Scent Biometric
Here’s a new biometric
Recognizable body odor patterns remain constant enough over time to allow people to be identified with an accuracy rate of 85 percent.
Not yet good enough for most applications, but presumably this kind of thing can only get more accurate.
EDITED TO ADD (3/14): The Stasi used to preserve individual odor samples for tracking.

Isn’t it exactly the kind of element that can be stolen from someone to impersonate him ?
If it is used in ‘airports, border checkpoints, …’, we may have to worry about it.
