... to magnetic cards in the future, and they have just started on the work. I spotted the white cards shown here on the way across the casino floor to the card booth. When asked what was up, the lady said the white cards were being issued as a transition card from the slotted (Hollerith) sytem to a magnetic one. They had more of the black illustrated cards (I saw an open box) but were not using them. I went on to sweep the rest of the casino (you never know what else you might find) when I saw one of the black illustrated cards and saw it had a magnetic stripe. Why were they replacing the cards that had punches and a magnetic stripe with different cards that has punches and a magnetic stripe? I suspect they were issuing the black illustrated cards without activating the magnetic strips on them and have to replace them or have people complaining their cards don't work in the magnetic boxes. I also found the IGT Gaming System card on a machine there. Some slot tech must have forgotten it. If anybody wants white Stardust cards, I have lots of traders.
