Casino Insider Tells (Almost) All About Security
Disclaimer: I used to work for the largest chain of casinos in the country taking care of the machines that actually talked to all the slots and games in the casino.
Casinos would like you to believe in Ocean's 13 size IT rooms and facial recognition and such. The truth is that most casino security is low-tech (cameras and people). The largest cheating ring that was broken up recently involved a gaming commission, law enforcement, and the casinos themselves busting a partnership between outside cheaters and the employees working at the table. You have to remember, the states view cheating as bilking them out of the exorbitant taxes they get to rake from casinos since casinos are evil like cigarettes and okay to tax at obscene rates.
If some casino is using facial recognition scanning software etc, they probably are just peeing money down a drain. More likely, its hype designed to scare off cheaters. I think its a dumb idea to create this image though.
In Stalin's Russia, there wasn't a dossier on everyone, but the fear of a dossier on everyone was what helped keep the masses in check. Cultivating a fear in casino goers that they are under watch at all times and being scanned isn't in the interest of the big casinos. Casinos are the last place you are free to be free. You can let your hair down, have a politically incorrect drink, and inhale politically incorrect air.
Go to a casino, have fun, and remember that the cameras are more likely watching employees than they are watching you.
