Is there an option to add a plug-in for digital signing?

Is there an option to add a plug-in for digital signing? I want to switch over to a paid version of jot form, and I'd like to integrate contract signing into my website.
Thank you,
Gillian

Yes. It is possible to add a signature field to the form. You may consider using one of the widgets from the link below on the form for signing the form.
