Retail Biometric Normalization

Large supermarket chains are rolling out on‑entry biometric scanning—faces, iris/eye data and voiceprints—ostensibly for security, often expanding pilots without clear deletion policies or transparency about storage and law‑enforcement access. These deployments shift ambient biometric capture from optional opt‑in systems to routine commerce infrastructure. — If the retail sector normalizes ambient biometric capture, it will create de facto mass biometric registries with unclear retention, sharing and legal standards, forcing urgent regulatory and privacy responses.
