To change for the better of the menu board which is not applied ICT technology, we present automatic ordering system using by CMOS touch technology. Optical touch can be an ambiguous term because there are several different methods of using light to detect touch. The progress that has been made in CMOS technology over the past decade has made it the preferred technology for high speed inspection. CMOS infrared (IR) cameras are placed on top of a display, looking across the surface of the display in order to detect the presence of a touching object. In this paper, we present the process of choosing the menu by the CMOS infrared technology, and the communication with the sever(POS in this case) using WIFI. The propsed system included 5 parts: hardware part, touch technology part, presentation of menu part controlling the device part, and ordering commnunication part. The advantage of the proposed system is that lower cost by using LED instead of electronic display and energy efficient.
