Two bins from a made-up coffee roaster, each with its own QR code. Point your phone's camera at one and the count next to it goes down, on this page and on anyone else's. The third bin is already below its reorder point, so you can see what the owner gets, and click through to reorder the way they would.
Picked so far today: 0. Bins restock themselves at zero and the demo resets each night, so scan as much as you like.
Orders arriving from your marketplaces, scan-to-pack with supplies deducting themselves, reorder emails with one-tap links, a log by person, all inside your own Google account.
