Geist interactive has introduced proSign 1.0 (http://www.geistinteractive.com/proSign), which lets you add signature capture to any FileMaker Pro solution. Signatures can be captured using any touch pad or pen and tablet input device.
ProSign runs on both Mac and PC, and no special hardware is required. Signatures are captured and stored as Base64 encoded data urls which makes them easy to display in web viewers or to embed into HTML email, according to geist interactive founder, Todd Geist.
You can also convert these into PNG files later for storage and display using the free GoSignCompanion plug-in. ProSign requires FileMaker Pro version 9 or greater
ProSign is available by itself for US$239 or bundled with GoSign for FileMaker go for $289. Existing GoSign customers are eligible to get proSign at a special price of $219. Site licenses and demo files are available.
