Digital Signature field

Such a field type is not currently available. We could make an add-on for you to handle this type of input. You can contact us via https://calderawp.com/contact/ to discuss custom development.

I’d be interested in a digital signature field as well.

It doesn’t integrate with Caldera Forms — yet — but, there is a good plugin for digital signatures you should checkout WP e-Signature https://www.approveme.me/
