Does anyone know of an ap for storing documents by taking a picture of them and then putting them in separate folders. For example, taking a picture of your gas receipts creating a pdf and then storing the individual doucments in a sepated folder. The "real" document imaging programs do input via a special scanner but I wonder if the ipad can do it via the camera. My son says he can take an image of a business receipt and e-mail it to his accountant. Thanks. Fred M.
