The paper describes an access system for information display board through web and mobile internet using Wireless Application Protocol (WAP). For accessing the system through web, a web browser was used, and for accessing through cellular mobile, a WAP-enabled handphone was used. The application was developed by using HTML, WML, PHP, and C language. A computer with APACHE web server installed, was used for the server. The display board hardware was connected to the server with a serial connection. The hardware consists of microcontroller and display board which was simulated using an LCD dot matrix. The system has been tested and shows the good result by accessing the system through both of web and GPRS network of telephone cellular.
