Radio Frequency Identification (RFID) is a technology that uses radio frequencies to automatically identify and track people or objects.
Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a (RF) signal and can also be used for other specialized functions. The second is an antenna for receiving and transmitting the signal. There are many application areas that could be enabled by RFID, high level solution architecture of integrating RFID with an existing Automation/Health care/Transportation to deliver interesting converged applications. The latest technology on RFID is Electronic RFID Lock.
