Heh, this is exactly how I got on the wrong flight once (the gate changed and I didn’t realize it), the machine didn’t tell the person I was getting on the wrong flight and the attendant didn’t notice. The only reason I discovered I was on the flight is because someone else had a ticket for my seat. The security people were very curious how I did it, both pilots were very pissed (both flights had to be stopped from leaving the gate until they were sure I didn't leave a bag on one of the flights, yay terrorism). But now you can’t do that any more.
