Ad-supported Digital Signage Platform

A complex of web applications and hardware devices (terminals) that help businesses to generate passive income from their digital screens. The product turns businesses’ TVs or digital screens into advertising platforms that can show different kinds of content (images, videos, and RSS feeds) mixed with ads.
