Bluetooth is a short-range wireless communication technology that enables data exchange between compatible devices without cables. In digital signage, Bluetooth connects screens to smartphones, tablets, beacons and sensors, enabling new forms of interaction and IoT automation.

Through Bluetooth, platforms like Livesignage can synchronize content, activate proximity triggers based on user presence, or collect engagement data for personalized campaigns. The technology contributes to smart and connected environments, simplifying remote management and enabling measurable proximity marketing strategies.
