Delta Air Lines Tries Letting Passengers Use Fingerprints as Boarding Passes

Delta announced this week that travelers who are members of its SkyMiles loyalty program and enrolled in Clear, a third-party biometric screening program, can choose to use their fingerprints as proof of identity at Ronald Reagan Washington National Airport. Still, the introduction of fingerprint scans isn’t without risk. Computers that store personal information about Delta’s customers, including fingerprints, could be hacked. ... “With a password, you can just change it and move on with your life. You can’t do that with fingerprints,” said Nasir Memon, a professor of computer science at New York University’s Tandon School of Engineering.
