Iowa SSB 3085 imposes obligations on private entities (any nongovernmental entity or group) that possess, collect, or obtain biometric data — defined as information about or based on an individual's biometric identifier (retina, iris, fingerprint, voice, hand, facial geometry, or other qualifying physical feature). Private entities must develop and publicly post a written retention and destruction policy, provide written notice to individuals before collecting their biometric data (including the purpose and retention period), refrain from selling or profiting from biometric data, and protect biometric data using industry-standard security methods. The bill exempts employers using employee biometric data solely within the scope of employment and government contractors acting in their governmental capacity. Enforcement is exclusively through DIAL, with escalating civil penalties and a 30-day cure period for first-time violations. No private right of action is created.
