QR codes

This is the QR-code developed for the BBC  in the UK.  The latest issue of Exporter magazine has a useful article by Anthony Doesburg entitled: "The Viral Potential of QR Code for Product Marketing".   (Issue 15 June Qtr 2010 p.22)  He notes that the winemaker Giesen from Canterbury is about to start using codes on their wine bottles.  The Giesen wine I looked at in the supermarket this week certainly didn't have them yet.

Has anyone had any experience of QR-codes within the exporting sector, or for non-profits?  It would be great to hear from you/
