I feel better player surveillance is essential in casinos. Casinos have to ensure that all players are following the rules and regulations of the game. They also have to ensure that players are not cheating or engaging in fraudulent behavior. For example, in Baccarat, any attempts to mark or tamper with cards are strictly prohibited. If a player is caught cheating or breaking the rules, they may be kicked out of the casino, and the incident may also be reported to relevant authorities.
