A group of designers came up with an idea to help those who can't tell if a fruit is rotten, pick the fresh ones.
In supermarkets where loads of veggies is stacked and dumped, freshness may not be a priority. Keeping a track of all that’s been brought in can be time consuming and not all buyers may have a knack for freshness count. The Fresh Code offers a simple solution to this problem; it’s an intelligent barcode with a graph that indicates the freshness level. As time passes by, the graph on the barcode keeps receding, till it finally reaches “0”; indicating that the veggie needs to be dumped and not sold - Yanko Design
If only they have one that also tell you if you are being ripped off by the supermarket. I might actually enjoy shopping then.
