The rise of “age-guessing” software: the end of the fake ID, among other things?

Bit of buzz at the moment around the company Face.com, which has developed software that uses facial recognition technology to assign minimum, maximum, and best-guess ages based on your face. Could be handy for stopping underage booze sales, and we know it’s a fun shortcut for tagging people in photos, but those hardly seem like the most lucrative applications. Imagine if cameras that pinpointed your age could customize the ads you see on store display? Scary-cool.

Wonder what else Face.com might have in mind for their tech. Got any suggestions for ’em?
