That is more or less the idea behind this scheme isn't it? But instead
of just digitizing the final form of the sig/doodle you capture the
data as it's being signed: pressure, speed, pauses etc. The dynamic
data for a forger would be very different from that of the genuine
card-holder. And since you no longer need a visual check, you don't
need a sig on the back of the card, so a forger would have to work
harder to get a sig to copy from.
