Everything has problems (Score 2, Insightful)

I understand that security needs to be tight when it comes to money, but I think that although this guy brings up some interesting points, I think that this method of purchase is more secure than most of our purchases done today. Cash can be stolen, so can credit cards, and people can forge your checks. So what's the big deal with the capability to duplicated fingerprints. I think it would be much harder to get a clear fingerprint from someone without their knowing than to pickpocket them and steal their wallet. The only problem I can see with this is that you can't just go and have your fingerprints changed (unless you have a lot of money), so this would be more permanent. I think that adding a 6 digit pin would fix this problem.
