Brand booth QR opens an instant wheel-of-fortune mini-game. Sponsor sees live entries; prize redemption requires a staff scan, so freebies don't get double-claimed.
Lightweight game loads under a second even on the festival's choked cell network. Redemption is decoupled from feedback (EU Omnibus-safe), and staff redeem the prize via a PWA scan — fraud-proof.
Free tier includes 1 permanent QR and the recovery key — upgrade the slot with the exact modules this case uses whenever you need them.
