Core Business
Quanray focuses on the research, design, and manufacturing of Green Passive IoT solutions, delivering battery-free, ultra-low-power RFID chips, tags, readers, and system-level hardware platforms.
The company builds sustainable and cost-effective IoT data acquisition infrastructure based on three core passive technologies:
- Near-field Passive IoT: Advanced RFID+ chips and tags (UHF / HF / LF / DF) with integrated sensing capabilities such as temperature and tilt, enabling identification, monitoring, and traceability at close range.
- Local-area Passive IoT: Battery-free Bluetooth AoA (Angle of Arrival) solutions that deliver centimeter-level indoor positioning and asset tracking without batteries.
- Wide-area Passive IoT: Ambient IoT (AIoT) solutions that harvest ambient energy—such as from 5G-A networks—to enable long-distance, massive-scale connectivity without traditional power sources.
These technologies support ESG-driven sustainability goals while enabling enterprises to scale IoT deployments efficiently and responsibly.
Featured Products at the Exhibition
Passive RFID Chips, Battery-Free Tags, and Ambient IoT Devices
The Qstar-7U is a cost-effective EPC Gen2V2 RFID chip offering excellent read and write sensitivity. Featuring 144-bit EPC memory and 128-bit user memory, it supports fast inventory, self-checking, anti-counterfeiting, and full traceability.
Multiple versions are available to meet diverse application requirements while maintaining high quality and competitive pricing, making it ideal for large-scale item-level deployments.
Application Areas:
- Item-level tagging (apparel and retail)
- Logistics and supply chain management
- Pallet and case tracking
- Asset management
- Medical and healthcare identification
The battery-free ePaper tag is developed based on Quanray’s UHF RFID chip technology. It utilizes RF energy harvesting to power ePaper display updates, completely eliminating the need for batteries.
This solution enables real-time, wireless content updates while significantly reducing maintenance costs and environmental impact.
Application Areas:
- Retail & Promotion: Dynamic pricing, promotional displays, and packaging labels with real-time updates, reducing manual errors and enhancing customer engagement.
- Warehousing & Logistics: Second-level inventory updates, paperless operations, reduced labor intensity, and improved safety in high-risk environments. Automated data capture reduces error rates by over 60% and boosts operational efficiency.
The BT01 is a passive Bluetooth Low Energy (BLE 5.3) beacon powered entirely by solar energy, requiring no battery replacement. It supports a broadcast range of up to 120 meters in open areas and features strong resistance to metal interference, allowing direct installation on metal surfaces.
When paired with Bluetooth AoA gateways, the BT01 enables precise asset inventory, location tracking, and access management.
Application Areas:
- Automated Inventory: Contactless warehouse stock counting via Bluetooth gateways
- Mobile Asset Tracking: Zone-level positioning for movable equipment
- Smart Logistics: Simplified inbound and outbound management without RFID angle or distance constraints
