There are many times when this type of machine could be useful. Occasionally, a bridge club does not have duplicated boards at the time of play, particularly team events. If the machine did not require bar coded cards, I'd buy one in a minute, but I find bar coded cards to be ugly and distracting. (Why are the bar codes printed with visible ink?) My caddies could provide hand records for shuffle-deal-and-play sectional team events at no labor cost and without requiring six times the number of boards we use. The machine can make hand records more quickly from hand-dealt cards than can be done at a computer. Only 39 cards need to be run through the machine, just as with using Deal Master software. That should take about 1 minute per deal. This could be a cheap back-up for a duplicating machine that breaks down just before a game. (I might even want to use it for playing other card games, like Hearts and Spades in 2-table duplicate arrangements.) For single-table home games with "Doop" scoring, this would be a huge improvement over having each individual sorting his hand, which often has some human error on a hand or two. For teaching bridge in high schools, which I do, a full duplicating machine is overkill and not terribly portable. This would be an easy way to create lesson hands. By requiring barcoded cards, this machine has a limited use.
