Development of an easy payment system based on IoT gateway

In this paper, we proposed an easy payment system based on IoT gateway. The proposed payment system designed the process and constructed the system based on OneM2M. Through simple experiments and test, users can easily order menu of shop through Smart Device. Store manager can easily check menu of shop and order status through IoT Gateway. In addition, since IoT gateway and IoT server based on OneM2M standard are developed, it is possible to construct IoT system more easily by using various sensors in the future.
