From Toucan Multimedia:
WebPen allows your Web site users to sign documents, forms, and agreements online using the mouse as a pen. Now legal documents and agreements can be displayed online and signed instantly right on your website using the mouse or touchpad as a pen. WebPen eliminates the traditional hassle of downloading, printing, signing, and faxing. Making the sign up process easy avoids lost sales. The signed document is instantly redisplayed to the signer with the signature in place and a copy of the signed document is stored on your server in PDF and in HTML format. WebPen is simple to install, requiring only PHP5+ with bundled GD library, something that most hosts have. It can be incorporated into your existing online documents by the addition of just a line of code to the web page that displays the document. WebPen works with any type of web page extension that can display html code, including .HTM .PHP .ASP .JSP. WebPen uses a new SVG/VML signing engine that runs natively in the browser without the need for java, flash, or other add-ons. It is cross-browser compatible. It loads much faster and has improved graphics. WebPen now has a feature to automatically email the signed PDF documents to the address of your choice.
