Use of QR codes on food packaging in Japan
I think that the use of QR codes on food packaging is an interesting concept with many applications: from getting nutrition information to being able to track down the source of every item in your fridge. If anything, it could serve as an additional medium for broadcasting food contamination alerts.
In terms of gauging the progress of these applications being adopted in the West, I found this exchange quite distressing. Funnily enough, those are from summer 2010. Food producers in Japan have been allowing consumers to check food safety by using QR codes on food packaging since 2004.
