Access control is defined as the selective restriction to access to a resource, a place, or any other phenomenon.

One is said to have authorization if they have the permission to access the resource whose access is restricted. To learn more about access control Orlando is a good location to consider making a visit to.
Many ways can be used to control how access is controlled. Ticket checkers, border guards, bouncers and other personnel may be used to control how geographical locations are accessed. Turnstile and similar devices may also be utilized. Those who circumvent the controls may be kept out using fences installed around the resource. Locks and keys are major examples of mechanical means used to restrict entry. Access control systems are examples of technological means.
Besides using mechanical and technological means to monitor the way a resource is accessed, physical key management may be added too. Who, when, and where are the three questions that restriction of physical access is concerned with. The system makes a determination of whom entrance or exit is granted. It also determines when and where this happens.
When a location is secured using lock and key, everybody is denied entrance except those who have keys. However, keys can be borne by anybody, even someone who is not supposed to have them because locks and keys do not need further identification beyond the key. No time and date restrictions are also imposed. Locks and keys do not also keep a record of transactions regarding how they were accessed.
Copying of keys is easy and has often causes security breaches besides keys being transferred to unauthorized individuals. Keys are prone to getting lost as people often misplace them. When this happens, the individual is denied entrance or exit from a resource. However, the locks can often be re-keyed to solve this problem. Taking a look at the above weaknesses in locks and keys, it is clear that they are not a very safe and reliable means of controlling how resources are accessed.
Electronic access control was invented as a solution to the weaknesses presented by locks and keys. The use of computers in electronic systems solves most of the problems in mechanical systems. Access is only granted in electronic systems based on the credentials that one enters. The door unlocks if correct credentials are entered and only closes after a given time frame has elapsed. For future references, all transactions on the system are recorded.
Entering unrecognized credential keeps the door locked. The transaction is still captured in the system even if the door does not open. Security personnel is notified by an alarm is the door is opened forcefully. Preventing the door from closing also causes the alarm to be triggered.
This industry is experiencing rapid changes and development. Older systems are being replaced by new, more sophisticated ones. With every new system that is introduced, security is improved while user friendliness is enhanced.
