Being the victim of debit card fraud is a nightmare. What you’re about to see below is an ingenious – yet frightening – way that criminals can steal your debit card PIN using nothing more than an iPhone.
As the video below will show, the thief will use a small iPhone attachment that detects infrared light. Using this attachment, they will take a quick photo of the PIN pad after you have used it and walked away. The resulting infrared image will show which buttons were pressed because they will appear warmer in the image than the surrounding untouched buttons.
Discovering the order in which the numbers were pressed is easier than you may think. In the infrared image, the buttons that were pressed will usually be slightly different shade from one another. This is because the warmer buttons are the ones that were touched the most recently. Using this knowledge, the thief can determine which numbers were touched in which order.
Thankfully there is a simple way to prevent this from happening. Watch the video to see it all in action:
