I agree with Apple turning the iPhone into a universal debit card and Google’s Android supporting Near Field Communication (NFC) but not everything discussed in the article will happen that fast!
Why? Because I strongly believe that before Apple and Google implement a workable biometric ID solutions for cell phones or replace current authentication infrastructure with biometric infrastructure, the authentication will pass through other stages…like, two (or multi)-factor authentication (Yubi-key style touch key, some sort of machine tagging for cell phones) or one-time passwords (sent via out-of-bound channel like SMS or email).
The obvious password replacement is biometric identification — the use of a system capable of recognizing unique physical attributes, such as fingerprints, iris patterns or voices.
Far too many people don’t trust biometrics because it feels like Big Brother technology. But I believe that if the biometric system resides on the user’s cell phone, and is under the user’s control, such technology would be far more acceptable to the public.
Fingerprinting is not very reliable, voice recognition tehnology, in general, is suffering from false-positive and false-negative issues, and iris scanners/sensors are costly.
