Understand, but I was replying to Pballer110 post indicating that it can't be done or doesn't work vey well. I have no idea what App for you to use but there is no hardware limitation preventing barcode reading because it works quite well in GroceryIQ.
The only 2 cavets I see are the awkward holding/lining up of a "large barcode scanner" and no flash requiring sufficient ambient light.
Here is a site/search that may have what you are looking for. You'll need to look through.
