Secure Passive Seal

Long-Range, Battery-Free Security Seal with Wireless Localization and Tamper Detection

Dirac Solutions Inc. (DSI) has developed the industry’s first long-range, battery-free RFID security seal that combines secure identification, wireless interrogation, precise localization, and real-time tamper detection—all in a maintenance-free, environmentally friendly form factor.

Key Features and Capabilities:

  • Battery-Free Operation with Unlimited Lifetime The seal operates without any internal power source, offering permanent, zero-maintenance deployment—ideal for long-term use in high-security environments where reliability and sustainability are paramount.
  • Wireless Interrogation with Long Read Range Supports long range wireless tamper monitoring, enabling fast and secure remote interrogation via fixed or mobile readers. Suitable for gates, containers, high-value assets, or sealed doors in logistics, defense, and nuclear facilities.
  • Accurate Localization Integrated with DSI’s ultra-wideband localization engine, the seal provides position tracking of sealed items or containers—essential for automated inventory auditing and asset integrity assurance in storage or transit.
  • Tamper Detection with Visual and Audible Alerts The system monitors for any tampering or breach attempts and triggers real-time alerts, which can include visual indicators or audible alarms, depending on the deployment configuration. These alerts can also be networked to central monitoring systems.
  • Authenticated & Secure Identification Each tag includes hardware-level authentication, preventing spoofing or unauthorized replacement—ensuring chain-of-custody integrity and high-value asset protection.
  • Optimized for Harsh RF Propagation Environments Engineered for reliable use near metallic surfaces, dense structures, and cluttered RF zones, where conventional RFID seals are unreliable.
  • Radiation-Hardened for Extreme Environments Constructed with materials and designs that provide resistance to gamma radiation and high levels of fast neutron exposure, enabling use in nuclear sites, weapons depots, and radiological containment areas.
  • Environmentally Safe and Tamper-Evident Built without hazardous materials and fully compliant with environmental safety standards—ideal for green logistics and regulatory-sensitive deployments.
