How to decode QR codes without a computer

At the 37C3, the 37. Chaos Communication Congress, blinry and I gave a workshop on QR codes and how to decode them without a computer. We talked about their history, dangers, other codes, but the biggest part of the workshop was hands-on: Which parts are there in a QR code? Where and how is the data stored?

As there were so many people interested in the workshop – we even had to move to a bigger stage and still we didn’t have enough space – we published the workshop as a website: qr.blinry.org. Have fun!
