TSA agents could end up being replaced by machines

The Transporation Security Administration is the main reason why so many Americans hate flying. Not only is it annoying to have to strip down at security checkpoints, submit to the occasional patdown, and stand in long lines to verify our identities, but the entire system is inefficient. But what if all of this was done by machines instead of people?

Next to have their jobs automated: airport-security screeners? Aviation and government authorities are starting to use machines in lieu of people to verify the identities of fliers by scanning their faces, irises or fingerprints. Dozens of airports in Europe, Australia and the U.S. already employ such technology so passengers can pass immigration checks without showing identification to, or talking with, a person. Now, several major airports in Europe have started using these automated ID checks at security checkpoints and boarding gates.
