Abstract: Current wireless communications enable people to easily exchange information directly, while web services provide loosely coupled and platform-independent ways of linking applications across the Internet or Intranet. This paper represents an integration of wireless communication technologies and web services technologies to realize a food ordering system.With the help of both desktop PCs and mobile devices such as PDAs, it implements wired and wireless data access to the servers and food ordering functions over a wired/wireless integrated local area network in this system.To ensure the security of the system, the secure web service architecture and some security strategies to ensure mobile communication security are discussed.Web services-based wireless applications on mobile devices provide a means of simplicity, improving efficiency and accuracy for restaurants by saving time, reducing human errors and efforts etc.
