The Homeland Security Department would be required to consult with industry executives on biometric identification for airport security under newly proposed legislation.

The bill, which was introduced May 7 by Homeland Security Committee Chairman Rep. Bennie Thompson (D-Miss.), came less than a week after the Transportation Security Administration was to begin tests to screen airport employees at selected airports.

The tests include biometric identification of employees at two airports. Several airport authorities also recently formed a consortium to make plans for biometric ID cards.

Under Thompson's legislation, the goal is to ensure there is a comprehensive plan in place before airports begin using biometric ID systems, Thompson said in a news release.

"This is not about re-inventing the wheel or putting a stop to any good work at TSA -- it is about helping us build upon smart, efficient and effective airport security measures needed to secure Americans and protect a vital industry to our economy and resiliency," he said.

The bill requires that:

- TSA study existing and proposed industry programs for biometric screening at airports.

- TSA study how airports might transition to biometric systems.

- TSA submit to Congress a report on best practices for issuing biometric credentials for airport workers.
