I've often wondered about the electronic signature pads for credit card purchases. Once they have a copy of my signature they can put it on anything. Why would such a signature have any value whatsoever?

The piece of Windows they had did not include drivers. It says:

Much of the code in Linux, for instance, is drivers.
