The wireless electronic ordering food system is the typical use of the technology of wireless communication. Using the technology of wireless communication 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 langua
