A Randomized Keypad

This product seems like one of those inventions that should've been introduced a long time ago. It's a randomized numerical keypad. It just makes it more difficult for people to steal your pin or access code. The numbers are placed in different spots every time you turn it on, making it hard for anyone to guess what you're typing in. However, it might also require people to slow down a bit.

Normally, when most people input a pin or code, they're doing it almost through pure muscle memory. So, in that regard, it might take a bit of patience and a little extra time to use.
