It is a very effective way to attract and interact with consumers in the form of customized messages. These messages can target customer interests and thus have the capability to influence buying behavior.

These advantages make digital signage a reliable alternative to other advertising media such as posters and banners. It has positively impacted sectors, such as banking and transportation, while some of the industries experiencing large-scale impacts of digital signage deployments are retail, hospitability, and healthcare.
