What is this product?
This is a specialized anti-tamper NFC tag built for high-value jewelry—engineered with NXP’s ICODE SLIX chip to deliver secure authentication, theft protection, and inventory tracking. If you’re searching for a lightweight, discreet solution to verify luxury jewelry, prevent counterfeiting, or track assets, this tag is designed to loop around rings, necklaces, or bracelets without adding bulk, making it ideal for daily wear and high-stakes security needs.
###
Key Features & Benefits
- Durable for Daily Wear: Made from flexible PET material (resistant to scratches, moisture, and bending), it withstands the rigors of everyday use on delicate jewelry pieces—no need to worry about wear and tear.
- Anti-Tamper Detection: Engineered to detect unauthorized removal attempts. If someone tries to peel or cut the tag, its tamper-evident design triggers a permanent state change, alerting you to potential theft or counterfeiting.
- NXP ICODE SLIX Chip: Trusted for robust performance, long read ranges (up to 10cm with standard NFC readers), and seamless compatibility—ensuring your team can verify jewelry quickly, whether in-store or during inventory checks.
- Customizable Data Storage: Each tag stores a unique UID (factory-encoded or custom-programmable) plus details like design specs, provenance, or warranty info—tailored to your brand’s tracking needs.
###
Real-world Applications
Perfect for jewelry manufacturers, luxury brands, and asset managers tackling these scenarios:
- Authentication at Point-of-Sale: Let customers scan the tag with their phones to instantly verify a diamond ring’s authenticity, boosting trust in your brand.
- Inventory & Asset Tracking: Track high-value pieces in warehouses, retail displays, or during transit—no more manual logbooks or misplaced items.
- Theft Prevention: Detect tampering in storage or transit; if a tag is compromised, you’ll know immediately to investigate.
- Enhanced Customer Experience: Embed product stories, care tips, or warranty details in the tag—turning a security tool into a touchpoint for engagement.
