supports two types of Digital Signatures. No special hardware is required. All you need is a smartphone or a computer with a browser that supports HTML5. 

1. Signed Sections - Users authenticated to the  server, or in some cases by email, can digitally sign a section in a form/workflow, lock it down and prevent tampering with the data. Signed Sections can display a text rendering of the user's name (user credentials), a previously uploaded signature image, or a signature drawn with mouse/touchscreen.  A A signed section creates a digital signature over the contents of the section, and if set to Wet Signature type, also captures a handwritten signature image. If legally binding signatures and/or authentication are required, Signed Sections should be used.
   
   
2.  Signature Control-  also offers a Signature control that allows any user, including anonymous users, to sign electronically using either a track pad/mouse, stylus or a touch screen in use mode. Both authenticated and non-authenticated users may sign a form using a Signature control from the palette. The signature control only captures a handwritten signature image. It does not create a digital signature.
