Ethical Shopping Carts Track Calories, Food Miles

My dad once had a talking Chrysler that would say "a door is ajar" or "fuel is low". When asked why he would buy a car that nags him, he replied "it makes me feel at home." Some may feel that way about the new shopping cart being floated by Electronic Data Systems Corp; it has a bar code scanner and screen that will give information about calories, nutrition, ethical sourcing and food miles, and keep a running total for you.

"Shoppers want bar-code readers on their trolleys [shopping carts] to calculate the nutritional content and tell them when they have blown their calorific budget," said EDS' Sion Roberts, director of consumer industries and retail. ::Scificom and ::computerworld
