biometric technology

Everyone knows the headache of waiting on line at the DMV to get a new driver's license. Now imagine repeating that process 1.2 billion times. Thanks to a new ID program, that's exactly what the government of India will soon experience.

The Indian government has just announced a plan to furnish every member of the country's immense citizenry with state-of-the-art biometric identification cards. The cards will carry retina and fingerprint data and credit and criminal histories, and will be linked to a central online database.

Armed with $2 million in federal grants, researchers at the New Jersey Institute of Technology (NJIT) are close to perfecting the first commercially viable "smart gun." The prototype pistol, unveiled last month, is designed to recognize specific people's grips. When seized by an unauthorized hand-say, that of a child or a criminal-the gun locks its shooting mechanism.
