Anyone having read George Orwell's 1984 knows who Big Brother is. Well, it seems that the future (or is it the past, 'cause it's not 1984 anymore) is now. The brain of Big Brother in the form of personal biometric data is going to be stored in a massive database. Then, the plans are to have the contents of the database available to local, national, and foreign law enforcement officers, as well as your employers (but only if they ask). Now, Big Brother can't always be watching unless he knows who he's watching, right? So, get ready for instant screening and location determination as the database eventually becomes available to all municipal scanning devices. Cameras, scanners, and fingerprint accepters will all work together so you will never be lost.
And when they say "You aren't in the system", they will soon mean it literally.
