As Delta’s press release notes, biometrics are surging in airports across the globe. Travelers hate long lines, invasive scanning, and crowded waiting areas, so Clear, Delta, and other airports have packaged biometric scanning as luxuriant, exclusive, and above all else, extremely convenient. Anyone would be seduced by the opportunity to turn the hours long slog of airport security into something breezy and painless.

But, this veneer of comfort masks that biometrics are a form of surveillance hotly contested by privacy and civil liberties experts. For example, face recognition in airports is consistently less accurate on women and people of color, yet are asymmetrically applied against them as they travel. Clear uses finger and iris data, but Delta was the nation’s first to use face recognition to verify passports, again via autonomized self-service kiosks.

At a time when people should be more wary of biometrics, airports are carefully rebranding surveillance as a luxury item. But, as people become more comfortable with being poked, prodded, fingerprinted, and scanned as they travel, privacy is becoming a fast-evaporating luxury.
