Description

This passive RFID tag operates at the 125KHz frequency, utilizing the EM4305/T5577 chipset to provide a reliable, read-only identification signal. The tag is inductively powered by the reader’s RF field, requiring no internal battery, and transmits its unique 32-bit identifier upon activation.

Encased in a smooth, mildly flexible ABS plastic shell, the tag is designed for durability and environmental resistance. Its integrated keyring loop facilitates easy deployment in access control, asset management, and pet tracking systems, where it can be read by a network of compatible 125KHz RFID readers.

Key Features

  • 125KHz RFID operation for broad compatibility with access control readers and duplicators
  • Durable, waterproof ABS plastic construction for long-term reliability
  • Factory-locked 32-bit unique identifier for secure, non-clashing asset tagging
  • Integrated keyring provides versatile mounting and attachment options
  • Passive design requires no internal power source, enabling maintenance-free operation
  • Blank, smooth yellow surface allows for custom branding or hand-written labels
  • Compact and lightweight form factor for discrete integration into systems

Applications

  • Physical access control systems for doors, gates, and turnstiles
  • Asset tracking and inventory management in warehouses and offices
  • Pet identification and location tracking via reader networks
  • Time and attendance logging for personnel in secure facilities
  • Parking garage and vehicle access authorization

Frequently Asked Questions

Is this RFID tag reprogrammable?

No, this tag is not reprogrammable. It contains a factory-programmed EM4305/T5577 chip with a unique, locked 32-bit identifier. It is designed for read-only operation with standard 125KHz RFID readers and duplicators.

What is the operating frequency and read range?

This tag operates at 125KHz. As a passive tag, it has no internal battery and is powered inductively by the reader's RF field. The typical read range is a few centimeters, depending on the power and antenna design of the reader.

What is the tag housing made of, and is it durable?

The tag is housed in a durable, waterproof ABS plastic shell. This construction provides good resistance to moisture, impacts, and everyday wear, making it suitable for use on keyrings, pet collars, or attached to assets.

Can this tag be used with Arduino or Raspberry Pi?

Yes, but it requires an external 125KHz RFID reader module (like an RDM6300 or similar) connected to your microcontroller. The tag itself is passive; the reader module handles the RF communication and outputs the tag's ID serially for your project to process.
