K2C eSignature enables the use of SharePoint to electronically sign any document or record in compliance with US 21 CFR part 11, European Annex 11 or other similar regulations. After the installation, a new workflow action “eSignature” is available both in SharePoint Designer workflows (both 2010 workflows or 2013, based on workflow Manager) or Nintex workflow, if you are using this additional workflow tool. This action can be added at any step of the workflow in order to collect one or more user signatures without the need of any custom development or coding knowledge.
