Capture signatures Best method

I have created a fillable form, I have a print name field, and now I am planning a signature field as well.

Some users of th form will complete via Browser or download of the form and using Adobe Reader. Some do have signature pads that can be used to capture a signature using a digital pen with the pad.  The signature pads are from Topaz.

I don’t know if there is a better option to capture signatures based on. Does anyone have any suggestions? The simplest way would be the best.
