Biometric finger scanner can tell how old you are

i-Mature Age Group Recognition

So an Israeli company called i-Mature wants your kids to give them the middle finger. But only so they can scan it to make sure how old they are. They've developed a biometric scanner called the Age Group Recognition Security System that uses ultrasound waves to make more than a dozen different measurements of the bones in your finger, using them to calculate a guess as to how old you are. And of course you know what they want to use it for: to keep kids off of porn sites and out of "adult-only" chat rooms.
