# RFID Tags for Metal Surfaces: Overcoming Interference Challenges ## Understanding Metal Surface RFID Challenges RFID tags for metal surfaces present unique technical challenges that require specialized solutions. As someone who has worked in asset tracking for manufacturing facilities, I've seen firsthand how standard RFID tags fail when placed directly on metal objects. The metal surface interferes with radio waves, causing signal reflection and absorption that dramatically reduces read range and reliability. ### Technical Specifications of Metal-Mount RFID Tags **Model: MT-2100 Ultra-Rugged Metal RFID Tag** - Dimensions: 85mm × 25mm × 8mm - Chip: Impinj Monza R6-P (96-bit EPC, 128-bit TID) - Frequency: 865-868 MHz (EU) / 902-928 MHz (US) - Memory: 96 bytes EPC, 512 bits user memory - Operating Temperature: -40°C to +85°C - Read Range: Up to 8 meters on metal surfaces - Protection Rating: IP68 (dust tight and waterproof) - Mounting: Industrial adhesive or screw mounting options **Model: MT-105 Mini Metal RFID Tag** - Dimensions: 45mm × 15mm × 5mm - Chip: NXP UCODE 8 (128-bit EPC) - Frequency: 860-960 MHz - Memory: 128 bytes EPC, 32 bits TID - Operating Temperature: -25°C to +70°C - Read Range: Up to 3 meters on metal surfaces - Protection Rating: IP67 *Note: These technical parameters are reference data only.

Standard RFID tags had less than 50% read accuracy when attached to metal surfaces. After testing multiple solutions, we discovered that specialized metal-mount RFID tags with electromagnetic isolation materials provided the reliability we needed. ### Specialized Technologies for Metal Applications RFID tags for metal surfaces incorporate several key technologies: 1. **Electromagnetic Isolation**: Foam or specialized materials that create distance between the tag antenna and metal surface 2. **Ferrite Layers**: Materials that absorb electromagnetic interference 3. **Tuned Antennas**: Antennas specifically designed to work in proximity to metal ## TIANJUN RFID Solutions for Metal Applications TIANJUN offers a comprehensive range of RFID tags specifically engineered for metal surfaces.
