iCandy is a desktop scanning tool for QR Codes. You can generate QR codes on some websites, such as this one. Google has an open source API for reading QR codes. BeeTagg is a reader application for your cell phone (many models accepted).

Using Australian handsets they become hard to read over 25 characters of text in a QR code because they become so complex.  Even under 25 characters the codes shouldn’t be smaller than 2.2cm in width/height otherwise the handsets will have issues with it.

In Australia they sent out 6000 invitations of a party to magazine subscriptions. On this invitation was information on how to obtain a QR code reader on their cell phone, and a QR code with more details about the event. There was also wording that said, “This is a QR Code. It is very popular in Japan and you should get a reader.” 400 people scanned that QR code.
