It will be cool to see how well this actually works. It might actually be a reasonable use for those otherwise meaningless cameras you can't seem to find a phone without these days.
Online grocery store PeaPod.com is working on a clever way for people to shop for groceries at home: everytime you
take something to eat out of your refrigerator or kitchen cabinet, you snap a picture of its barcode with your
Bluetooth-enabled cameraphone, then that info gets beamed back to your computer, where it’s automatically uploaded into
your PeaPod shopping list for reordering.
