So I'm working on a random project that involves people scanning in glyphs and piecing together words. It's being done by taking a QR code that links to to a conversion table and in the middle of the QR, a specific glyph is placed. These are then pasted in locations where they can be found in linear series (like bus stops or train stations).
This is what one of the prints looks like.

Scan it with your phone. More than likely you won't be able to scan it at all. This is the problem I have run into with some of the glyphs. They make the QR code unreadable.
Take the above image and in your editor of your choice, cut the glyph out so there's nothing left but a white box int he middle of the QR code. Your phone should now easily read it.
I need to figure out how to fix this problem.
Cut the glyph out?
I tried roughing up the edges and making the glyph slightly smaller. I think the main problem with the glyph is that it looks too square so QR scanners try to use it.

This version seems to have better readability.
I have no idea how these work, could you make the glyph a different colour?

I know it's about images but maybe you can adjust your QR code so that you can use this method

Yeah, honestly neither do I I just messed with it until I started to see results. I did try some color changes before I opted to remake the glyph. Color seemed to have nothing to do with it. I still maintain that the hard edges in the glyph, presented with their proximity (especially the bottom) to the QR code, made the QR scanner unable to differentiate the pieces.

That would work tons better because QR codes do not detect colors and some levels of transparency.
Problem however is that this needs to be scannable at distances over four meters away and my laser printer is black and white only.
Nice idea you've got there.
