The keitais here in Japan can also scan QR codes that are displayed on
screen. For example a website can have a PNG/GIF of a QR code, and the
mobiles can scan them to grab a URL. A possible reason to do this is
to allow a user to connect to a mobile version of the site, or perhaps
some special content like a coupon/special weapons for a game.
(You can track useage this way too if you have a web app backend that
collects meta data such as user-agent.)
I'm not a DoCoMo user so I'm not sure about this, but another useage
is that the DoCoMo keitai devices display a QR Code so you can pay
your bill at the convenience stores. I think Gehard mentioned this
before ...
