The typical system allows or denies the physical entry of a person. Their ability to enter an area may depend on payment or permission. Basic Controls that we encounter every day are turnstiles, such as what you would see with an underground subway system, or a lock, magnetic card, which requires a card programmed to ignore. Other components are parking gates, doors, elevators, and other physical barriers. These types of access control are commonplace.

Many companies and industries are increasing their use of access control systems, particularly those that use magnetic card locks and badge. It is providing greater control access to areas that may contain personal information such as patient data at a medical clinic or a student dormitory. These systems are essential to ensure the protection of people and sensitive information.
