Internal information - corporate messages, such as health & safety items, news, and so forth.
Menu information - pricing, photos, ingredients, and other information about the food(s) being offered, including nutritional facts.
Advertising - usually either related to the location of the sign or using the audience reach of the screens for general advertising.
Brand building - in-store digital sign to promote the brand and build a brand identity.
Influencing customer behavior - directing customers to different areas, increasing the "dwell time" on the store premises, and a wide range of other uses in service of such influence.
Enhancing customer experience - applications include the reduction of perceived wait time in the waiting areas of restaurants and other retail operations, bank queues, and similar circumstances, as well as demonstrations, such as those of recipes in food stores, among other examples.
