OpenRFID Simulator — Virtual RFID Reader & EPC Emulator

Production-grade open-source RFID simulator for testing enterprise RFID middleware, warehouse automation, and asset tracking software without physical RFID readers. Simulates LLRP (Low Level Reader Protocol), TCP socket, and Serial reader interfaces while generating high-throughput EPC Class 1 Gen 2 (ISO 18000-6C) RFID tag streams. Features adjustable RF signal strength (RSSI), antenna port switching, custom memory bank payloads (EPC, TID, User memory), and interactive Web GUI / CLI controls for automated unit and integration testing.
