San Francisco International Airport (SFO) has become one of 15 U.S. airports to implement the new TSA PreCheck Touchless ID system, which uses facial recognition to verify a traveler’s identity. The technology allows enrolled passengers to clear security in seconds by looking into a camera, eliminating the need to present a physical license or boarding pass.
The system works by matching a live photo of the passenger against images already on file with the federal government, such as a passport photo. SFO is the only Bay Area airport currently participating, joining other major hubs like Los Angeles International, Denver International, and Hartsfield-Jackson Atlanta International Airport.
The service is available at no additional cost to existing TSA PreCheck members traveling on American, Delta, United, or Alaska Airlines. Passengers can opt in through their airline’s mobile app by linking their Known Traveler Number and passport information. A digital indicator on their mobile boarding pass will confirm their enrollment. Although travelers are still required to carry a physical ID as a backup, most will be able to proceed through the checkpoint using only the camera scan.
According to the TSA, the images are not used for law enforcement or surveillance and are deleted within 24 hours of the flight’s departure. The agency plans to expand the touchless system to more airports in the coming months as part of a broader effort to modernize and streamline air travel security nationwide.
