And a patch, this is the one of first woven/embroidered QR patches we know of. We are experimenting with wearable QR codes, this is our first one and it works great!

  1. One idea to help with the scanability of the woven QR code it to use the dense alternate case-insensitive encoding. If you use the limited character set of only capital letters and a few certain punctuation marks the encoder can pack more characters into the code. Luckily URL transport types and hostnames are not case sensitive, so you could encode the url as http://ADAFUI.IT/QR and it would fit into a “Version 1″ code (21×21 pixels) instead of the “Version 2″ (25×25) it currently uses. This would allow either larger pixels and higher ECC, both of which might improve the read rate.

  2. hey @T – we tried a few different types and permutations, this one seems to work the best across all the apps, materials and tests – but we have some more ideas for some fun stuff soon too!
