2RADIO FREQUENCY IDENTIFICATION1. IntroductionRFID is an electronic device that is small in size. It contains a mini chip along with anantenna. It makes the use of electromagnetic field and radio frequency for automaticallyidentifying and tracking tags that are attached to the objects (Rajaraman, 2017). This report givesan overview about the RFID technology. It discusses about the use, working mechanism, typesand limitations of RFID technology.2. Working Mechanism of RFID RFID makes use of radio frequency and waves for reading, capturing and interacting withthe information that is stored on the tags of the objects (Hutter & Schmidt, 2013). The two maincomponents of RFID are the reader and the tag. Tag: The tag of RFID consists of a receiver as well as a transmitter. The tag consists ofan antenna for receiving and transmitting signals. It also consists of an integrated circuit for thepurpose of storing as well as processing information. The non-volatile memory of the tag caneither have programmable or fixed logic for the purpose of transmitting data.Reader: This consists of a two-way transceiver. It is also known as interrogator because itsends an encoded signal for interrogating the tag. Radio signal then activates the tags. Thetransponder of the tags converts radio signals into power for responding to the readers.

3RADIO FREQUENCY IDENTIFICATIONFigure 1: Simplified RFID System(Source: Created by author)2.1 Types of RFIDActive RFID: This type of RFID consists of internal source of power. It is dependent onthe battery. The power supplied by the battery can be used for generating signal on antenna andalso to power or charge the micro chip. It has the capability to read objects at a long distance. Ithas high data bandwidth as compared to passive RFID. It is responsible for initiatingcommunication. It is expensive and cannot operate without battery.Passive RFID: This type of RFID does not have any internal source of power. It does notrely on battery and has variety of sizes. It cannot be easily damaged in a harsh environmentunlike active RFID. The communication process is dependent on the size of the antenna and hereread range is considered to be limited.
