I believe the signature is stored in some kind of algorithmic text format in the database that an active x control; which is embedded in the application, can decipher. It is a leaner way to store the signature rather than converting to an image of some sort. I am not certain if the active x control is visible, or accessible through access/registered on the PC. I will be near a Package Track install tomorrow and will try to look that up in case it can help you out.
