IOT based smart restaurant system using RFID

Technologies of identification by radio frequencies (RFID) contribute in many IOT application scenarios, such as healthcare systems and smart retails. This paper proposes a system for smart restaurant. In a four layered architecture the RFID technology is used to handle the order delivery activity. The protocol used is the hypertext transfer protocol (HTTP) and the application service relies on a representational state transfer (REST) web service. This system has been demonstrated to be realizable by some simulation using the Raspberry pi board and the ITEAD PN532 NFC module.
