Grogs said:I was referring to a different crime actually. If the police find a dead body in my back yard tied up with duct tape and checking my credit card records they found out I bought 36 rolls of duct tape yesterday, I could claim my roommate stole my credit card and thus he's the murderer. Unlikely in the extreme, but it's that one last bit of doubt the police would have to do away with for an iron-tight case.
That's another part of the whole point. This makes it far less likely that the police are going to nab the wrong guy.
As for the security of the biometrics, it seems that whatever type of data, be it the 16 digits of a credit card or a finger print scan ultimately gets digitized and sent off for comparison against the bits in a database somewhere. If a person can get hold of the digitized fingerprint (a local copy stored at the grocery store for example) then it can be spoofed. Maybe some of the math genuises could come up with a way to prevent this, but AFAIK we don't have anything like that right now.
I really don't see how this can possibly be done for an in-store purchase. Presumably you need to actually touch something that will scan your fingerprint and approve you for purchase. How is someone going to use your digitized fingerprint image to fake this system? They would have to touch the scanner to make a purchase, and nothing they do can make their fingerprint look like yours short of cutting off your finger and surgically attaching it to their own hand.
