3C Canteen

3C Canteen — Cashless. Connected. Quick.

Replace cash and ID cards with a single tap. Diners carry a 3C NFC bracelet (or a printed QR card) linked to a prepaid balance. Staff tap it on a phone at the till and the meal is paid in under a second. No cash to count. No PIN pads. No queue at the kiosk.

Built for schools, universities, corporate cafeterias, and any food-service operation that runs a fixed roster of customers, 3C Canteen brings tap-to-pay convenience to environments where cards and cash both fall short.

Three apps in one.

For diners and parents:
- Claim a 3C bracelet by tapping it to the back of your Android phone, or by scanning the QR card.
- Top up via Stripe card, MTN Mobile Money, or Orange Money — whichever your canteen accepts.
- See real-time balance and full transaction history.
- Set per-bracelet labels for "Sophie's lunch" or "Marc's snack budget" so each child or family member has their own meal-card identity.
- Lost or stolen bracelets are deactivated in one tap. Remaining balance carries over to the replacement.

For canteen operators:
- Onboard once, manage many sites — run multiple canteens from one operator account.
- Build a master product catalog, then attach products to each canteen with their own price and stock flag. Currency follows the canteen.
- Plan daily menus a week ahead in a clean per-day card view, or post a persistent shop list of always-on items.
- Manage your team: PIN-only sign-in for staff, scheduled shifts, on-the-fly suspension, role-based permissions for cashier and NFC writer.
- Reconcile end-of-day takings, see flagged transactions, export reports.

For floor staff:
- Sign in with a 4-digit PIN at the start of your shift. Sessions expire automatically — no risk of a forgotten log-out.
- Charge shop items, run check-in and check-out at the door, and prompt the diner to accept or reject the transaction on screen.
- Goes offline gracefully: when service drops, transactions queue locally on the device and replay the moment you are back online. Nothing lost. Nothing duplicated.

Trust by design.

Every tag URL is HMAC-signed per canteen with a 256-bit key, so cloned and tampered bracelets never settle. Staff PINs are bcrypt-hashed. Service-role credentials never leave our edge functions. Top-ups go through tier-1 payment providers — we never see card numbers. Operator KYC is a precondition of accepting balances from the public.

Languages.

English, French, and German interfaces, switchable from Settings. The bracelet itself works at any 3C-enabled canteen worldwide regardless of the diner's language.
