Technologies Used
RFID tags for metal surfaces use advanced design techniques to ensure reliable performance:
- Anti-Interference Substrates: Foam, ferrite, or ceramic layers isolate the tag from metal reflection
- Tuned Antennas: Optimized to exploit or neutralize metals reflective properties
- Spacer Design: Creates a gap between the tag and metal to prevent detuning
- UHF Protocols (ISO 18000-6C): Most common for long-range, high-speed reads
Construction Details
- Materials:
- ABS or polycarbonate casing for ruggedness
- Ferrite or foam backing for signal isolation
- Adhesive or bolt-on mounting options
- Form Factors:
- Flat labels for laptops and servers
- Bolt-on tags for pipes and valves
- Embedded tags for tools and molds
Application Areas
RFID tags for metal surfaces are widely used in:
- Industrial Asset Tracking: Pipes, valves, machinery
- IT Asset Management: Servers, laptops, data center equipment
- Healthcare: Medical devices, sterilization trays
- Aerospace & Defense: Aircraft components, tools
- Construction: Steel beams, scaffolding
- Manufacturing: Automotive parts, production lines
Advantages
- Reliable Performance on Metal: Designed to overcome RF interference
- Durability: Resistant to heat, chemicals, and physical stress
- Flexible Form Factors: Suitable for flat, curved, and embedded surfaces
- Long Read Range: Optimized antenna design enables efficient scanning
- Improved Asset Visibility: Enables real-time tracking and inventory control
