"Casino insider tells (almost) all about security". Among some of the cheating methods discussed:

# The infinite hundred-dollar bill: One team took US$1.2 million off a casino in two weeks when it discovered that a new hundred-dollar bill could be fed into a certain slot machine and, if you hit a button at just the right time, the machine would give the player US$100 worth of credit while spitting the actual US$100 bill right back into the player's hands.

# The chip cup: The chip cup looks just like a stack of $5 chips, but it's hollowed out and can hold a few $100 chips. Using the chip cup, a dealer and player working together can make a killing.

# The palm: A player palms a card and trades it with a neighbor to make a better blackjack hand. This trick is decidedly low-tech, but nearly undetectable when done with great skill.

# The specialty code: A programmer who worked on a video poker game snuck in some code that produced an automatic royal flush if a player followed a specific sequence of betting over the course of seven or eight hands.

# Cameraman: Jonas showed photos of one player who was wearing buttons that were actually infrared cameras, capable of capturing the identity of cards as they pass through a shuffle machine. One shuffle machine in particular had a tiny hole that revealed each card, but not to the naked eye. The infrared camera illuminated the card, and the video images were transmitted to a vehicle in the parking lot, where collaborators slowed the video down and could tell their player in the casino which card was coming next. Hitting on 17 is a smart move when you know a four is coming next.
