electronic keypads should randomize the numeric order and that the device should not mirror the letter typed on the inout line or on the keypad.
I used to work at a secure facility with a keypad like this. It was the first stage to getting into the building. You would hit a button and the digits would randomize. I eventually got to the point where I could look at the pad and input my 6 digit code within about 2 seconds. It took me about 2-3 weeks to get that down pat. After that, I would only mess up about once or twice a month.
