RFID Key Fob – Structure, Applications & Custom RFID Keychain Solution

En RFID key fob is a compact identification device that integrates radio frequency identification (RFID) technology into a portable keychain form.
It is widely used for identity recognition, access control, payment systems, and asset management.
With a simple structure, stable performance, and easy portability, RFID key fobs are ideal for both commercial and industrial applications.

Structure Composition of RFID Key Fob

1. Housing

The housing is typically made of ABS, PVC, PET, or metal, designed to protect internal components and ensure long-term durability.

Functions:

• Protection: Shields the RFID chip and antenna from water, dust, and physical impact

• Identification: Supports logo printing, numbering, or custom markings

• Portability: Keychain-style design for easy attachment to keys, bags, or lanyards

2. RFID Chip

The RFID chip is the core component, responsible for data storage and communication with the reader.

Chip Types by Frequency:

• Low Frequency (LF, 125 kHz):
  Suitable for basic identification, access control, and attendance systems

• High Frequency (HF, 13.56 MHz):
  Commonly used in secure access control, membership systems, and payment applications

• Ultra-High Frequency (UHF):
  Designed for long-range identification and logistics tracking

3. Antenna

The antenna enables wireless communication between the key fob and the RFID reader.

Características:

• Made of copper or aluminum wire

• Captures electromagnetic signals from the reader

• Transmits data stored in the RFID chip

• Antenna size and shape are optimized according to operating frequency

4. Internal Filling Material

Internal filling materials, such as epoxy resin, are used to fix and protect the chip and antenna.

Functions:

• Prevents component movement

• Enhances resistance to vibration and drops

• Improves overall product reliability
