The wireless electronic ordering food system is the typical use of the technology of wireless munication. Using the technology of wireless munication in the dining industry will largely improve the working efficiency and the grade of service. The present paper brings up the plan of the hardware design of the the wireless electronic ordering food system and how to realize. The overall system is made up of two parts, one is the main end and the other is the mobile end. Both sides of wireless correspondence depend on certain hardware platforms. They exchange data according to the protocol which both sides have agreed on before, and the data is transformed in specific frame form. When designing the hardware platform, first analyzes the CMOS chips that will be used in the system. Then, the paper uses Protel 99 SE to design the principle picture and the PCB picture of the system. In this foundation, according to the programming rules of the CMOS chips used in the system, the paper exploits the driving program of the system using C51 programming language in the Windows operating system. By the way, this paper also briefly introduces the software development kits which will be used next， analyzes the limitations of system, and also proposes how to improve it. In order to make the entire system more prehensive， the paper also exploits the serial debugging tool in Visual C++ to display the data from remote end in the window on puter and send data to remote end in the window form. This basically achieves the goal.
