Even worse, they can even tell the order in which you pressed them; the “warmest” or darkest key in the picture is the button you pressed last, and the “coolest” or lightest key in the picture is the button you pressed first.
With this knowledge, it’s all but too easy to figure out your code and steal directly from your account.
But how can thieves get these cameras into stores without personnel knowing? Scarily enough, these infrared cameras now come in a small compact form so that they fit right over your iPhone like a phone case. They only cost a couple hundred dollars and are sold at most Apple stores.
Don’t worry, there is a way to prevent this from happening to you!
The trick is simple: when you’re punching in your PIN on the key pad, rest some of your other fingers across the other keys. This way, you’ll throw off the infrared image and a thief won’t be able to distinguish which numbers you pressed.
