ABSTRACT

Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. One of the two main parts is an integrated circuit for storing and processing information, modulating and demodulating a (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal. A technology called chip less RFID allows for discrete identification of tags without an integrated circuit, thereby allowing tags to be printed directly onto assets at a lower cost than traditional tags.

Passive RFID tags have no internal power supply. The minute electrical current induced in the antenna by the incoming radio frequency signal provides just enough power for the CMOS integrated circuit in the tag to power up and transmit a response. Most passive tags signal by backscattering the carrier wave from the reader.

Active RFID tags have their own internal power source, which is used to power the integrated circuits and broadcast the signal to the reader. Active tags are typically much more reliable than passive tags due to the ability for active tags to conduct a session with a reader.

Our research is focused on the use of embedded RFID modules, more specifically self powered passive RFIDs in human beings. Integration of smart cards in embedded RFID modules so as to implement automatic payment methods, individual tracking mechanism, use of auxiliary power source for active RFID modules and remote health monitoring. It also deals with the risks associated with this technique like radiations, biological reactions and etc...
