This is probably the only useful tool against illegal immigration, The problem they had with deporting immigrants is that they would go to another country and get another identity and come back again. The eBorders uses biometrics and they are a little harder to fake
(Note in China some women were arrested for using fake latex fingerprints, apparently there's a hugh black market for them in China and there fingerprint database is roughly 104million)
Whats actually happening is that there is a mini arms race with biometrics where every country is tryng to collect as much as possible and the UK has managed to cock it up but still want in so they are deciding to piss away more money but they keep using prehistoric civil servants who are still amazed that PCs no longer come with floppy drives and the only way to run an IT project is through the "Tradition Life Cycle" WTF?!??!!
