Electronic billboards contain all products, services and promotional information, used to advertise to the public to attract more attention. For example, digital signage can be used in fast food restaurants as a menu board to display items, prices, nutritional value and combined promotional information. Multimedia content can be produced and published through Vecow IT's mission-critical Kanban solution. At the train station, advertisements and live TV broadcasts can be simultaneously displayed on a screen in the waiting area, and passengers on the shuttle bus will have a warning prompt once they arrive at the station. The latest train announcement can be displayed on a screen with many other contents.
