ISR’s Platform Aims to Expedite Shipping
A California company has announced a system for tagging cases and pallets of goods overseas, and for tracking and monitoring cargo in transit to the United States.
Aug 24, 2005—ISR Systems, a company based in Newport Beach, Calif., has announced a hardware, software and services platform called Trusted Shipper. The firm says this platform will enable manufacturers and shippers to add EPC tags to cases and pallets of goods at the source of manufacture, then track them while they are in transit and monitor their security.
RFID tags are read automatically when brought through an interrogation zone, rather than with the manual scanning required for bar codes. Therefore, tagged shipments will likely be received and processed at ports, distribution centers and warehouses further down the supply chain more quickly than those with just bar code IDs (as long as those ports, distribution centers and warehouses have the RFID hardware infrastructure needed to read those EPC tags). In addition, records of receipt for tagged goods will also likely be more accurate than those received through bar code scans, since the chance of error through manual scanning will be removed.
The Trusted Shipper system is comprised of the SupplyChain Guardian platform, which provides RFID tagging and an electronic manifest to satisfy the U.S. Department of Homeland Security's Container Security Initiative (CSI); and the Container Guardian platform, which allows users to track individual containers using a global positioning system (GPS), and to monitor the integrity of those containers, using RFID tags integrated with sensors. While the goods are in transit and within range of a GSM cell phone network, a general packet radio service (GPRS)—a packet-based wireless communication service for GSM cell phone networks—transmits location and sensor data to RFID Controller, a Java-based software application developed by ISR Systems. Since RFID Controller is Web based, ISR Systems staff can access it from any device linked to the Internet.
In SupplyChain Guardian, RFID Controller is used to generate and assign EPCs to goods and create advance shipment notices (ASNs) for retailers or the DOD in compliance with their individual RFID mandates. It also generates the electronic manifest that U.S. Customs requires 24 hours before any container is loaded onto a vessel.
Michael Skellern, CEO of ISR Systems' parent company, Universal Guardian, says Trusted Shipper customers begin the process by installing the RFID interrogators, printers and other RFID hardware and software necessary to tag cases and pallets of goods—including the RFID Controller application—within their overseas manufacturing facilities. When providing tagging services, ISR Systems will install Sato RFID printer-encoders and SAMSys RFID interrogators. Some manufacturers and suppliers, though, will likely prefer to maintain their own tagging operations, he says.
ISR Systems will generate an electronic manifest of all the goods once they are tagged. U.S. Customs requires this manifest 24 hours before any container is loaded onto a vessel for transport to the United States. This manifest will also be used to create an ASN, which will include the EPC data assigned to the cases and pallets of goods destined for retailers or the DOD.
To track a container’s location while it is in transit and GSM range, Container Guardian uses the T2 GPS tracker, an active RFID transponder integrated with a GPRS modem and a GPS receiver. If any of the sensors detect abnormal changes within a container while it is outside of GSM range, the T2 keeps a record of these changes and then transmits that info when the T2 is within range of a GSM network. According to David Hopps, ISR Systems vice president, the T2 is designed to function in dense environments, such as in ports or cities, where signal interference renders most GPS units inoperable. He says the T2 can also be used to track containers buried beneath as many as five other containers inside a ship—without the use of a signal repeater.
