Public Interface Studies II
( Pin code input pad on a Deutsche Bank ATM in Berlin Prenzlauerberg.)
Hmm … isn’t that strange? It seams like everybody has a one, nine or zero in his/her four digit pin code and very few people a six or a two. Do banks have any special algorithms on generating pin codes which are simple to learn by heart? Or do we have a security issue here? Yes, true my code does not contain two, four or six. Am I in trouble now … ;-)

Very interesting! Perhaps the most enigmatic secret was just now revealed :-)
I don’t know why, but I’m thinking about Mythbusters and their censored report: http://tinyurl.com/5dc5ed

depending on the user interaction, could 1,9,0 be common buttons for navigation prompts? if so, that may be one reason why they are more worn down that the other keys

yes @merzmensch, they seam to be in trubble. part of the rfid technology as well as the very old standard magnetic cards.
good point @halvfet. all standard navigation goes trough some extra keys next to the screen but since you want to withdraw a specific amount of money ( other than 100, 200, 300, 500, etc) you have to punch it in on the number keypad. haven’t thought about that. it probably means that these people go for 150,- , 350,- or or just 50,- maybe even 900,- (1000,- is probably the limit.) i will check next time if they have 250,- and 200,- as default option. that would maybe prove your point.
Thx!
