I had this idea that someone who wasn't good at remembering their PIN could have a card with lots of icons with their real PIN under one of them, and the other ones could be random, like this:
Maybe on a real card like this there would be a lot more icons. Then at a glance someone could see their PIN, but someone who stole their wallet, or purse would just see lots of different numbers, and if they tried any of them they would have a much reduced chance of getting the correct one.
You could add in other things like putting the number backwards or having 5 numbers with either the first number to be ignored or the last, which would make it even harder for a criminal to get the right one.
Cash point machines only let you enter a number 3 times or so, I think.
I thought it was an idea; maybe it is too much of a risk having the real number at all.
