QR code mobile ordering is a system in which customers scan a QR code placed on a restaurant table or at the storefront with a smartphone and complete everything from browsing the menu to ordering / payment in one continuous flow.
The basic setup of the system is a mechanism in which a unique QR code is placed on each table, and scanning it opens an order page linked to the table number. Users can browse the menu in a browser, add items to the cart, and complete payment without installing an app. The store receives orders in real time and shows them on a kitchen display.
The more data a QR code stores, the more modules (black and white dots) it needs and the larger the code becomes (explanation on DENSO WAVE's official QR code website / as of October 2026). Short URLs are used to reduce the number of characters in the URL placed in a QR code. In addition, using the dynamic redirect feature of a short URL makes it possible to change the URL of the menu page without reprinting the QR code itself. When switching to a seasonal menu or migrating systems, the cost of replacing physical QR codes is eliminated.
In terms of hygiene, sharing menu books is no longer necessary, and in terms of labor costs, the order-taking work of floor staff is reduced. Some systems can also display the menu in multiple languages. On the other hand, supporting elderly customers and customers unfamiliar with smartphones, preparing the network environment, and securing alternative means in case of system failures are challenges.
