1. Bottle Cap Codes (Implemented in the Cap Factory)
Currently, two primary application methods are used: Single Code (inside the cap) and Double Code (inside and outside the cap). Single code simply generates a QR code inside the cap using laser or inkjet technology. However, with inkjet technology, it is important to ensure ink does not penetrate the beverage to avoid food safety concerns. Double code requires generating distinct QR codes inside and outside the cap using laser or inkjet technology. The internal code typically serves as a promotional code for redemptions or lucky draws, while the external code is used for product information and traceability. After cap production, it's necessary to associate the internal and external codes using code readers.
