Increasing Biometrics Use on the Horizon

In the coming months, a wave of government initiatives could start making such high-tech methods of identification commonplace -- beginning with the replacement this fall of federal employee IDs. Similar cards are planned for transportation workers, first responders and visitors to the United States. Packed with biometric data such as fingerprints and containing a computer chip with room to expand the amount of information stored, the new IDs represent a potential boon to technology companies eyeing an estimated $8 billion in identity-related contracts.
