How to capture human signature

Many applications ask their users to accept an agreement, but I can't think of one I've used that's asked me for my actual signature.

Is there a good reason that your users aren't able to accept yr agreement in the usual way? (via a check box or by hitting a button marked 'I accept'?)

• Why is a graphical representation of the users signature required?
• It's difficult to write using a finger, and it's even more difficult to write (using a finger) on a smart phone screen.

There are also privacy concerns relating to obtaining a graphical representation of a user's signature. Once obtained, I have no idea what your company will do with my signature. A signature is a valuable piece of personal information, which could ultimately be used for identity theft.
