With all the new *Pad style devices coming out now, I wanted to be able to get signoff by customers on the spot using a signature for quotes, jobs etc in our drupal based ERP system.
This module facilitates that by allowing creation of a CCK field which accepts input via mouse, finger, stylus or anything that can draw on the screen.
You can grab the cck module here:
http://drupal.org/project/signhere
or try it out for yourself here:
http://singularo.com/node/add/sign-here
(Note, all sign-here nodes will be periodically deleted, and are not listed anywhere to deter spammers).
The jquery code part of this module was taken from http://www.crowdsavings.com/open-source/drawbox with a couple of small changes
