Encode data in 2D on your T-shirts, business cards and stickers !

Step 1Parts needed

Parts needed
You'll need the following:

Some text to 2D-encode (and worth to decode !).
A PC with a Web browser and Java VM : Windows or Linux doesn't matter for the encoding process.
The decoder applet for your camera-equipped mobile (if you want to decode also, I want).

The text for me will be http://www.instructables.com and http://www.5volt.eu , the latter being the place where I post my projects I can't make an Instructable. Both worth to me to encode and print on stickers, business cards and T-shirts.

The PC can be any, equipped with a web browser and Java.
Jaxo Systems ( http://www.jaxo-systems.com/home ) makes software for image processing also and provide decoding Java applications for mobile phones and PCs to acquire and decode various bar codes (2D included) and free to download.
In their homepage you can encode your text and save the 2D representation as a graphic file ready for print.
You can also download the jar file to execute as a stand alone application.

Use is granted by Jaxo Systems for personal use only, as stated in their homepage.

Below is a roundup of addresses found by readers and posted in comments.
Many of them have downloads for mobile phones, some others have directions for others sites also.
