Review of Various Aspects of Radio Frequency IDentification (RFID) Technology

Abstract

Radio Frequency Identification (RFID) is essentially a wireless method of identification of physically placed objects in a certain state space. It is the most emerging technology these days which is becoming the alternate for barcode. Hence this technology is receiving lot of attention comparatively over past few years. RFID technology is used to automatically identify any item or a package. Automatic identification can be done with the help of RFID Tags and RFID Reader units. An RFID tag contains the transponder that can transmit wireless information over short distance. This information is then received by the device called RFID Reader and further processed through middleware infrastructure. Billions of RFID tags are successfully installed worldwide. Tons of RFID Applications are being developed in the various fields like Healthcare, Engineering, Agri-food, Live-stocks etc. for traceability purpose. Familiarization with the benefit and the risk of RFID is important before using this technology. The shadow of this technology has made a huge impact on our daily lives. This text gives the brief review of RFID Technology with discussion on frequency ranges, standards, and applications with emerging innovations.
