    Rfid Work   Without Video Rfid Work Without Video Presentation Transcript

    • * Presented By : Naval Kush, E&C Engineering, 6th Semester, Ishwarchand Vidyasagar Institute of Technology, Mathura
    • * Radio-frequency identification (RFID) is the use of a wireless non-contact system that uses radio- frequency electromagnetic fields to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking. Some tags require no battery and are powered by the electromagnetic fields used to read them. Others use a local power source and emit radio waves (electromagnetic radiation at radio frequencies).* The tag contains electronically stored information which can be read from up to several metres (yards) away. Unlike a bar code, the tag does not need to be within line of sight of the reader and may be embedded in the tracked object. *
    • * RFID chip next to a grain of rice. RFID chips contain a radio-frequency electromagnetic field coil that employs a magnetic field to emit a coded identification number when queried by a reader device.
    • * A radio-frequency identification system uses tags, or labels attached to the objects to be identified. Two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response. The readers generally transmit their observations to a computer system running RFID software or RFID middleware.* The tags information is stored electronically in a non-volatile memory. The RFID tag includes a small RF transmitter and receiver. An RFID reader transmits an encoded radio signal to interrogate the tag. The tag receives the message and responds with its identification information. This may be only a unique tag serial number, or may be product-related information such as a stock number, lot or batch number, production date, or other specific information. *

    • * RFIDs are easy to conceal or incorporate in other items. For example, in 2009 researchers at Bristol University successfully glued RFID micro-transponders to live ants in order to study their behavior. This trend towards increasingly miniaturized RFIDs is likely to continue as technology advances.* Hitachi holds the record for the smallest RFID chip, at 0.05mm × 0.05mm. This is 1/64th the size of the previous record holder, the mu-chip. Manufacture is enabled by using the silicon- on-insulator(SOI) process. These dust-sized chips can store 38- digit numbers using 128-bit Read Only Memory(ROM). A major challenge is the attachment of the antennas, thus limiting read range to only millimeters. *
    • * Payment by mobile phones Since summer 2009, two credit card companieshave been working with Dallas, i.e. Dairy Queen & 7-Eleven, Texas-based Device Fidelity to developspecialized micro SD cards. When inserted into amobile phone, the micro SD card can be both apassive tag and an RFID reader. After inserting themicro SD, a users phone can be linked to bankaccounts and used in mobile payment *
    • * Inventory systems An advanced automatic identification technologybased on RFID technology has significant value forinventory systems. The system can provide accurateknowledge of the current inventory as per anacademic study performed at Wal-Mart.In 2004, Boeing integrated the use of RFID technologyto help reduce maintenance and inventory costs onthe Boeing 787 Dreamliner. *
    • * Product tracking RFID use in product tracking applications begins with plant-based production processes, and then extends into post-sales configuration management policies for large buyers. In 2005, the Wynn Casino, Las Vegas, began placing individualRFID tags on high value chips. These tags allowed casinos theability to detect counterfeit chips, track betting habits ofindividual players, speed up chip tallies, and determine countingmistakes of dealers. In 2010, the Bellagio casino was robbed of$1.5 million in chips. The RFID tags of these chips wereimmediately invalidated, thus making the cash value of thesechips $0. *
    • * Passports The first RFID passports ("E-passport") were issuedby Malaysia in 1998. In addition to information also contained onthe visual data page of the passport, Malaysian e-passports recordthe travel history (time, date, and place) of entries and exits fromthe country. Other countries that insert RFID in passports include Norway(2005), Japan (March 1, 2006), most EU countries (around 2006)including Spain, Ireland and the UK, Australia, Hong Kong and theUnited States (2007), Serbia (July 2008), Republic of Korea (August2008), Taiwan (December 2008), Albania (January 2009), ThePhilippines (August 2009), Republic of Macedonia (2010). *
    • * Identification RFID tags for animals represent one ofthe oldest uses of RFID technology.Originally meant for large ranches andrough terrain, since the outbreakof mad-cow disease, RFID has becomecrucial in animalidentification management.An implantable RFID tag ortransponder can also be used for animalidentification. The transponders aremore well-known as passive RFIDtechnology, or "chips" on animals.The Canadian Cattle IdentificationAgency began using RFID tags as areplacement for barcode tags. *
    • * RFID can be used in a variety of other applications, such as:* Access management* Tracking of goods* Tracking of persons and animals* Toll collection and contact-less payment* Machine readable travel documents* Tracking sports memorabilia to verify authenticity* Airport baggage tracking logistics *
    • * As from the previously presented data, it is rather more obvious to accept that RFID is a much important growing technology, and it can be viewed as a remarkable landmark in the field of identification systems as well as in defense systems terminology for security and access systems to remotely locked red alert areas, to access the authorized personnel’s identity and to prevent any breakthrough in the security, and much more.* So we can say, RFID could prove to be a boom to the ID technologies in the forthcoming future. *
