TallyFlow IoT is a high-performance, enterprise-grade software platform that unifies RFID reader and barcode scanner data across multiple manufacturers and device types. Built with Rust for exceptional reliability and performance, TallyFlow IoT provides a single, powerful interface to manage RFID, barcode and imaging hardware data flows.

 

TallyFlow IoT currently supports Impinj and Zebra fixed RFID readers, plus Zebra SNAPI and Aurora-based barcode scanners and imaging, while delivering real-time data streaming, comprehensive REST APIs, and an intuitive web-based interface. Printing and photo capture support is expected in Q1 2026.​​
