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


I usually speak very loudly while entering my PIN, “1 2 3 4”
I’ve got the same combination on my luggage!
Samsonite!
duh… it’s right there on the briefcase ya goof!
My workmate used to do this 30 years ago.
I started copying him - same funny fake password - when I moved on. Then I left that job after 8 years. I came back to that crew 10 years after that, to where most of them had moved en masse after a calamity, and my casual workmate from back then was doing it a decade later – same funny fake password. I laughed so hard.
0, 0, 0… 0!
