QR-coded retail goods
Replace BAR codes with QR codes, and conveniently have product names, nutrition data, and other product metadata at the scanning points.
Ever wanted to keep track of what you are consuming? In current system,
supermarkets and stores don't have unique naming of their products, each
store has the duty to enter the product
names. The producers only provide the unique code of the trade item (which
be a package with a number
of items, or a unit with weight). There is no
quality information on it: neither the expiry date, nor the ingredients, nor the
mass of each unit within the package.
So, the idea is to replace the uninformative BAR codes entirely with QR
Manufacturers of cash registers: would be able to design new scanners that
compatible with both old BAR codes and new QR codes. It's a business
Producers of goods: would be required to include the descriptions (like nutrition
data) of their products not just in small letters on the package, but also include
that information in a QR code on the package. (Yes, QR code can include a
text, and most cell phones can read them.)
Retailers: would not have to care about naming of the products, as the naming
would already be provided by the manufacturers. However, retailers would
to update their cash registers with QR-code capable ones.
End consumers: would be able to track their consumption habits by scanning
QR codes into their mobile devices before purchase and at the times of

More for the legibility issue than tracking. [AusCan531, Jan 18 2013]
||Being able to read the fine print on the label, without actually reading anything on the label than the QR code, could be very good. The phone, of course, would present that text in a nice large font...
