A new method of PIN entry 'OneButtonPIN' has been tested by researchers at the University of Waterloo and the Rochester Institute of Technology.

OneButtonPIN counts up using vibrations, the user then presses the button when they reach the right number for the digit of the PIN, this is repeated for each digit.

The research showed that it was more accurate for Blind and Low Vision users and reduced the ability of onlookers guessing the pin.

The more entry methods explored and implemented; the more inclusive PIN entry can be.
