QR / AR to open URL

Hi does any body know if this is possible. We want a custom marker ( so like an AR Marker) to be scanned so that it opens a URL ( so like a QR code).

So the problem is that we want a mixture of the two behaviours, it can't look like a QR code but it must open a URL as we don't want any AR 3D imposed on the marker.

Can anyone help?

Thanks in advance.
