Use two fingers to put in your PIN

One actually presses, the other one doesn’t

You could generate an absurd amount of possible PINs that could work on your card, giving any PIN peepers a seriously hard time, should they somehow have the intent to get ahold of your card and PIN through spying and pickpocketing

    My method is to put four fingers over the four digits, and keep them in place while moving all of them for each press.

    Assuming a four-digit code, your method generates 24=16 possibilities; mine generates 44=256.
