New technology makes it possible for predators to read the thermal evidence your body heat leaves behind when you type your PIN number at some ATM machines, car keypads, at the store or even your garage door.

Keep Your PIN Safe

Did you know it’s possible for predators to read the thermal evidence your body heat leaves behind when you type your PIN number at some ATM machines, car keypads, at the store or even your garage door? Heat transferred to the keypad dissipates with time so it’s also easy to guess what order the numbers were punched in.

Fortunately, there are some easy ways to limit your vulnerability:

  • Use your smartphone to open and close your garage door. That’s right, our exclusive security features allow you to control your garage door, locks, lights and much more right from your smartphone.
  • Use “Credit” instead of “Debit” wherever possible in retail establishments. If you must type in your PIN, rest part of your fingers on some of the other keys to confuse a would-be criminal. Using this tactic, the picture above would look like this:

  • Look for ATM machines with metal keypads. Metal reflects heat and cannot be used in this way to steal your PIN number.
