Digital screens are very often installed in facilities such as company headquarters and departments, shopping centers, clubs, hotels, cinemas, offices, etc. They effectively replace traditional advertising solutions. They are slowly eliminating leaflets, posters, advertising folders, banners. Due to the possibility of adapting the Digital Signage system to individual preferences, screens can also be used to display e.g. menu in restaurants, information about promotions in stores, current information from around the world and the country, pro-social actions, etc.
