Global Cards | Top Quality RFID Cards

RFID systems operate across various frequency ranges and types, each with distinct characteristics and applications. Below is an overview of the main types of frequencies:

1. Low Frequency (LF) RFID:

  • Frequency Range: 30 kHz to 300 kHz (typically 125 kHz or 134 kHz)
  • Read Range: Short (up to 10 cm)
  • Characteristics:
    • Lower data transfer rates.
    • Good penetration through non-metallic materials.
    • Less susceptible to interference from water or metal compared to higher frequencies.
    • Lower cost.
  • Applications:
    • Access control.
    • Animal tracking.
    • Industrial applications.

2. High Frequency (HF) RFID:

  • Frequency Range: 3 MHz to 30 MHz (typically 13.56 MHz)
  • Read Range: Short to medium (10 cm to 1 m)
  • Characteristics:
    • Moderate data transfer rates.
    • Moderate sensitivity to interference.
    • Widely used in smart card applications.
  • Applications:

3. Ultra-High Frequency (UHF) RFID:

  • Frequency Range: 300 MHz to 3 GHz (typically 860 MHz to 960 MHz)
  • Read Range: Long (up to 12 m)
  • Characteristics:
    • High data transfer rates.
    • More susceptible to interference from metal and liquids.
    • Lower cost tags.
  • Applications:
    • Inventory management.
    • Supply chain tracking.
    • Retail applications.
    • Toll collection.

Key Considerations:

  • Read Range: The distance at which a reader can communicate with a tag.
  • Data Transfer Speed: The rate at which data can be exchanged.
  • Interference: The susceptibility of the signal to disruption from other materials or signals.
  • Cost: The cost of tags and readers varies by frequency.
  • Regulations: Frequency regulations vary by region.

Comprehending these RFID frequency types is essential for choosing the right RFID technology for a particular application.
