Frequently Asked Questions

Employees use their smartphone camera to complete a 30-second facial scan during enrollment or wellness events. Circadify's rPPG technology extracts cardiovascular signals from subtle skin color changes, producing structured health data without wearables or clinical visits. The process works on any modern smartphone with a front-facing camera.

UseHealthScan scales from small employer groups of 50 employees to enterprise deployments of 10,000 or more. Because screening happens on individual devices rather than at centralized stations, there are no scheduling bottlenecks or capacity limits. Multiple groups can screen simultaneously across different locations.

Participants receive a link or in-app prompt within your enrollment portal. They face their phone camera for approximately 30 seconds while the rPPG engine captures biometric signals. No app download is required for web-based deployments, and the entire process completes without assistance from onsite staff or technical support.

Each screening captures heart rate, heart rate variability, stress index, and blood oxygen estimation. Results are delivered as structured JSON via REST API to your benefits administration platform, underwriting tools, or analytics dashboard. Group-level aggregations provide population health profiles alongside individual records.

UseHealthScan connects via REST API or embeddable SDK components that fit inside existing enrollment portals and benefits apps. TPAs and carriers configure data field mappings, branding, and screening parameters during onboarding. Most integrations complete within a few days of technical setup.

All biometric computation runs locally on the participant's smartphone. Raw facial video never leaves the device and is discarded after processing. Only structured health metrics are transmitted to your systems, which reduces HIPAA scope and simplifies Business Associate Agreement requirements for carriers and TPAs handling the data downstream.
