High Security Randomised Scramble Keypad

The Scramble keypad's design prevents onlookers from detecting the code being entered. Unlike a conventional keyboard, there are no surface markings for the keys. Only a user standing directly in front of the keyboard can see the scrambled digits.

An internal viewing constrictor ensures that the numbers displayed by LEDs under each key are visible only by the person standing directly in front of the keypad. Even someone standing beside the user is unable to see the numbers, as the user’s head obscures the view.

As the digits are scrambled observing which keys are pressed will not reveal the code or PIN to a potential intruder. Each time the Progeny Scramble keyboard is used, the digits 0 to 9 are allocated at random to the keyboard’s 10 keys. There are over 3.6 million permutations! This also ensures that the keys wear equally, even if the same code is always used.
