Next-Generation Three-State RFID Container Seals: The Soter Seal
Revolutionize your cargo tracking with the Soter Seal, a heavy-duty UHF RFID bolt-lock engineered for ultimate supply chain transparency in India. As a pioneer in smart logistics, the Soter Seal is the first RFID bolt seal compliant with ISO 17712:2013 technical standards that features three-state detection. This means the integrated chip permanently records and broadcasts its exact status: UNLOCKED, LOCKED, or TAMPERED. By deploying these advanced container seals, Indian port authorities and fleet managers can eliminate guesswork and guarantee cargo security at every checkpoint.
Hardware-Based Security & Impenetrable Physical Defense
Unlike competing products that rely on vulnerable external software algorithms, the Soter Seal’s security is strictly hardware-based, utilizing the latest generation NXP RFID chip. Physically, it combines the immense mechanical security of a carbonitrured steel pin with a durable polypropylene plastic housing. It is a robust, tamper-evident fortress designed to withstand the harsh environmental conditions of long-haul transport and oceanic freight.
