Unity place anchor with qr support

I have a large map that I designed using Ar. I want to pin this map with qr. But when I lose the camera QR (for example, when I move the camera closer to the map), it disappears on my map.

Is there a solution to this?

Thank you for your answers.

How did you set it up?
ARF doesn’t have qr code scanning by itself.

If you are using AR Foundation image tracking, you should create an anchor at the position of the image once its been detected, then parent your content to the anchor. Anchor positions are more reliable than image positions over a long duration of time, especially if the image is expected to go out of frame.
