In today’s retail environment, the boundaries between online and offline experiences are increasingly blurred. Mobile applications can bridge this gap by providing interactive tools that connect the physical store with digital personalization. One such solution is an in-app QR code scanner that directs customers to individualized promotions and recommendations based on their unique profile.

By enabling users to scan QR codes placed in physical locations—such as shelves, displays, or posters—brands can drive engagement, gather valuable behavioral data, and deliver a seamless omnichannel experience. Each scan automatically appends the user’s UUID (unique identifier) to the destination link, ensuring that the landing page content is fully personalized to that individual.

This use case demonstrates how to create an interactive in-app campaign featuring a built-in QR scanner that redirects customers to a personalized landing page with AI-driven recommendations. Using a predefined template, the setup process is quick and does not require building the scanner interface from scratch.

You will use a predefined template with the resize option, which appears permanently in the application as a top or bottom bar, providing easy access to the QR code scanner and simplifying its implementation.

The campaign targets users who interact with a brand in physical locations by scanning an in-store QR code to unlock exclusive discounts for the promoted brand and get product suggestions tailored to their preferences. After scanning the code, the users are directed to a landing page, where they will find the personalized recommendations from 3 specific, promoted brands, costing more than 50$.

What is more, you can use this scanner in different scenarios by letting the user scan QR codes in various placements - in stores, on street banners, in magazines etc. Each time, you deliver personalized content and recommendations, avoiding sending the same content to everyone.

What’s next


After launching the campaign, when the user taps the in-app message, the device camera will automatically open and the QR scanning mode will be activated. Once the QR code is successfully scanned, the user will be redirected to the dedicated landing page created for this campaign.

The system will automatically append the user’s UUID to the landing page link, allowing the platform to identify the customer. Based on this unique identifier, the AI engine will generate personalized product recommendations tailored specifically to that individual.

As a result, each user will see a unique, personalized product view on the landing page — no two users will see the same product set.
