GeniCan is a small device that attaches to your trash can. As you throw something out, use GeniCan to scan the barcode on the item and it'll be added to your shopping list. If the item doesn't have a barcode, hold it in front of the Genican and say what it is — it'll still be added to your list! Using this device is one way to make sure you never forget what you need from the grocery store.
