Difficulty Reading Small QR Codes in Vuforia Studio – Any Reliable Solutions?

Hi everyone,

I'm currently working on a project in Vuforia Studio that involves scanning QR codes using the built-in QR code widget. While it works in general, we've encountered a major usability issue:

📌 Very small QR codes are extremely difficult to detect.
In many cases, we have to hold the iPhone extremely close and still wait a few seconds until the scanner finally picks it up — and sometimes it doesn’t work at all unless the QR is large and isolated.

We've also experimented with custom solutions using JavaScript libraries like jsQR and zxing-js, but on iPhones in particular, either the live camera feed doesn’t render properly, or the QR is only readable when it's clearly focused and takes up most of the image.

🔍 What we’re looking for:

• Any way to enhance the QR detection accuracy for smaller codes?

• Can we tune or replace the Vuforia Studio QR widget’s behavior or resolution?

• Any suggested workflow or library that has worked reliably on iOS devices?

This is important for our production process — we’d really appreciate any insights, experience, or recommendations!

Thanks in advance 🙏
