In this modern world producing state of the art technology, almost all equipment from simple appliances in our house to machines in industries can really give people convenience. However, sometimes these advancements can no longer give us security. Like for instance, bank companies are developing high-end ATM machines, but through modernization, thieves are also enhancing their gadgets.
A video in Youtube shares how an iPhone can steal your ATM pin code without you noticing it at all.
Thermal cameras are really expensive and usually are bulky ones, but with FLIR’s new iPhone case, thermal imaging cameras are now both affordable and discreet. This means that bad guys can use it to see the thermal signature your fingers leave on a keypad and steal your ATM PIN.
Shared by former NASA Jet Propulsion Laboratory engineer Mark Rober, this video has raised awareness for over 4.5 million people about preventing bad people from stealing your ATM pin code.
As he explains in the video, when you press a button with your finger, the button and your finger strive for thermal equilibrium, meaning, heat passes from your finger into the button. Thermal cameras can see the leftover heat signature that your fingers leave in the buttons, and because the heat dissipates over time for about 15 minutes, they can generally tell the order in which you pushed the buttons.
Well, for the good news, Rober also shared how to prevent this from happening. Simply by touching other keys while punching in your code or laying your palm flat across all the keys. Another thing, “metal keypads reflect IR like a mirror. Plus they're highly conductive, which dissipates the heat quickly, which doesn't allow for a thermal signature to be left behind,” says Rober. Good thing ATM machines have metal keypads, but perhaps there’s none in grocery stores.
Always remember, better be safe than sorry.
