1

Tray Linking

Link your tray to your identity via face recognition, QR code, or IC card. Simply place the tray on the sensing area to complete linking.

2

Self-Serve

Take only the amount you want at each food station. Electronic scales measure weight in real-time, auto-calculating by the gram.

3

Auto Settlement

After your meal, the total is automatically calculated. Pay only for what you took. No cashier needed — smooth and seamless.

Products

Two key devices that make weight-based checkout possible.

Tray Linking Terminal (tablet + IC card reader + sensing area)

Tray Linking Terminal

A dedicated terminal that links trays to users via face recognition, QR code, or IC card. Authentication status is displayed in real-time on the touchscreen. Simply place the tray on the sensing area (Tray Reading Area) to complete linking and start your meal smoothly.

Weighing Station (electronic scale + food warmer + display panel + sensing area)

Weighing Station

An all-in-one set with high-precision electronic scale, food warmer, and display panel. Weight is measured in real-time as food is served, auto-calculating by the gram. Place your tray on the sensing area to automatically record — only what you take is accurately charged.
