Defense Department Tests Hybrid Active/Passive RFID
Although more costly than passive RFID, active RFID work has already been integrated with anti-terrorist technologies such as radiological sensors. Big retailers like Wal-Mart and Target might someday follow suit, according to some.There is more to radio-frequency identification than the passive RFID that retailers are looking to deploy. The U.S. Department of Defense, in fact, is testing both typesactive and passivein the same supply chain applications. And some expect that big retailers such as Wal-Mart and Target will ultimately add active RFID to their now emerging passive RFID deployments. The Defense Department initially implemented active RFID for inventory control back in the early 1990s, after the first Persian Gulf War. Before that, military supply requisitions were placed either on paper or through EDI (electronic data interchange), often resulting in lost or incorrectly filled orders, said Bruce Jacquemard, executive vice president and general manager of global field operations for Savi Technology, a builder of RFID networks. The imminent RFID road ahead looks treacherous. Click here to read more.
The Defense Department currently uses Savis active RFID technology to track cargo shipments in 46 countries worldwide. Meanwhile, U.S. allies such as the United Kingdom and Denmark have started deploying Savis products in their own supply chains, Jacquemard said in an interview.
