A QR Code (Quick Response Code) is a two-dimensional graphic code that, scanned by a smartphone, instantly opens a digital destination — a web page, an app, a form, a transaction. In digital signage, the QR code is the primary bridge between the display and the user's mobile device, enabling the "mobile conversion" model that underpins measurable signage ROI: every scan is tracked, and every downstream action (purchase, signup, download, booking) can be attributed to the originating display.

Livesignage generates dynamic QR codes within playlists and connects them to Progressive Web Apps built on the same platform. The audience in front of a screen is transformed into a mobile audience, and the entire customer journey — from physical impression to mobile action — becomes quantifiable, attributable and actionable.
