Savi Technology and OneSeal A/S are planning to jointly develop and market a disposable low-cost electronic bolt seal for intermodal containers that automatically transmits alerts over radio frequencies when locking mechanisms on cargo containers are tampered with or violated.

The new electronic seal will combine EchoPoint, Sunnyvale, CA-based Savi's active radio frequency identification (RFID) technology, with Denmark-based OneSeal's high-security locks.

The companies plan to introduce a locking seal in the $10 range by early next year to improve the security of cargo containers moving worldwide by ship, rail and truck. Savi noted that this electronic seal is being designed for use in conjunction with its SmartChain and Transportation Security System tracking software.
