1. How to use this Template
Create a QR code on or some other online QR Code Generator
Can be used to encode a url or plain text message
Make sure your message is short enough to fit into a 21x21 QR code. If it isn’t, pick a shorter message or use a url shortener like bit.ly
Use auto generated QR code to update the shading pattern on this template
Click on the desired pixel and set shading to black or no shading
Optional: Design clues in each of the back triangles of the puzzle
Printing this clue
If this clue is printed double sided, the back of the QR code will be divided into 4 triangles that can be cut apart to make a puzzle
The colored outlines around the boxes allow for an easier assembly so that the only challenge is to get the device to scan it.
Using this clue
Since it isn’t a very challenging puzzle (unless the colors are removed), it works well to hide the pieces in different locations so that it is clear that it will be a QR code but it can’t be scanned until all the pieces have been found.
