The bar code system has been working good for the PNWBA, after the cooks meeting you get your boxes and they have pre-printed bar-code labels ready to go, they take one off and put on their list of teams and the cooks gets the rest of them(I think 7 or so). That way if you smudge one you have back-ups, at turn-ins your box is scanned and put into the system, then the computer randomly picks a number that the head judge writes on the box(we use a double blind system). Our soft-ware program allows for multiply scanners and also multiple computers(we use lap-tops) that can talk to each other. Earlier this year we had a whole new program wrote up that makes it very fast and efficient for the head-judge to enter scores, most times results can be had with-in minutes of the final turn-in.
