RFID (Radio-Frequency Identification) is a wireless technology that identifies tagged objects without line-of-sight. RFID tags can be passive (no battery, energy harvested from the reader's field) or active (battery-powered, longer range). In digital signage, RFID lets the platform recognize specific objects — a product picked up by a shopper, an exhibit approached by a visitor, a badge worn by an employee — and trigger personalized content on nearby displays.

In Livesignage, RFID readers are first-class inputs to the Flow engine: an RFID event triggers a coordinated display scene, audio cue, lighting change, and optional mobile flow. The combination of RFID-driven content and signage is one of the foundations of smart retail and smart museum experiences — and a typical capability set unlocked by the Phygital license tier.
