What Determines the Price of Dual Frequency RFID Tags?
Dual Frequency RFID Tags combine two distinct operating frequencies—typically HF (13.56 MHz) and UHF (860–960 MHz)—in a single device. This hybrid design leverages the strengths of both bands: HF excels in security, near-field precision, and compatibility with metal/liquid environments, while UHF offers longer read ranges (up to 10 meters) and faster multi-tag scanning178. For applications requiring both high-security data transmission (e.g., access control) and efficient inventory tracking, these tags eliminate the need for separate systems. However, their advanced functionality comes at a higher cost compared to single-frequency tags. Below, we break down the key factors influencing their pricing.
Key Cost Drivers
Antenna Design and Integration Complexity
Unlike single-frequency tags, dual-frequency versions require two independent antennas or a single intricately tuned antenna structure to operate across distinct bands without interference. For instance, HF antennas rely on inductive coupling (magnetic fields), while UHF antennas use electromagnetic wave propagation18. Merging these into a compact form demands specialized materials and multilayer circuitry, increasing R&D and manufacturing costs. Mutual interference between frequencies must also be rigorously mitigated, adding to design overhead1.
Chip Technology and Customization
Dual-frequency tags often integrate two specialized chips: an HF chip for secure transactions and a UHF chip for long-range scanning. Advanced models may use a single custom ASIC supporting both frequencies, which reduces size but raises semiconductor complexity and cost17. Chips with higher memory capacity (e.g., for storing encryption keys or sensor data) or enhanced security features (e.g., 2-byte encryption or password protection) further elevate prices27.
Materials and Durability Requirements
Tags designed for harsh environments (e.g., industrial warehouses or outdoor use) incorporate robust materials like ABS plastic, brass, or aluminum casings. These materials shield internal components from physical stress, moisture, and temperature extremes but increase production expenses25. Additionally, UHF performance degrades near metal/liquid surfaces, necessitating specialized shielding layers in dual-frequency tags—another cost adder8.
Frequency-Specific Components
HF Components: Require precision-tuned copper coils for magnetic coupling, increasing material and labor costs8.
UHF Components: Depend on etched or printed antennas optimized for specific sub-bands (e.g., 865–868 MHz in Europe vs. 902–928 MHz in the U.S.), requiring region-specific designs and testing48.
Economies of Scale
While single-frequency UHF tags now cost as little as $0.10, dual-frequency variants remain niche products with lower production volumes7. Limited standardization also complicates mass production. As adoption grows—especially in supply chain management and secure access systems—prices are expected to decrease.
Why Invest in Dual-Frequency RFID Tags?
Despite higher upfront costs (typically 2–5× more than UHF-only tags), these tags offer unparalleled versatility:
Security + Range: Authenticate high-value assets via HF while tracking them over large areas via UHF17.
Regulatory Flexibility: Operate globally by switching between frequency bands to comply with regional regulations8.
System Consolidation: Replace separate HF/UHF infrastructure with a unified solution, reducing long-term hardware and maintenance expenses.
