My family was checking in at a Hilton in St. Louis in 2001/2002 there was a long line. I went to the ATM & put in my pin combined with my student ID # (8 digits total) just to waste time. Much to my surprise, people's account information came up. There was a scroll bar on the right & 3 people the on screen at a time like so (ish): Name Bank name Account # Balance Last Transaction Amount, Time, Date It is not like the people who came up were relatives, just the last people who had used it. But it amazed me that there are 100million combinations & by dumb luck I picked what had to be the banker/programmer code. It is certainly possible there are multiple codes, but still. People generally only put in 4 digit pins so I suppose they figure 8 would be safe. However there was no other identification (I did not put in a card or doing anything but enter the pin) to gain access to everyone's information. I was only 12 at the time so had no way of buying a lottery ticket.
