RFID Guardian Use-Supply Chain

From RFID Wiki

The usage of RFID tags in military service and commerce is mostly related to supply chains. Although RFID technology improves e±ciency in military and business applications, it also has the potential danger of leaking information to unknown or even hostile readers. One proposal is to install RFID Guardians in transport vehicles, such as trucks, to prevent espionage in retail outlets or military supply chains.
