The Cartology HCF campaign was a large-scale, interactive initiative that allowed the public to engage directly with digital screens by scanning a QR code. Participants could enter personalised messages that would be displayed on screens in their local area.

HCF curated the entries, selecting which messages to display and where they would appear. A single HTML zip file was provided for each state, ensuring that the correct creative played on the appropriate screens. This dynamic campaign was successfully executed across hundreds of screens in 5 states across Australia.
