There's a QR code sewn into the tag. Scan it and the piece tells you where it came from — the places behind the design, a certificate with its number, and a record of every time that tag has been scanned.
You can't see a real one without owning the piece, so here's the walkthrough. Everything below is a sample.
The locations behind the design, shot with the piece. Swipe through them.
Pro jerseys are made in a numbered run. The tag carries a signed code, and the page checks it against our register before it shows you anything.
Every scan is logged. You see when your tag was first activated and how often it's been read since — so a copied tag showing up in two places is visible, to you and to us. Buying secondhand, that history is the thing worth checking.
The page is read fresh every time. A tag printed for the first drop still shows what's happening now — the next drop, what's live, what's coming. Nothing to reprint, nothing to update. Keep the tag.
