QR Fold In

This puzzle presents the players with a piece of paper with pieces of QR code printed on it. The codes cannot be properly scanned on the flat paper.

The trick is to fold the paper to bring the pieces of QR code together. I suggest using a simple fold reminiscent of Mad Fold-Ins (also known as an origami pleat fold).

Creating a fold-in image is not difficult. Simply cut the image in half and separate the two pieces by some distance perpendicular to the cut.

The folds have to be pretty precise to be properly scanned. To help, you can provide a little overlap in the QR pieces and guiding lines on where to fold and align the two pieces.

Figuring out and doing one fold is pretty easy. If you want to add an extra challenge, you can make a second fold in a different direction. This can be done by cutting the image for a fold in one direction, and then treating the entire result as an image and cut in a different direction. (Note that the players will have to fold in the opposite order you cut the images to create it.)

Here is an example that requires a horizontal fold and then a little more tricky diagonal fold.
