Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically-stored information.  RFIDRFID device must be scanned to retrieve the identifying information. — Radio-Frequency Identification — provides a unique identifier for that object and just as a bar code or magnetic strip the An RFID system has three parts: A scanning antenna A transceiver with a decoder to interpret the data A transponder the RFID tag – that has been programmed with information An RFID reader is a network connected device (fixed or mobile) with an antenna that sends power as well as data and commands to the tags. The RFID reader acts as an access point for RFID tagged items so that the tags’ data can be made available to business applications. Tag Antenna Tag antennas collect energy and channel it to the chip to turn it on. Tag antennas can be made from a variety of materials; they can be printed, etched, or stamped with conductive ink, or even vapor deposited onto labels Reader AntennaReader antennas convert electrical current into electromagnetic waves that are then radiated into space where they can be received by a tag antenna and converted back to electrical current. RFID Use in Railway The Indian Railways will use radio-frequency identification tags (RFID) for tracking of wagons, coaches and locomotives to ensure effective and transparent functioning. There are about 2.25 lakh wagons, 50,000 coaches and 9,000 locomotives in the railways. Railways have sanctioned Rs 57 crore for the first phase of rollout of the system. The tag designed by the Centre for Railway Information System (CRIS) is estimated to cost Rs 1000 per tag. At the time of wagon condemnation, RFID tags have to be removed and can be reused as they have a life of 25 years. Henceforth it would be a standard practice for all new wagons coming out of manufacturing units to be equipped with RFID tags. Railways had implemented the RFID system on the Vishakhapatnam-Talcher-Paradeep section as a pilot project. in the 1990s the Association of American Railroads (AAR) adopted his RFID system as industry standard. “The RFID systems for rail in North America use frequencies near 915MHz.” rfid,technology,communications,scanner,radio waves,barcode,supermarkets,chips,implantation,how rfid works,what is rfid,radio frequency identification,waves,wireless communications,tagging,tags,rfid in action,rfid examples,seminar,topic,latest technology,explained What is RFID what is its use in railway , retail market ,transportation, sports ,health , automobile industries and medical science
