There are many misconceptions among people about card counting due to the fear that movies and casinos have spread around. In reality, card counting is a fair technique that can be used during gambling. If a person possessing the skill of gambling can do it without coming under the radar of the casinos, there is nothing illegal about it. It is one of the best ways to beat the casino. The casinos may, however, question you if you use any devices to count cards. You be asked to leave the place and can get banned permanently.
