Programming ID cards for access control requires special printer and ID software technology.  To facilitate an access control program, companies and organizations need to use ID cards with magnetic stripe encoding, contactless smart card, or proximity technology.  These ID cards are then assigned to card holders through a database using ID card software.  Cards can be programmed to allow access to offices, specific rooms, or even computer networks.  Card readers are installed at all access points. 

Using the software, system administrators can grant or deny access to individual cardholders making it easy to control and keep track of varying levels of security clearance.  If an access card is lost or stolen it is simple to delete a card from the system using the software.
