I like this idea. Mike Elgan in CofM on the ‘i’ in iPhone and how it will stand for ‘identity.’
Apple loves to solve huge, hitherto unsolved problems. And there is no problem bigger from a lost-opportunity perspective than digital identity.
NFC plus biometric security plus bullet-proof encryption deployed at iPhone-scale adds up to the death of passwords, credit cards, security badges, identity theft and waiting in line.
