IoT & Mobile-based System for Business: Quick Service Restaurant

The Internet of Things (IoT) offers new opportunities, innovations and potential for entrepreneurs and existing businesses. Many early-movers deliver better quality, superior services and gain customers as a result. This paper presents an IoT & mobile-based system for business. It was designed and developed in the form of a case study of a quick service restaurant. The Raspberry Pi 3B+ running on Raspbian OS is used as a server. The client side involves the use of mobile devices. The system supports the full features of two approaches including Internet and non-internet model. In the Internet model, the Raspberry Pi server is able to connect to the world through an Internet connection and gateway using the mobile hotspot (3G/4G mobile data plan) of the restaurant's mobile. The evaluation consists of three dimensions usability, functionality and security. The results reveal that all the dimensions were evaluated at a high level. The restaurant owner and customers were highly satisfied with the system.
