BLE and RFID-based Quality Control and Inspection Tracking System

GAO’s BLE and RFID-based Quality Control and Inspection Tracking System delivers end-to-end visibility into product inspection workflows and defect management. By deploying RFID-only configurations, facilities gain rapid identification and batch verification at inspection stations. BLE-only deployments continuously monitor inspector movements, workstation dwell times, and environmental conditions, offering real-time telemetry for compliance and workflow optimization. Hybrid BLE+RFID implementations combine high-accuracy identification with continuous location and status monitoring, ideal for large manufacturing campuses or laboratories requiring precise quality traceability. GAO leverages advanced tag encoding, geofencing, and event-driven alerts to reduce missed inspections, prevent unauthorized handling of defective parts, and streamline reporting for regulatory audits. With four decades of R&D, GAO provides secure, scalable solutions backed by expert remote and onsite support across U.S. and Canadian manufacturing, aerospace, electronics, and pharmaceutical operations.
