QR-coded retail goods

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 can be a package with a number of items, or a unit with weight). There is no product 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 codes!

The outcome:

Manufacturers of cash registers: would be able to design new scanners that are compatible with both old BAR codes and new QR codes. It's a business opportunity.

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 lot of 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 have to update their cash registers with QR-code capable ones.

End consumers: would be able to track their consumption habits by scanning the QR codes into their mobile devices before purchase and at the times of consumption.
