Clear vs. TSA PreCheck: What's better for price and privacy?

Compared to other forms of data collection, biometrics such as facial, iris or thumbprint scans have greater potential for invasive surveillance or discrimination, privacy advocates say. Facial recognition, for instance, makes it difficult to protect your privacy in public spaces -- law enforcement has already used it to identify protesters such as one man accused of assaulting a police officer during a racial justice demonstration in 2020. At least three Black men in the U.S. have filed lawsuits alleging wrongful arrests due to faulty facial recognition.
