A QR code dedicated to ordering at the table saves time during service on order-taking and payment, and therefore boosts restaurant sales by increasing table turnover.
It frees your waiters from time-consuming tasks (distributing the menu, taking orders one by one, dividing up the bill between each customer), enabling them to concentrate on higher value-added tasks, such as reception, service, or managing the restaurant during rush hour.
It's also a more hygienic solution in times of epidemics (covid, flu, etc.), since no paper menus or species circulate from hand to hand.
