Potential uses of embedded RFID in appliance identification.

Abstract

Radio Frequency Identification (RFID) has become a pervasive technology for the purpose of tracking goods through the supply chain. It is possible to adapt this radio technology such that remote identification is possible using the electrical power cable as a communication channel in place of the inductive coils used by most RFID tags. Furthermore, passive transponders which do not require a local power source may be used. This opens up several interesting possibilities for automatic appliance identification during manufacture, test and in general use.
