We are working on a prototype which will help you have a full controll over the food in your households. The solution consists of two parts:
1) A mobile sized sensor mounted into your fridge which has a barcode scanner on it will allow you to easilly scan the product you bought , within seconds.
2) A mobile and web application that will let you see the food you have in your fridge together with all the nutrition facts and approximate expiration date. When the food will be nearing it's expiration date the application will send you push notification with recipe suggestions.
