Poker players are all "Known Players" and have all their info on file.

Bellagio poker player walks into a foreign casino with $5,000 chips. The cage calls the Bellagio and they Ok cashing X amount of Bellagio chips, because they know he has them.

"Known" poker player gives them to another "Known" player, no problem. "Known" player gives them to me, I would have a problem cashing them.

Our cage has cashed up to 1/2 million for "known" Bellagio players during filming of poker shows.
