I'm using a Drupal 7 site to allow users to record their time spent on various projects. The auditors need these forms to be signed periodically and I'm looking for a module that will let me assemble the data into a PDF document that includes a digital signature field. Does anyone know a module that can do this? I could create the forms with signature fields in Acrobat and use the 'Fill PDF' module to populate the form, perhaps. Are there any other digital signature approaches out there?
Many thanks, Dave
