Augme

Nice community-building marketing idea that may be the gentle introduction to 2D codes the West needs. For me though, the real treat is the "Find a reader for your phone" form. Select your make and model and it will list any known compatible reader software and give you links to download them. It's so easy to find at least one reader for your phone. By promoting the reader apps out there and giving people a fun way to use the codes Augme is educating the public about their use and helping open the door for mobile campaigns and creative applications that make use of 2D bar codes.

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.
