TRENTON, NJ (NBC News Channel) -- There are fewer smiles to be found inside New Jersey Department of Motor Vehicle offices.
New rules prohibit "big smiles" in driver's license photos. Officials say the new rules are part of an effort to crack down on fraud and identity theft.
New facial recognition software designed to go through photo records to make sure that drivers are who they say they are can be thrown off by exaggerated smiles.
Eyeglasses are also forbidden in the photos.
