[..] At least Sparkasse and HypoVereinsbank and IIRC also Postbank allow changing at the ATM terminal. And a birthday isn't as idiotic as 1234 or 1111, as long you assume a standard pickpocket doesn't know you personal data (OK, your ID-card within the same wallet... maybe no good idea. Then not your own birthday but from a person or your cat you can remember, or better your wedding day, which normally would be forgotten always ;-) > Now, this is a completely different question which does not have to do > anything with the pin's length.

Then I chose one and the same "good" PIN for all four cards which I don't need to write down anywhere and everything is OK.
