This blog is about QR codes and their potential. The fact that you can put them on any real object and by a single click you can see the reflection of that object in the digital realm makes them a real bridge between these worlds. They are the gate that passengers to the digital world must pass through. As such they deserve a proper attention; they should be treated as valuables keys, the more you know them the more doors they will open.

    Do you know how to make qr codes with circles instead of squares?

    • Atticus,

      Thanks for your question. I think there is a way achieving this with Photoshop. Create a round hole in a size of a module (with white background) as a new pattern and then fill a new empty layer above the QR code with this pattern. I will check this more deeply and write about this in my next post.
