Radio-frequency identification (RFID) uses electronic tags and labels to identify objects wirelessly over short distances. Discuss. Solution Please follow the data and description : RFID : This is the general abbrevation for the Radio-frequency identification (RFID). This is a regular and the widely used technology to record the presence of an object using radio signals. It is used for inventory control or timing sporting events. This is not a replacement for the process and the detection of the barcoding, but a complement or an substitute for the distant reading of codes apart form the barcoding technique. This technology is used for the automatic detection or an identification of a person, a package or an item based on the context. This is fulfilled with the use of the RFID tags. These are the small transponders that comprises of the combination of a radio receiver and the transmitter as well that will transmit and even used for the identity information over a short distance, when needed. The other piece to make use of RFID tags is an RFID tag reader. An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader. Most tags carry a plain text inscription and a barcode as complements for direct reading and for cases of any failure of radio frequency electronics. Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, that is used for the purpose of the modulating and de- modulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal. Uses : The uses of the tags include the : a) For the use of the objects and the goods in the malls. b) Robbery proof chips to avoid insecure entry for the users. c) Use of the safety products. d) In the stream of the health care. e) Tracking devices.
