SIVA – UNI™ 6326 TP DUO-FRE Dual-Frequency UHF + NFC Tamper-Proof RFID Label

The SIVA UNI™ 6326 TP DUO-FRE is a dual-frequency UHF + NFC RFID label designed for secure identification, brand protection, and customer engagement. Combining UHF RFID for long-range supply chain tracking with NFC for smartphone interaction, this label enables seamless data sharing across enterprise systems and consumer-facing applications.

Built with a tamper-proof security design, the label cannot be removed intact—any attempt to transfer it results in visible breakage. This makes it ideal for anti-counterfeiting, warranty validation, asset authentication, sealed packaging, and secure labeling.

A key differentiator is its shared memory architecture, allowing both the UHF and NFC interfaces to access the same user memory. This enables unified data handling between logistics systems, ERP platforms, and mobile NFC experiences, reducing complexity and improving traceability across the product lifecycle.
