 A credit card skimmer is an electronic device that steals your information off of your credit card. They can drain your bank account in a matter of minutes, spend thousands of dollars before you even realize you've been a victim. When you put your card into either a gas pump or an ATM machine, there's an electronic device that reads your magnetic strip. At the same time, there's a pinhole camera close by on the ATM that's watching you punch your pin number in, which gives the criminal access to your bank account. The criminal is putting a cap right over the top of the cap that's on the ATM in which you'd never even know. They're also putting a facial plate, which has the pinhole camera. There's usually a battery of some type. There's a small little motherboard. There's a memory chip in there to record your information. The criminal will come back, remove that apparatus and download that information. It's used to drain your bank account. The information is also being sold on the dark web to other potential criminals that will buy it and go out and do the same thing.
