## What is this product?
This 30mm round, anti-tamper NFC sticker is built for secure authentication and tamper-evident labeling. It uses NXP’s trusted NTAG213 chip and a high-strength 3M adhesive to create a permanent bond—if someone tries to remove it, the chip physically separates from the sticker, permanently disabling its NFC functionality. Designed for B2B buyers in industries like brand protection, logistics, and healthcare, it’s the solution for businesses needing to verify product authenticity and detect tampering without specialized tools.
## Key Features & Benefits
– **Unbreakable Tamper Evidence**: The chip detaches from the sticker upon removal, making reuse impossible—critical for anti-counterfeiting and proving product integrity.
– **Universal NFC Compatibility**: NXP NTAG213 (NFC Forum Type 2 compliant) works with 99% of NFC-enabled devices, including smartphones and standard readers—no special hardware needed.
– **Harsh Environment Durability**: 3M 467MP adhesive bonds to plastic, metal, or paper surfaces, withstanding temperatures from -40°C to 150°C for reliable performance in extreme conditions.
– **Scalable Bulk Pricing**: Tiered pricing starts at $1.10/unit (1–24 units) and drops to $0.49/unit for 1,000+ orders—ideal for high-volume needs.
– **Reliable Tamper Mechanism**: Rigorously tested for 99.9% accuracy, ensuring no false positives or failures when detecting removal attempts.
## Real-world Applications
Deploy this tag where tamper evidence and authenticity are non-negotiable:
– **Brand Protection**: Authenticate luxury goods, electronics, or pharmaceuticals at point-of-purchase to combat fakes.
– **Supply Chain Security**: Track high-value assets like industrial tools or medical equipment to detect unauthorized handling during transit.
– **Secure Labeling**: Tamper-proof labels for sensitive documents, warranty cards, or serialized components to prevent fraud.
– **Anti-Counterfeiting**: Disable counterfeit attempts by making tags unreadable once removed, rendering stolen or copied products unauthentic.
