(June 3, 2011) - (RFID Journal) -

The GeoLok container security device can communicate its location and status through Wi-Fi, satellite and cellular communications, and can secure a cargo container's door so that it unlocks only where and when authorized to do so.

Prior to launching TrakLok in 2008, the founder of the company planned to develop an active RFID solution for tracking cargo transported by freight companies and steamship carriers. After speaking with potential end users,  the company's leadership instead decided to develop a container-locking device combining Wi-Fi-based RFID with GPS, satellite and cellular communication technologies, along with multiple sensors. The result is the GeoLok—a system that not only can determine where a container is located at any given time, but also prevent unauthorized access to cargo by clamping onto a shipping container's doors and keeping them locked until the proper code is entered at a predesignated location and time.
