Fiber marking animal ear tags with Laser & RFID

Fiber laser engraving of animal ear tags is today the most reliable and permanent solution for tagging sheep, goats, cattle and other livestock. Combined with RFID technology and automation, it delivers high productivity, accuracy and full traceability.

At CNC Laser Deals we have developed our own specialized application that enables simultaneous laser engraving of ear tags and writing of the RFID chips, offering a complete production system for industrial use and large batches.

What animal ear tags are and why they require laser marking

Animal ear tags are used for identification, registration and traceability in accordance with European and international specifications. The marking must be:

• permanent and indelible
• legible for years
• resistant to sun, moisture, abrasion and chemicals
• compatible with RFID systems

Fiber laser engraving outperforms printing or hot stamping, as it does not fade or wear off.

Fiber Laser Marking on plastic ear tags

Modern fiber lasers can engrave the special polymer plastics used in ear tags, creating high contrast without damaging the material.

The engraving includes:

• animal number
• country code
• organization logo
• barcode / QR where required

RFID animal ear tags – why they are essential

RFID ear tags enable electronic identification of animals on livestock farms, in slaughterhouses and in control systems.

Each ear tag contains an RFID chip that must:

• be written with a unique ID
• be matched to the laser-engraved ID
• be checked for correct operation

Our custom application (Laser + RFID together)

We have developed a proprietary production application that integrates:

• the fiber marking machine
• the RFID reader / writer
• the batch database

With our application:

• the RFID chip is read
• the unique ID is written to the chip
• the same ID is laser-engraved simultaneously
• the write is verified for validity
• the result is recorded in the database

Maximum automation & productivity

The system is designed for mass production of ear tags, reducing:

• human errors
• handling time
• rejects due to laser–RFID mismatch

Production runs at a steady rate, ideal for large orders from organizations, cooperatives and manufacturers.

Advantages of our solution

• 100% laser & RFID matching
• full traceability
• regulatory compliance
• flexibility in formats & data
• customizable per client

Applications

• Sheep and goat ear tags
• Cattle ear tags
• Government tagging programs
• Private certification bodies
• Ear tag manufacturers

Frequently Asked Questions (FAQ)

Does engraving damage the ear tag plastic?

No. Engraving is performed with controlled parameters without affecting mechanical strength.

Can the application be adapted to different RFID chips?

Yes. The application is modular and adapts to different RFID protocols.

Is there a write-failure check?

Yes. Each ear tag is checked automatically before it is marked as complete.
