SDG Systems’ TallyFlow Asset Tracking System is a cloud-based platform (with optional local/onsite support) for tracking, locating, and managing physical assets, tools, inventory, containers, and work-in-process using RFID (UHF/NFC), barcodes, sensors, and photos. It can deliver real-time or near-real-time visibility via strategically placed RFID antennas/readers, “read zones,” and mobile devices; users tag items, define zones, and then the system logs when items pass through, where they are, and when, enabling workflows such as check-in/check-out, inventory audits, and tracking of work-in-process in manufacturing. It supports features like timestamps, location searches, defect tracking, analytics, reporting, integration via REST APIs, and compliance use cases like food traceability under FSMA Section 204 using GS1 standards. The hardware needed includes RFID readers, antennas, tags, and a controller; software is browser (cloud) + mobile.
