pretty lame if the card can just say "yes" no matter what PIN is entered.
Away from being a proprietary tech, I'm not sure why fingerprinting the magnetic stripe never took off. It seems so much simpler, and if you cannot rearrange iron at the molecular level impossible to replicate.
Probably it's lack of infrastructure buy-in. And personally, I find the misuse of the word biometric in the white paper off-putting, along with the lack of detail on the basis for the technique. The fingerprint is somehow related to the magnetic particle distribution--how stable is it against weak magnetic fields, or against heat?
If you really can reliably get magnetic signatures, it would be really hard to clone cards.
Edit: the particles won't really change, but their magnetic states feasibly could
