(keitai-l) QP? mobile-camera-readable barcode-type thing

Hello Keitai-L -

Today I was handed a business card from someone in Tokyo with a pixellated
square patch in the corner of the card that I'm told is readable by a mobile
phone camera.  The contact information of the business card is contained in
that barcode-like pattern, they said.  They call it "QP" ?

I can't find much trace of it on the web - I'm not sure that I have my facts
straight.  Any idears here?

Thanks,

Justin
