Supermarkets face challenge of liquidating the stocks before they shoot the expiry date by promoting these products by offering higher discounts which would need the staff to manually paste the stickers making it time consuming and laborious.

Realizing this problem, students from National Taipei University of Technology developed Barcodiscount which uses color-changing ink technology and displays different discounts as expiration date nears.

This color changing discount was found to reduce the waste by ~33% and also increase the revenue by around 6.3% making it really a win-win to all.

Kudos to 3 students for thinking out of the box on such an Innovative solution tackling food wastage.
