Travelers now have another option for getting through security at the Atlanta airport.

Clear, a biometric identification technology firm that sells memberships granting access to special airport security lines, said it is launching service Wednesday at Hartsfield-Jackson International.

Clear kiosks are at Domestic Terminal South, near the TSA Pre-Check line entrance and near the Delta Air Lines check-in area. Clear will not displace PreCheck lines, but will operate alongside PreCheck.

Clear is partnering with Atlanta-based Delta to launch the service at Delta hubs. The firm is at more than a dozen airports nationally, including Dallas/Fort Worth, Denver, Las Vegas, Miami, Orlando, San Francisco, both Washington, D.C. airports and both Houston airports.

A one-year Clear membership costs $179. That’s significantly more than TSA PreCheck membership for expedited screening, which costs $85 for five years.

Delta is offering discounted Clear memberships to SkyMiles frequent fliers. Clear said new members get a one-month free trial.

Clear said its process is approved by the U.S. Department of Homeland Security.
