Yet, some experts have privacy concerns. Albert Cahn, the founder of the Surveillance Technology Oversight Project, expressed doubts to Bloomberg about the balance between the convenience of biometric services and the amount of personal data they collect. He questioned why it’s better to give private companies government IDs and biometric data when customers could just use their physical IDs for transactions. Evan Greer, a director at the digital privacy group Fight for the Future, told CNBC that people should be cautious about giving their data to private companies. He highlighted tech companies’ poor history of protecting personal information.
