Access control is the ability to permit or deny entry to your premises without requiring a key. It is highly desireable in companies with a large number of employees or companies with a high turnover rate. Controlling access by means other than key, allows you to grant or remove access permission for single individuals at any time. This removes the need to rekey your business when an employee leaves your employment and eliminates the business disruption caused by getting new keys to the remaining employees.

At its most basic, access is controlled through a single device. Access is granted by a keypad where a personal identification code (PIN) is entered, a card reader where a card is swiped, a proximity detector, or biometrics (finger prints and eye scans). When the device determines that you have provided the proper credentials, it lets you in. Single point devices are the least expensive way to adopt access control. They do not require a physical power connection. Recent technology developments have made single point device very attractive in terms of functionality and cost.

More complex systems are interlaced with various components. The access device may send your credentials to an access control system that verifies the number against an access list. To monitor the door position a magnetic door switch may be used. In cases where exit control is desired a second reader may be used on the opposite side of the door.
