Royal Food Import Expects E-Seals Will Save It a King's Ransom

The food importer will soon begin using Savi Networks cargo container seals to track the location and temperature of products being transported from factories overseas to stores in the United States.

Once the seal is locked, it begins transmitting its unique ID number via a cellular connection, to cellular antennas in the vicinity. (The seal can be set to deactivate while at sea and not within range of a cell tower, in order to conserve battery life.) It also sends its longitude and latitude, based on GPS data, as well the temperature and humidity within the container. If the humidity or temperature falls outside the acceptable threshold, or if the seal detects movement that could indicate a security breach, it transmits an alert.

During the test, Tuthill says, the containers sent information from the point of manufacture, where the container was loaded with packaged food, as well as en route to the seaport and at the port itself. Its signal fell outside of cellular range while at sea, but was picked up again upon reaching the U.S. port. At that time, had there been any alerts indicating problems while the container was at sea, Royal Food would have been notified.


Data transmitted by the cargo seals is managed by the SaviTrak control center.

Data transmitted by the cargo seals is forwarded to the Savi Networks Web-based server, where it is managed by the SaviTrak control center. Royal Food can then access that information via the Internet, after providing the proper password. The SaviTrak software can also forward alerts to the company's staff by e-mail or text message.

Royal Food (which pays Savi Networks a monthly fee for the service) also makes this data available to its customers. The system can be set to issue an alert to the food importer, or to its customers, if the container reaches a specified location, thus indicating it will soon arrive at the rail yard, where it needs to be unloaded. At that point, Royal Food can then pay for the shipment and send a truck to pick up the approaching container. For the company's customers, the benefit is in knowing where their products are, and thus being better able to predict the date and time of their arrival at stores or distribution centers.

"We provide SaviTrak as a full service," Smith states, meaning that not only does Savi Networks host the Web-based service, it also manages the container seals. When Royal Food removes the seals to unload the containers, it places them in a box provided by Savi Networks and ships them back, so that Savi Networks can later redistribute the seals where needed.

According to Tuthill, the benefits have been threefold. "If you can shave two or three days [per shipment] out of the equation, that can save hundreds of thousands of dollars," he says. The system also provides safety by sending an alert if the seal has been tampered with. "The safety aspect is extremely important—that's the driving force for me." The system can offer customers assurance that no one has tampered with a container while it is in transit, he says, adding that the temperature data is important to perishable products that might be sensitive to extreme heat or cold. "So if there is an extreme temperature discovered on the vessel," the products can be moved forward to be shipped immediately by rail.

Tuthill says he passes the system's cost on to those customers who request access to the data, as part of the fee for his company's service. The increase in cost, he notes, is minor. The food-processing plants that produce Royal Food products will soon begin attaching Savi Networks LSE seals to hundreds of containers, Tuthill says, and the system is expected to go live in late March or early April of this year.
