I integrated the ScripTouch signature pad from ScripTel (https://scriptel.com) into a 4D application. I didn’t bother with live signature preview in 4D, but instead just integrated with the java app they supply. For 4D integration I launched the java app with parameters detailing what kind of signature image to save using LAUNCH EXTERNAL PROCESS, and picked up the image afterward. The ScripTel also integrates with Adobe Reader for cryptographically signing PDF documents, if that’s necessary. I used 4D to create a PDF, launch Adobe Reader with that PDF, monitor the file for an appropriate number of changes (depending on how many signatures I needed), and email the signed PDF to the appropriate recipients. The signature pads have turned out to be relatively fragile in a traveling salesman environment. They are also extremely sensitive to USB power. I never used the Topaz signature pads so I’m not sure how they or the software compare.
