61 pins are used by 1/3rd of all people. So statistically, if I steal 61 debit cards, assuming I have 3 tries, and assuming people choose their own pin, I should be able to get cash off one in expectation.

I think the situation for actual PIN codes may be slightly better than suggested; sometimes (in the UK at least) your bank will assign you an initial PIN and I expect many people won’t change it, and by using a dump of passwords, you’ve probably captured some people who have created throwaway accounts and chosen the easiest possible password.

I moved to Switzerland, and, well, PIN codes for credit cards are 6 digits here by default.

And now I'm asking myself why noone else does this. I don't see hordes of Swiss people complaining about being unable to remember a 6-digit PIN at least.
