Give every table an NFC tag and a QR code. Customers order from their phone, waiters get notified instantly, and the kitchen never touches a paper ticket.
The table's NFC tag or QR code opens the live menu — no app, no account.
An alert reaches the waiter's screen instantly; they confirm with the table and send it to the kitchen.
The moment it's ready, the waiter knows and the customer's tracking page updates.
Customer pays the waiter or cashier directly; the cashier confirms and feedback is collected right after.
