Missouri's Biometric Information Privacy Act imposes obligations on private entities that collect, possess, or use biometric identifiers or biometric information. Private entities must obtain written informed consent before collecting biometric data, develop publicly available retention and destruction policies, and may not sell, lease, or trade biometric data. The Act prohibits conditioning goods or services on biometric data collection unless strictly necessary and prohibits retaliatory pricing against individuals exercising their rights. Enforcement is exclusively through a private right of action, with liquidated damages of $1,000 per negligent violation or $5,000 per intentional/reckless violation, plus mandatory attorney's fees. The Act exempts government agencies, HIPAA-covered entities (for HIPAA-governed data), financial institutions subject to GLBA, and government contractors acting on behalf of government.
