As an iPad-based app, iCHEF is a point-of-sale system designed for restaurant owners and serving staff. With it, they can monitor every single process, from ordering to the bill. Providing an easy-control interface with comprehensive functions, the app makes serving processes in restaurants significantly smoother. By transferring each order into different data analyses to identify sales trends or dining habits related to customers, vital statistics are being tracked and provide useful information. The system allows for an 48 hours offline operation and stable service in case the user has no Internet connection or the device is not working properly.
