The Transportation Department is also considering a plan to allow airline passengers who volunteer for background checks to bypass long lines at security checkpoints. The plan hinges on technology to verify a passenger's identity, such as a retinal scan or fingerprint. Airlines and airports are pushing for tamperproof "smart cards" that passengers would show at the screening area.
All of this is good. While flying has returned to near normal, many people are still afraid to fly and concerned about security. The smart cards and a uniform screen process presided over by the feds would help restore confidence.
