I wonder how much traction you could get out of a simple "Please, send me your name, credit card number, expiration date, savings account number, and PIN. --The Bank"
I wouldn't be surprised if a few people fell for it. I was in the post office once and the clerk blurted out to some lady at the counter "I don't want to know it!" because she started saying her passcode out loud after he told her she'd need to have it for the transaction she was making. They have those keypad deals for that, and she starts telling it to him and for everyone to hear.
