An interactive rewards card system embedded in smart phones and a cloud server

In order to make a rewards card system more convenient, we embed it in a system over Internet by using smart phones and a cloud server, which installs Web pages and database (DB). The rewards card system developed in this study provides interactivity, security, and consistency without sacrificing response time. While the system is made fully interactive among clients, merchants, and the cloud server, it also keeps security and consistency due to the sophisticated co-design of the system and adequately restricting access to DB. We verify the system running and evaluate the usefulness.
