166. The number of Pin Numbers to know in Germany
-your EC bank card pin (all are 5 digits)
-your bank card pin for telephone banking
-your bank card pin for online banking
-your cel phone pin (4 digits)
-anonymous TAN no.s for numerous banking transactions
(this is pretty funny, they send you in a very secret envelope a list of 100 TAN numbers with 5 different coded numbers for each TAN, you must never lose this (keep it safe and heck you will never be able to memorize these numbers! You must use them to do any banking transaction with your bank.)
-your wireless internet

note: and you can't try to change these pin numbers, you're stuck with each one so you better just start memorizing!
