If you have been to a casino or seen movies where they play Black Jack in casinos then you have probably seen a dealer shoe that they use. Several decks of playing cards are simply placed in the dealer shoe and then dealt one by one. Of course a dealer shoes could also be used for other games besides Black Jack and it would be an added insurance that a card shark will not try and cheat by changing cards or dealing from the bottom of the deck. Dealer shoes come in different materials such as acrylic, wood, plastic and metal. When you are dealing with a clear plastic or acrylic dealer shoe then it would be easy for people to see the last playing cards in the deck and to prevent that you could always use a casino cut cards which would be placed behind the last card of the deck and that would cover that card so that no one can see what the card is.
