Within the next few years, airport face scanning and tightened security will be the norm. A new program, called “biometric entry-exit system,” will work like a super-sophisticated police line-up. It will instantly compare your features with millions of other faces on electronic file, including criminals, terrorists, anarchists, mental cases and other dangerous people.

So, next time you’re in an airport, don’t be surprised if a Sherlock Holmes scan happens to you. Sometime, somewhere, someplace when you least expect it, something gets into your face and says, Smile! You're on Candid Camera!
