Shopping cart handle that urges shoppers to buy local
The shopping trolley handle will use LED's to let shoppers keep track of each item's food miles.
The handle mounted device will be able to scan a product's barcode and determine its food miles, or how far it has traveled to reach the store. A series of LEDs will light up in relationship to how many food miles each item costs, with a larger number of lights indicating more miles. The handle can also be calibrated to measure factors such as fat, salt, and seasonality.
