Is it possible to have a digital signature field?

is it possible to have a digital signature field of some sort? Is their some way to provide a field where as on a physical form someone would place a signature?

Yes. It is possible to get the signatures from the users who fill the forms by using one of the following widgets.

If you have a DocuSign or Adobe E-sign account, you may also integrate them with your forms.
