The Bone Protector

This web security device for children must get some porn craving kids to drink gallons of milk: age determination on the basis of a bone analysis.

Users simply place a middle finger against a device that attaches to a computer. The device uses ultrasound waves to check more than a dozen biometric attributes, including how much calcium is present (children have less than adults).

Small problem with the device is that it only determines the probability that a user is a child or an adult. Too bad if you are 18/21 and got the bone structure of a 16 year old, and vice versa. Too bad if you got no middle finger, for that matter.
