One use that I am thinking about right now is that it would be handy to be able to use a barcode scanner or a link to another app, such as Shopsavvy, to create an inventory of my belongs. This could be used for new purchases by scanning the UPC on the box. This could be used to create a catalog of books if there were a way to get the name of the book and the author from scanning the UPC. (not sure if that is possible) Basically, I was just thinking about how to create a home inventory. I guess right now the best thing is to use the camera feature? but would love to be able to get text information from the bar codes or online qr code links?
