NFC (Near Field Communication) is a short-range wireless protocol that enables contactless data exchange between devices held within 4 cm of each other. In digital signage, NFC tags embedded in or near a display let visitors tap their smartphone to instantly open a digital experience — a product page, a coupon, a payment, an identification flow, a contact card.

NFC complements QR codes as the second main bridge between physical signage and mobile devices. NFC is faster (a tap, no scan), more discreet (no visible code), and supports identification scenarios that QR codes cannot. Livesignage handles NFC triggers natively in the Flow engine: a tap launches a coordinated experience on the display and a paired Progressive Web App on the visitor's phone.
