Every postcard you send has its own QR code. That's how you see what's working.
Each card moves through four steps:
Your results page shows these counts for every campaign. A scan is a real signal: someone held your card and was interested enough to act. Those are the people worth a quick follow-up call.
At the top of your Scans page there's a live feed of your most recent scans — newest first, with how long ago it happened and which design they scanned. A scan means a specific person is interested right now, so each row has a "Who scanned?" button: tap it and Quillus looks up the homeowner behind that scan, so you can knock or call while the interest is warm.
Tip: the neighborhoods with the most scans are telling you where to send your next batch. And the freshest scan in the feed is your warmest lead — start there.
