Which RFID tags are most compatible with 860-960MHz UHF reader modules?

UHF RFID reader modules (e.g., ​CK-M8 UHF Module) operating in the 860-960MHz range require tags optimized for frequency, material, and environmental conditions. Below are the ​top tag types and best practices for compatibility:

​1. ​EPC Gen2v2 (ISO 18000-63) Tags**

• ​Why They Work: Designed specifically for global UHF RFID systems, these tags support high-speed, high-volume scanning.
• ​Best For: Logistics, retail inventory, and pallet tracking.
• ​Examples:
  • ​Inlays: Flexible paper/PET tags for carton labeling (read range: 6–8m).
  • ​Anti-Metal Tags: Foam-backed tags for metal surfaces (read range: 4–6m).

​2. ​High-Performance Tags for Challenging Environments**

• ​Metal Surfaces: Use ​ferrite-loaded tags (e.g., ​RFID Metal Tag) to prevent signal reflection.
• ​Liquid Containers: Opt for ​near-field UHF tags  with shorter read ranges (10–50cm) to avoid absorption.

​3. ​Regional Frequency Optimization**

• ​FCC (North America): Tags tuned to ​902-928MHz (e.g.,  FCC Tag) maximize performance with RM-45 modules in the U.S.
• ​ETSI (EU): Tags operating at ​865-868MHz (e.g.,  ETSI Tag) comply with European regulations.

​4. ​Key Compatibility Factors**

• ​Chip Sensitivity: Tags with ​high sensitivity chips (-18dBm or better) work best with low-power reader modules.
• ​Antenna Design: Dual-dipole tags ensure omnidirectional readability in dynamic environments.

​5. ​Testing & Validation**

• Use a ​UHF RFID tester to measure ​tag sensitivity and ​read range with your reader module.
• Test tags on actual materials (wood, metal, plastic) to avoid real-world surprises.

Pro Tip: For mixed environments, deploy ​hybrid RFID tags that combine UHF and NFC capabilities.
