I was wondering if it's possible to sign a PDF's signature field in Adobe Acrobat Pro DC (or any app, for that matter) using the Surface Pro 3 and its pen. I don't mean just annotating my signature; I mean a digital signature field. Right now, we are using an ePad LS with their IntegriSign software which includes an Acrobat plug-in for signing signature fields. I was hoping to eventually replace the ePad with Surface Pro 3s, but I can't seem to find a way to sign those signature fields. I can annotate on the pdf, but there are differences in that vs. a digital signature field. Does anyone have a way to sign a signature field using the Surface Pro 3 (and pen)?
