What Are Tamper-Evident RFID Tags? Where Are They Used?
Tamper-evident RFID tags are an effective solution for companies that want to ensure product security, detect unauthorized tampering, and prevent counterfeiting. These special tags self-destruct and become unusable once removed after being applied.

What Is a Tamper-Evident RFID Tag?
These tags are security-focused labels produced with RFID technology that structurally break down, leave traces, or render the chip non-functional when removed from the surface they are attached to. Although physically removable, such tampering is clearly noticeable, and the tag becomes unusable afterward.

How Does It Work?
The tag transmits data with RFID readers as long as it is active. However, when the tag is removed:

• Its adhesive surface is damaged and leaves a mark (for example, the word "VOID" appears),

• The tag is physically torn or broken,

• The RFID chip or antenna is damaged and becomes unreadable.
  Thus, reusing or unauthorized transfer of the tag is prevented.

Usage Areas

• Electronic product packaging: Checking if the box has been opened.

• Warranty and service labels: Stuck on device covers to detect tampering.

• Logistics security: Preventing unauthorized opening of shipments and packages.

• Anti-counterfeiting: Monitoring unauthorized openings of original products.

• Retail: Guaranteeing the integrity of valuable product packages.

Advantages

• High Security: Removing the tag leaves physical marks or causes it to be unrecognized in digital systems.

• Single Use: Eliminates the risk of counterfeiting and reusing the tag.

• Data Integration: Thanks to the RFID chip, product information, stock status, or warranty process can be tracked digitally.

• System Alert: Removed tags can be recognized as "invalid" in the system.

Tag Features

• Can operate at UHF or HF frequencies.

• May be made of paper, polyester, or VOID material.

• Suitable for small sizes and flat surfaces.

• Usually suitable for combined barcode/RFID use.

Who Should Use Them?

• Electronics and technology manufacturers

• Logistics and cargo companies

• Medical and pharmaceutical manufacturers

• All manufacturers who want to protect their brand

Conclusion
Tamper-evident RFID tags not only ensure product security but also increase consumer trust. They are an effective technological step among tamper detection, warranty protection, and anti-counterfeiting measures. If you want to protect your brand and products, you can create a more transparent and secure supply chain by integrating these types of tags with your RFID infrastructure.
