Security is primary concern in the user day-to-day life. Everyone wants to be as much as secure as possible. An access control system forms a vital link in a security chain. This access control system allows only authorized persons to access a restricted area. This system is best suitable for corporate offices, ATMs and home security. This paper is aimed to design a digital code lock system with a status display by using wireless communications RF technology and GSM technology. The wireless communications is established by using RF modules and a digital keypad interfaced to the controller.
