Why is my PIN pad scrambled? The numbers are always in a different position.

A scrambled PIN pad hussles the layout of the keyboard every time you use it. This protects against so-called 'smudge attacks': Attackers will not be able to guess your PIN from the marks your fingers leave on the screen. It will also protect your PIN code from 'Shoulder Surfers': Attackers who try to guess your PIN by observing you while you enter it.
