Hi Joe! There is no program available that will scan data from a document into the fields in PAF (or any genealogical program).
You could however, use an OCR program (OmniPAGE as an example) to scan the document. Then using cut and paste, you can then "paste" the relevant details into the fields in PAF, particularly the NOTES section. It's a long laborious process - I know I have done it many times! Other than that you have the task ahead of you of entering the details directly into PAF.
