Vending Machine API
API for vending machine operators to issue 7Stamp loyalty stamps/bonuses at unattended points of sale — no cashier, no app. Customer journey: buys item → machine calls API and displays a QR on its screen (or prints it on a receipt) → customer scans it with their phone → stamp/bonus lands in their Apple/Google Wallet card in ~15 sec. Same mechanic as existing API-issued QR (used today for Receipt QR / Delivery Inserts) — one API call, one link, placement is on the vending machine's screen/printer instead of a POS receipt. No new hardware or certification needed on 7Stamp's side.
