Among many things which I'd love to comment (I can't get rid of the feeling that author is media-obsessed person and spends too much time online) this one is interesting:
How about walking around with your cellphone with dangling fingerprint device attached?What about biometrics? After watching lots of movies, many of us would like to think that a fingerprint reader or iris scanner could be what passwords used to be: a single-factor solution, an instant verification. But they both have two inherent problems. First, the infrastructure to support them doesn’t exist, a chicken-or-egg issue that almost always spells death for a new technology. Because fingerprint readers and iris scanners are expensive and buggy, no one uses them, and because no one uses them, they never become cheaper or better.
