No Smiling at the New Jersey DMV

It messes with their facial recognition software

With its infamous long lines, going to the Department of Motor Vehicles to get your license is usually nothing to smile about. These days, it's a mandatory no-big-smiles policy in New Jersey, one of a growing list of states that tell drivers drivers to keep a poker face in their license photos.

Since February, New Jersey motorists have had to maintain neutral expressions on their faces for photographs because of new face-recognition software. Exaggerated facial expressions, like smiling widely, can confuse this software, which is intended to catch fraud, the Philadelphia Daily News reported.
