Mobile authentication of today

I googled the topic of fingerprint authentication for mobile phones and found some blog posts on that subject. This engadget blog post describes the Pantech PG-6200 as a "new handset for the security-conscious Taiwanese citizen who also wants some pretty capable multimedia features in his/her cellphone". Here is another example from Toshiba. In fact, there are 40 mobile phones with integrated fingerprint sensors shipping today. Most are sold in Asia. Biometric cell phones are widely used in Asia for mobile commerce (M-commerce), online banking and for securing the device in the event of loss or theft.
How could we benefit from online identification in the future? Well, a whole lot if you'd ask me. To be Xhausted...
