Denver is the 14th U.S. airport to offer TSA PreCheck Touchless ID lanes.
Touchless lanes are now available at the airport's East and West security checkpoints for PreCheck flyers on Alaska, American, Delta and United who have opted in ahead of time with their airline.
In Touchless ID lanes, flyers are able to go hands-free through the checkpoint, pausing only briefly for a photo that is biometrically verified against passport or driver's license images.
The TSA says Touchless ID screening takes an average of eight seconds, compared with 18 to 20 seconds in standard PreCheck lanes, where photos are still verified manually against a physical or digital ID.
The other airports that have Touchless ID are Atlanta, Dallas-Fort Worth, Detroit, Las Vegas, Los Angeles, Newark, New York JFK, New York LaGuardia, Phoenix, Salt Lake City, Seattle, San Francisco and Washington Reagan National.
