this is a brute-force PIN hacker type in any 4 digit number and see how fast it hacks it. No letters it will reject it anyway.
don't worry you can't walk into a store and type in 9999 different pins so your pin is secure... for now. Not intended for actual hacking usage. Its very slow because of the spinning mouse wheel but it was really fast otherwise. Also it should only take 2 seconds at most (in turbo mode)
