From what I've heard, if they do end up scanning the wrong tag (aka for a bag that's not supposed to be on the flight), their scanner thing throws a whole fit (which I guess is a good thing on the noisy ramp). From my understanding of the automated bag systems, your bag gets tracked by the tray it's on using RFID, and not by any of the visible barcodes once it's been scanned.
