3C Canteen

3C Canteen — Cashless. Connected. Quick. The lunch line, transformed. 3C Canteen replaces cash and ID cards with a single tap. Diners carry an NFC bracelet or a printed QR card; staff tap it on a phone at the till and the meal is paid in under a second. No PIN pad. No coins to count. No queue at the kiosk. Built for schools, universities, corporate canteens, and any food-service operation that runs a fixed roster of customers — 3C Canteen brings the convenience of contactless payment to environments where cards and cash both fall short. Three apps in one. For diners and parents: • Claim a 3C bracelet by tapping it on the back of your phone, or by scanning the QR card. • Top up via Stripe card, MTN Mobile Money, or Orange Money — whatever your canteen accepts. • See real-time balance and transaction history. Set per-bracelet labels like "Sophie's lunch" or "Marc's snack budget". • 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 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 with 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 / check-out, 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're 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. 3C Canteen is published by HandwerkSolutions OÜ, an Estonian company governed by EU GDPR and the Estonian Personal Data Protection Act.

The bracelet itself works on any 3C-enabled canteen worldwide regardless of the diner's language.
