An ABS RFID tag with a 25mm diameter and with a hole operating at LF (Low Frequency) is a specialized RFID tag designed for various tracking and identification purposes. Here's a detailed description:

1. Material: ABS (Acrylonitrile Butadiene Styrene)

• Durability: ABS is a tough, impact-resistant plastic that is commonly used in RFID tags for providing protection to the internal chip and antenna. It ensures that the tag is resilient to wear and tear in various environments.
• Weather Resistance: ABS offers good resistance to heat, chemicals, and environmental factors, making it suitable for both indoor and outdoor applications.

2. Diameter: 25mm

• Compact Size: With a 25mm diameter, the tag is relatively small and convenient to attach to various objects or assets while providing sufficient space for embedding the RFID chip and antenna.
• Versatility: This size is ideal for applications where the tag needs to be small but still easily identifiable and readable by an RFID reader.

3. With Hole

• Mounting: The hole in the tag allows for easy attachment to items, such as via a screw, cable tie, or other fastening methods. This feature is useful for assets that need to be physically secured or mounted.
• Flexibility: The hole provides additional flexibility for users to incorporate the tag into various setups, especially when it needs to be fixed onto equipment, machinery, or inventory.

4. LF (Low Frequency) RFID

• Frequency Range: The LF RFID tag operates within the 125 kHz frequency range, which is lower than HF (High Frequency) or UHF (Ultra High Frequency) tags. LF RFID has a shorter range and is typically used for close-proximity identification.
• Read Range: LF RFID tags generally have a read range of 5-10 cm (about 2-4 inches), depending on the specific tag and environment.
• Compatibility: LF tags are often used in applications like animal tracking, access control, and industrial automation where long-range scanning is not required.
• Data Storage: These tags typically store a small amount of data, such as a unique identification number, which is transmitted to the reader.

5. Applications

• Asset Management: Tracking tools, equipment, or other small items where the tag can be securely fastened using the hole.
• Animal Identification: Commonly used for pet tracking or livestock identification.
• Access Control: For entry systems where tags are mounted on keychains, badges, or other devices that can be easily secured with a hole.
• Inventory Control: Used in warehouse management or retail settings to track goods and items.

6. Advantages

• Cost-Effective: LF RFID tags tend to be relatively inexpensive and are widely used in applications that don’t require high-speed data transfer.
• Robust and Reliable: ABS material and LF frequency make these tags highly reliable in environments with high metal content or interference from other signals.

An ABS, 25mm diameter, LF RFID tag with a hole is a durable, easy-to-mount identification device that operates at low frequencies for close-range tracking and management. It's a versatile option for asset tracking, access control, and other identification systems where secure attachment and reliability are essential.
