Measuring print campaigns with trackable QR codes

Print used to be a black box. You'd ship a flyer, place a billboard, or run an ad in a magazine - and pray.

Dynamic QR codes change that. Every scan is logged with timestamp, country, device, and browser. You can see exactly which channels drove attention, when, and from where.

Use one QR per channel. Not one per campaign - one per channel within a campaign. That's how you'll know whether the bus stop poster outperformed the magazine ad.
