I have several thousand files that each have 6-8 signatures each. Our goal is to verify that each spot is signed and that they were signed in the correct order.
3. Is there a pluggin/comcerial product available already that does this task?
1. I don't know of a way with Acrobat. When you export to a CSV file with Acrobat, it doesn't include any information about signature fields.
As you can see there, you can get the name of the person who signed and when they signed, along with a lot of other information.
