That's something that I've never gone looking for since the subject has never come up with the stuff that I do, but it seems to me that a signature pad is merely a small-format drawing tablet and that's a very old technology. (There was a drawing tablet available for the Commodore 64.) So perhaps instead of looking for a "signature pad" what you really want is just a small drawing tablet like a Wacom for which linux drivers come built-in with Centos. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
