Digital receipt collection created by Paperless, a program used to organize electronic copies of receipts and other documents; stores scanned images of paper receipts, as well as the transaction information; used for archiving personal financial records.

Paperless can sort the receipt images by date and other metadata. The program also uses Mariner's optical character recognition (OCR) technology to identify receipt text such as the price, payment method, and merchant. Users can then sort and search receipts using this information in the software. NOTE: Paperless also stores digital document libraries in .DWLIBRARY files.
