Fishy QR Codes

Fish-media-qr-1
Fish-media-qr-2

After seeing a post by Terence Eden I was inspired to test out the areas of a QR code that could be blanked off and still work.

I moved a white box around on screen while scanning a QR code with the RedLaser iPhone app and was surprised to see the amount of error correction present in the code. So I created a couple versions of a code with a simple link to Fish Media to test if they still work.

I’m unsure how versatile these will be with other readers and devices (perhaps you could let me know in the comments below?) but I have printed this code out fairly small and it still scans with the iPhone.

Putting these onto MOO stickers could be a realy good idea!

Terence speaks of integrating image creation into his QR code API which could automatically be linked to the final destination. Read his brief post here: QRpedia and Images and his more comprehensive ‘Hiding Space Invaders In QR Codes‘.

    Nice find! I wasn’t aware of this in-built error correction within QR codes. This opens up some nice possibilities. I particularly like the example given by Terence Eden featuring Che.BTW, I tried your code on my using QR Droid Private and Google Goggles on my Desire Z and they worked fine.

    @MPBroadhurst thanks for testing. Would you be kind enough to test my personal one here: http://richard.mackney.com/richard-mackney it should save the contact details to your phone rather than just shoot you off to a URL?
