Freshness Bar Code

Designers Sisi Yuan, Yiwu Qiu, Lei Zhao, Qiulei Huang, Lijun Zhang, and Weihang Shu have come up with a clever way to determine the freshness of veggies in your supermarket. When loads of vegetables are dropped off in the produce section of a market, most of the time, there are so many to keep track of, the priority of the freshness of the produce may drop as the amount of produce increases. The idea behind this barcode is to easily determine the freshness of the product by the amount of barcode left.
