From its very advent before the 19th century all the way up till the computer and internet era, one constant that remained in the game of poker is human dealers and shufflers. Of course, over the last two decades technology has replaced this need for human shuffling which nearly eliminates any errors that could be made otherwise.
The most common type of machines utilized for shuffling cards in poker are the CSM’s or Continuous Shuffling Machines. If the dealer deals out a few rounds, then takes the used cards and puts them into a machine that he is continually taking cards out of, then he is utilizing a CSM.

Standard shuffling techniques were soon considered as weak, and in order to avoid “inside jobs” where employees collaborate with players by performing ‘sketchy’ shuffles, several casinos now utilize automatic shuffling machines to shuffle the cards before dealing. Repetitive motion stress that could cause injuries to dealers too can be avoided by using these machines.
