The application of digital signage system using smart device

Digital signage is a form of electronic display that shows information, advertising, messages, and TV programs in both public and private environments, including retail stores, hotels, and stations. We introduce another application of digital signage using smart devices. Unlike an existing digital signage displayed at a fixed location, the proposed digital signage system can see in anytime and anywhere using smart-devices if you can use a network service. And because the proposed system gives and takes the information(advertisement data) among smart-devices, the application user can be compensated according to the amount of data transferred to other smart-devices or the usage time of the application.
