ABSTRACT
RFID is the latest technology, which is a combination of both radio frequency based technology, and microchip technology. This paper poses the information about the origination and its peregrination since past 50 years. RFID has been around since World War II, however it was long considered too expensive and limited to be practical for many commercial applications until recently. The paper reviews bar coding and importance of RFID briefly. Preponderance and difficulties of RFID technology are also discussed. Most common frequency ranges of RFID technology along with their applications are tabulated in this paper. This paper also discusses a working model of the RFID with necessary images. The paper also throws light on the constructional features of RFID. This provides a non-technical operational overview about RFID. Consecutively, the operational characteristics of RFID are compared to other automatic identification technologies like biometrics and magnetic stripes. The images and the numerical results provide a detail description about the working system of RFID.
