Inspiration
We wanted to make a QR Code more dense data wise but we didn't want to do it at the expense of readability, fading is extremely common for QR Codes, so we had to be quite careful in making the project.
What it does
With the use of color we were able to store 200% more data in a QR code
How we built it
We started by creating a CQR Writer with JS and Java, to allow for easy implementation in android and web apps.
Challenges we ran into
We ran into a ton of challenges especially with the fading correction, some colors can look like other colors and when converted to CMYK can straight up loose their data.
Accomplishments that we're proud of
We fit 4 bits worth of information in a single "package" as we call it, they are the little dots a qr code is made up of.
What we learned
Color theory is hard.
What's next for CQR (Colored QR Codes
Maybe modifying some open-source reader apps, we can use some work on the encoding of the symbol as well, with more time we could probably get the data density higher.
