Can a QR code be hidden?

Okay, so, can you actually hide a QR code? That's a fun question!

Yeah, you totally can! It's not like making them invisible, more like... camouflage. Think about it: you can blend them into images, right? Like, I saw this cool thing once where someone made a poster for a concert, and the whole background looked like just abstract art, but BAM! Hidden QR code. Sneaky!

The trick, as I understand it, is making visual QR codes that you can customize. You know, use colors that match, design it so it flows with the rest of the picture. That way, it just melts into the background. It's not screaming "SCAN ME!" it's more like... subtly whispering it. And it still works! That's the crazy part.

I mean, it's not perfectly hidden, someone looking closely will probably spot it. But for a quick glance? Most people won't even notice, they'll just see a cool picture. I wonder, though, does it make them harder to scan? Probably a little, huh? Still, pretty neat idea, right? Makes you wonder what else you could hide in plain sight.
