Which Toshiba Satellite models include fingerprint...

Question

Which Model #'s of the Toshiba Satellite Laptop with Intel Centrino Processor Technology come with the Fingerprint Scanner and Face-recognition Technology? On all the websites I have visited(including BestBuy.com and Toshiba.com) it says that the fingerprint scanner and face-recognition software are "Only available on certain models" and I was wondering which models they are referring to. If you could help me it would be great, I cant find the answer ANYWHERE!!!
