Biometrics for borders now ?
Yeah, that'll be really useful. Not.
The only solution to immigration issues is first, enforcing existing laws - which are never properly enforced due to political pussy-footing and lack of manpower, and second, putting enough manpower into the effort to make it work.
No amount of technology is going to miraculously solve illegal immigration. Footwork and experience are the only things that will.
Plus, as far as biometrics go, I don't see why I should give up all my details to some unsecure, unguaranteed foreign entity just because I decide to go there and spend part of my holidays.
Any country that requires my DNA before letting me in is going on my personal black list and will be removed from possible holiday destinations. They have no right or use to profile me, and I resent in advance any hassle that will arise because there is a mistake in their bloody database.
And mistakes there will be, given the track record of just about any government security process or IT project.
Why should my life be ruined because some stupid git mistakenly decided that my DNA somewhere was a security threat ? What defense do I have in a Gitmo cell ?
I frankly see no benefit to innocent people, and hardly a threat to terrorists.
Name me one terrorist that got caught because of his mobile phone.
