SIVA – RE-LOAD PRO 7320 DUO-FRE – Dual-Frequency UHF + NFC RFID Label

The SIVA RE-LOAD PRO 7320 DUO-FRE is a dual-frequency UHF + NFC RFID label designed for returnable transport items (RTIs), reusable packaging, and industrial assets that require both long-range identification and short-range interaction. By combining UHF RFID for automated logistics tracking with NFC for close-range scanning and customer engagement, this label enables seamless data flow across supply chains and digital touchpoints.

A key differentiator is its shared memory architecture, allowing both the UHF and NFC interfaces to access the same data set. This simplifies data management across warehouse systems, ERP platforms, mobile devices, and consumer applications, eliminating the need for duplicate records or synchronization layers.

Built to withstand high-temperature chemical washing and industrial handling, the RE-LOAD PRO 7320 DUO-FRE is ideal for closed-loop logistics, food & beverage crates, reusable containers, manufacturing RTIs, pooling systems, and smart asset identification where durability and data consistency are critical.
