FAQ of SeeMore IoT Products
  • How to start a RAIN RFID project?
  • Follow our 5-step framework:

    1. Tag selection: Test FL/AT/PT series samples on actual items

    2. Reader placement: Use our free Site Planner tool

    3. Regulatory check: Confirm local frequency rules

    4. Pilot deployment: Validate with 50-100 tagged items

    5. Scale with SDKs: Integrate data into WMS/ERP via Java/.NET APIs
      Next Step: Download our "RAIN RFID Implementation Checklist".

  • What frequency regulations apply globally?
  • UHF RFID bands vary by region:

    • FCC: 902-928 MHz (Americas)

    • ETSI: 865-868 MHz (Europe)

    • CMII: 920-925 MHz (China)

    • More: customizable or adjustable
      Key: All SeeMore readers (e.g., Aura series) support multi-region firmware switching.

  • What determines RFID read range?
  • Read distance depends on:

    • Reader power (max 33dBm in FCC regions)

    • Antenna gain (6dBi vs. 12dBi doubles range)

    • Tag sensitivity (e.g., Impinj M781 RFID tag chip)

    • Environment (metal/liquid can reduce range by 70%)
      Note: Our FL13042 tags achieve max 20m on metal surfaces.

  • Why choose RAIN RFID over barcodes?
  • RAIN RFID (UHF) enables:

    • No line-of-sight scanning (read through boxes)

    • Simultaneous reads (entire pallets in seconds)

    • Rewriteable data (track maintenance history)

    See SkyLink H70 PDA demonstrations showing 200% faster inventory vs barcodes.

  • How do I select UHF RFID antennas?
  • Match antenna types to your environment:

    Antenna Type Best For Product Example
    Circular Polarized Tags at random orientations (e.g., retail) SA092 Indoor (9dBi)
    Linear Polarized Fixed tag alignment (e.g., conveyors) SA122 Outdoor (12dBi)
    Near-Field Close-range precision (e.g., medical tools) SA300N Embedded
    Pro Tip: Pair SA121 antennas with Symo FR04 Pro for 30m+ vehicle tracking.
  • How do passive RFID tags work without batteries?
  • Passive RFID tags harvest energy from the RFID reader's signal via antenna coupling.  Our UHF RFID tags activate within milliseconds, bouncing back data up to 10-30m away - perfect for pallet tracking or retail inventory.

  • What’s the real-world difference between HF and UHF RFID?
  • HF (13.56MHz): Short-range (Usually <10cm), excels in security (e.g., payment systems)

    UHF (860-960MHz): Our specialty!  Long-range (1-30m) + bulk reading (600+ tags/sec).  Used in 80% of industrial applications like warehouse logistics with readers like Symo FR04 Pro
