In June, pas­sen­gers jaunt­ing off to Aruba from Bos­ton with JetBlue could keep their board­ing passes and pass­ports tucked away—that’s be­cause the car­rier started ac­cept­ing fly­ers’ faces as ID. A cam­era at the gate snaps a photo of each par­tic­i­pat­ing trav­eler, and then a U.S. Cus­toms and Border Pro­tec­tion al­go­rithm matches it against a photo of the trav­eler’s vis­age on file, giv­ing each voy­ager the green light (or not).
