iOS QR Code Scanner

The Ready-To-Use UI (RTU UI) is an easy to integrate and highly-customizable high-level UI component that can handle most cases and tasks in barcode scanning. The design and behavior of this component are based on our many years of experience as well as the feedback from our SDK customers.

Although the main idea of the RTU UI is to provide simple-to-integrate and simple-to-configure components, the customizing capabilities are almost infinite and should suit most of your needs. Should you need even more customization options, you can implement custom UI and business logic using our Custom UI Components.

Change the visuals to suit your needs​

In addition to a fresh new design, the RTU UI v.2.0 comes with new configuration options that enable you to quickly adapt its visual appearance:

Palette​
Using the new palette feature, you can change the UI components’ colors to match your brand design.
