In the area of industrial asset management, metal surfaces have long posed a challenge for traditional RFID tags—electromagnetic interference disrupts signal transmission, rendering most tags useless. However, HF (High-Frequency) Flexible On Metal Tags have emerged as a thing that changes the status quo, and as a 20-year veteran smart card manufacturer, Zhanfeng Smart Card is here to unpack this technology and its practical value.
What Makes HF Flexible On Metal Tags Unique?
Unlike traditional rigid PCB anti-metal tags, HF flexible versions combine functionality with adaptability through following two core innovations:
Special Isolation Layer: A 0.8-1.2mm flexible dielectric layer (e.g., foam or ceramic-filled materials) creates a "virtual non-metal space" between the tag antenna and metal surface, reducing eddy current loss by over 90% . This design ensures stable performance even when attached to curved metal assets like pipes or tool casings.
Industrial-Grade Flexibility: Constructed with PET/PI film substrates and etched aluminum antennas, these tags bend without damaging performance—ideal for irregular surfaces where rigid tags fail . At just 0.46-1.2mm thick, they remain unobtrusive while withstanding moisture, oil, and temperatures ranging from -40℃ to 85℃.
Key Applications Across Industries
The versatility of HF flexible on-metal tags solves pain points in various fields:
Manufacturing: Track metal tooling, production line components, and automotive parts with 99.8% identification accuracy, cutting inventory checks from hours to minutes.
Logistics: Attach to metal shipping containers or pallets for real-time supply chain visibility—compatible with standard HF readers for seamless warehouse integration.
Healthcare: Label surgical instruments and medical equipment; their IP68 waterproof rating survives repeated sterilization cycles.
