Casino Chips are form of currency designed to improve all round security. Mostly, they are tied to the casino where they were obtained.
Casino chips came about during the 1880’s. Prior to that, real money was used mostly but some casinos did introduce crude currency systems. Pieces of ivory wood, or bone were used to simulate money. The first chips were made out of clay and even today a clay composite is widely used. Some casino chips are ceramic to give them an appealing edge.
Having chips as a currency avoids a lot of security problems. They are intended for use in the casino where the level of security is usually very high. When entering the casino gamblers can purchase chips from the cage to suit their type of gaming. Unlike normal currency there are some very high value chips. So, the idea is that you cash your casino chips in when leaving the casino.
