Differences

Jul 2, 2007
Here's one thing that I've never understood in life: why are some keypads and number pads inverted while others are not?

  


It just seems strange that no matter what you use: ATM, keyboard, phone, etc., the keypad that you are entering your information into is different every time.

Maybe I missed the memo on this growing up, but is there a standard on when you should invert the numbers and when you shouldn't?
