Short version. A brand that sells through hundreds of retailers has never known which shelf sends people online.
Print that reports back
A brand that sells through hundreds of retailers has never known which shelf sends people online. A different QR per store, per shelf, per bag, each a tracked link, answers it in a week — and the answer often surprises.
Real estate, events, restaurants
A hoarding QR per road, a poster QR per college, a menu QR per table: the same idea. Opens from a city you did not print in mean the code was photographed and forwarded.
