Reusable TrailerSeal Combines GPS, RFID, and GPRS in One Mobile, Battery-Powered Unit

EarthSearch Communications, (“EarthSearch”) has launched its latest product integrating RFID and GPS at the hardware level: TrailerSeal. An innovative mechanical, battery-powered, reusable padlock, TrailerSeal is embedded with RFID, GPS, and GPRS for remote container tracking, all in one unit. Using built-in business logic and intelligence, TrailerSeal secures shipping containers, whether in transit or at rest, by providing continuous visibility of RFID tagged assets, in addition to tracking the container.

TrailerSeal is able to provide continuous, real-time visibility of assets and container by transmitting event and location information to EarthSearch’s proprietary web-based software platform, GATIS. EarthSearch’s Global Asset Tracking & Identification System (GATIS) is a web-based RFID-centric enterprise-class solution which leverages an integrated Geographic Information System (GIS) solution with GPS and RFID data. It combines these with other sensor technologies for a complete real-time asset and business management solution. As the software side of TrailerSeal, GATIS features an advanced user interface that is easily accessible via most web browsers. TrailerSeal communicates with GATIS to manage remote events and to translate data based on user defined business logic.

TrailerSeal records and transmits every location and event and sends alerts of undesignated stops or trailer access by a driver or unauthorized access to a container in a shipyard environment. Powered by rechargeable lithium batteries capable of lasting up to 90 days, TrailerSeal can be programmed to communicate each hour of the day and will send notifications in the case of event triggered alerts. The embedded RFID allows shippers to store data about the cargo in the device, allowing TrailerSeal to log activities related to the cargo that can be transmitted to GATIS in real-time, giving up-to-date access to cargo manifests.
