Jaxo: nice barcode generator

Very cool online bar code generator that lets you create QR-codes, Datamatrix, Aztec and PDF 417. You can switch between codes to compare them and technical information about the code is also displayed. There are even some simple drawing tools to let you customize you code with color.

You can try it out online or download a standalone Java application. They also make a reader for phones, but I prefer i-nigma and Kaywa over this one. Still, the generator apps are definitely worth a look.

Moji-Q Maker

All About Mobile Life has alerted me to Moji-Q Maker. It lets you make custom-colored QR-codes with text embedded in them. Very cool.

Update

Actually, my AU keitai does not seem to recognize the meta-data in the code. It recognizes the URL, but appends two semi-colons to the end of the URL, which gets a blogger 404. If I could encode a URL only without the title, etc. then it would work perfectly.

QR-code Extensions For Firefox

Here's a couple handy extensions to view a QR-code for any URL with Firefox.

• Mobile Barcoder: Pops-up a tooltip-style window with the QR-Code for the page you are currently viewing.
• QR Code: Uses Javascript to generate a QR-code with CSS.

You can also download some interesting QR-code Javascript tools and libs at D-PROJECT.
