Structure Composition of RFID Key Fob<\/h2>\n

1. Housing<\/h3>\n

The housing is typically made of ABS, PVC, PET, or metal<\/strong>, designed to protect internal components and ensure long-term durability.<\/p>\n

Functions:<\/strong><\/p>\n

    \n
  • \n

    Protection:<\/strong> Shields the RFID chip and antenna from water, dust, and physical impact<\/p>\n<\/li>\n

  • \n

    Identification:<\/strong> Supports logo printing, numbering, or custom markings<\/p>\n<\/li>\n

  • \n

    Portability:<\/strong> Keychain-style design for easy attachment to keys, bags, or lanyards<\/p>\n<\/li>\n<\/ul>\n

    \n

    2. RFID Chip<\/h3>\n

    The RFID chip is the core component, responsible for data storage and communication with the reader.<\/p>\n

    Chip Types by Frequency:<\/strong><\/p>\n

      \n
    • \n

      Low Frequency (LF, 125 kHz):<\/strong>
      Suitable for basic identification, access control, and attendance systems<\/p>\n<\/li>\n

    • \n

      High Frequency (HF, 13.56 MHz):<\/strong>
      Commonly used in secure access control, membership systems, and payment applications<\/p>\n<\/li>\n

    • \n

      Ultra-High Frequency (UHF):<\/strong>
      Designed for long-range identification and logistics tracking<\/p>\n<\/li>\n<\/ul>\n

      \n

      3. Antenna<\/h3>\n

      The antenna enables wireless communication between the key fob and the RFID reader.<\/p>\n

        \n
      • \n

        Made of copper or aluminum wire<\/p>\n<\/li>\n

      • \n

        Captures electromagnetic signals from the reader<\/p>\n<\/li>\n

      • \n

        Transmits data stored in the RFID chip<\/p>\n<\/li>\n

      • \n

        Antenna size and shape are optimized according to operating frequency<\/p>\n<\/li>\n<\/ul>\n

        \n

        4. Internal Filling Material<\/h3>\n

        Internal filling materials, such as epoxy resin<\/strong>, are used to fix and protect the chip and antenna.<\/p>\n

        Functions:<\/strong><\/p>\n
