QR codes are beneficial if used for ordering and transactions. A visitor takes a seat at the table and scans a QR code to access the digital menu. Depending on the system, the QR code might be unique to the table or need the visitor to provide their exact table number. The customer may explore the menu, add things to their cart, and deliver their order directly to the kitchen. When visitors are ready to depart, they have to pay for their food and leave!
