BINGHAMTON, N.Y. (NEWS10) – Wearable devices could be sharing your ATM pin, a Stevens Institute of Technology study found.

Researchers say wearable technologies, like smartwatches and fitness trackers, along with computer algorithms could crack private PINs and passwords with 80 percent accuracy on the first try and more than 90 percent accuracy after three tries.

The study found that hackers could reproduce the hand trajectories of a user, who is wearing a wearable device, and recover the secret key entries.

Researchers experimented with three different kinds of keypads, detachable ATM pad, keypad on ATM machine, keyboard, and wearable devices.
