How would you like it if grocery carts had touch screens and barcode scanners that you could use to get nutritional info and environmental impact info from about various foods? The Technology Services Company, EDS, outlined in a recent paper that grocery carts with computer screens would be a practical and cost-effective solution to consumers who like knowing about the foods they consume— even though most said they preferred reading labels directly from the box. Considering the fact that people steal shopping carts minus any high tech trinkets, I can only imagine how crazy thieves would go over these! What do you think about high tech grocery carts? Useful or something you think we can wait for?
