Clear has recently partnered with Delta to help expedite the use of biometrics in certain airports. Thanks to this partnership, travelers will no longer need to show boarding passes at biometric checkpoints. Delta SkyMiles members who are enrolled in Clear, will be able to check in using iris scans or fingerprints as their boarding information will be identified with their biometric IDs and they will not have to show their physical printed boarding passes. This is the latest step in biometric ID scanning and is available in 26 U.S. Airports.
