Scramble Keypad
Schlage® SERlll-W Scramble Keypad's unique design prevents onlookers from detecting the PIN when it's entered on a keypad. When the PIN is being entered, the LED displays a randomly allocated set of numbers from 0 to 9 to prevent onlookers from deciphering the number. The position of the numbers changes every time the keypad is activated so that only the user standing directly in front of the keypad can see the scrambled digits.
