    Default QRCode App

    QRCode App


    Stemming from Vinylfox's (here) idea, I decided to embark on my own with a much needed feature.



    I wanted to have offline support and JavaScript can't really get source of a file, I needed to throw Google services out. I found a PHP library that does it so you have to run it on a server with PHP, no biggie tho. The PHP creates a PNG file containing a QRCode, then base64's the image and returns that string with some other parameters. Sencha Touch then takes that array and put's it in an offline Store.

    Demo: http://www.simoens.org/Sencha-Projects/QRCode/
    Git: https://github.com/mitchellsimoens/QRCode

    Updated code to use JavaScript to generate QR Code using Canvas. VinylFox found the JS code to do this so hats off to him but I beat him to it!

    Git and online Demo has been updated!

    Just tried the demo, created a couple of QRCodes and read them perfectly with the iPhone RedLaser app. Just phenomenal work Mitchell! Very, very impressive :-)
