<prompt> Human: Has anyone else used an ATM that allows them to enter the wrong PIN and still go through almost the entire transaction? After entering the wrong PIN my credit unions ATM will let me select my account, enter the type of transaction, and if Im trying to withdraw money will even let me choose how much to withdraw, then it whirs for a few seconds and finally tells me: Sorry, wrong PIN. I cant actually withdraw any money, but its still annoying to go through the entire transaction only to be told at the very end wrong PIN. How does a system get designed this way? update I just called customer service and the lady I spoke to unlocked my card, then gave me the number for card services where I was able to set up a new PIN, this time one I wont forget. No, its not my birthday, nor the combination to my luggage ;  <response>: Its because it gathers all the info and sends the request to your bank, which then rejects your pin. It doesnt do multiple requests where it verifies pin, then proceeds.
