We were told by the casinos and card company MFG (in Billings, we visited for research on one certain card we were told didn't exist) that the casinos did NOT put the bar codes on the cards. But they were added when ordered by the casino. We saw boxes of cards on the shelves. I am not here to argue. Most cards were stored in a large machine/computer, at the casino and the casinos took your name, issuing the cards only once a week. You were to pick them up in the sometime future. Pat
