudulent purchases. They are most often camouflaged at ATMs and gas stations, but scammers can also target retail stores and restaurants, according to Forbes.
The card skimmers can often transmit information through Bluetooth. That means a thief can return to the same location and download the data without contact, whether they are sitting in the back of a car or simply hovering nearby.
