The program uses biometric face matching to eliminate the need for manual ID checks at checkpoints like bag drop and security.

The program is eligible for customers who have a TSA PreCheck membership, have a free SkyMiles membership, and have the Fly Delta app. They must also have their passport information and a Known Traveler Number stored in their Delta profile.

Eligible customers get an automatic notification in the app when traveling from an airport with the digital ID program. Once they opt in, the Delta Digital ID becomes a part of their SkyMiles profile. Customers can opt out at any time and Delta does not store any biometric data, the announcement notes. The face biometrics capability at the original Delta Digital ID locations is provided by Pangiam.
