  2. Introduction • Technology that uses electromagnetic waves • Exchange of data between terminal and object • Electronic tag attached to object • Involves interrogators (readers) and tags (labels). • RFID tags contain at least two parts: Integrated circuit and antenna • Integrated circuit for modulating and demodulating RF signal • Antenna for receiving and transmitting signal

  3. RFID TAG

  4. Working • Active, semi-active, and passive RFID tags • Composed of a microchip, antenna, and, in the case of active and semi-passive tags, a battery • Data­ stored within an RFID tag's microchip waits to be read. • The tag's antenna receives electromagnetic energy from an RFID reader's antenna. • Using power from its internal battery or power harvested from the reader's electromagnetic field, the tag sends radio waves back to the reader. • The reader picks up the tag's radio waves and interprets the frequencies as meaningful data. • Inductively coupled and capacitively coupled RFID tags aren't used as commonly today because they are expensive and bulky passive RFID tags.

  5. RFID Technology

  6. RFID

  7. Applications • Walmart- Largest retailer adopts RFID technology • Used in enterprise supply chain management • Improve the efficiency of inventory tracking and management. • Provide real-time information • Manufacturers to get better readings of customers • Improved supply chains

  8. Current uses • Decreased cost of equipment and tags • Increased performance to a reliable 99.9% • A stable international standard around UHF passive

  9. Payment by Mobile Phones • When inserted into a mobile phone, the microSD card can be both a passive tag and an RFID reader • After inserting the microSD, a user's phone can be linked to bank accounts and used in mobile payment. • Credit card information can be stored, and bank accounts can be directly accessed using the enabled handset. • The phone, if used as a vector for mobile payment, has added security in that users would be required to enter a passcode or PIN before payment is authorized

  10. Transportation Payments • Governments use RFID applications for traffic management • Automotive companies use various RFID tracking solutions for product management • Car-sharing : The Zipcar car-sharing service uses RFID cards for locking and unlocking cars and for member identification

  11. Season parking tickets • Housing & Development Board (HDB) Singapore called two tenders in 2006 to implement RFID to replace the paper Season Parking Ticket (SPT). The successful tenderers have distributed RFID tags to SPT holders since March 2007

  12. RFID ecosystem

  13. Toll roads • RFID is being used for e–tolling in Motorways • In Dubai, UAE, RFID is being used for e–tolling • In Turkey, RFID has been used in the motorways and bridges as a payment system • In Ireland, the eToll system uses RFID tags for payments on all road tolls, including the barrier-free • RFID tags are used for electronic toll collection at toll booths

  14. Public transit (bus, rail, subway) • RFID passes are used for public transport systems throughout Europe. • Can also be used in most convenience stores and vending machines in subways as cash • Allows the user to credit money in advance and to be debited according to the distance travelled, as determined by the check-in and check-out stations. • RFID operated cards as fare collection

  15. RFID TAGS-ELECTRONIC TOLL COLLECTION

  16. Asset management and retail sales • RFID combined with mobile computing and provide a way for organizations to identify and manage their assets • Give proof of identification and attendance • Eliminates manual data entry • Organizations are already using RFID tags combined with a mobile asset management solution to record and monitor the location of their assets, their current status, and whether they have been maintained. • Item-level retail uses leading to efficiency and product availability gains

  17. Product tracking • Product tracking applications • Begins with plant-based production processes • Extends into post-sales configuration management policies for large buyers

  18. IT asset tracking • High-frequency RFID or HFID/HighFID tags are used in library book or bookstore tracking, jewelry tracking, pallet tracking, building access control, airline baggage tracking, and apparel and pharmaceutical items tracking. • Deliver an integrated supply chain, from warehouse to consumer. • Commercially in pallet and shipping container tracking, and truck and trailer tracking in shipping yards

  19. Transportation and logistics • Yard management, shipping and freight and distribution centers • Locomotives and rolling stock are equipped with two passive RFID tags • The data encoded on each tag identifies the equipment owner, car number, type of equipment, number of axles, etc • Derive further data about the physical characteristics of car inventory database and the railroad's own database indicating the lading, origin, destination, etc. of the commodities being carried

  20. Animal identification • RFID tags for animals represent one of the oldest uses of RFID technology • RFID has become crucial in animal identification management. • An implantable variety of RFID tags or transponders can also be used for animal identification. The transponders are more well-known as passive RFID technology, or simply "chips" on animals

  21. Inventory systems • Accurate knowledge of the current inventory • Reduction of labor costs • The simplification of business processes • Reduction of inventory inaccuracies • Help organizations track and audit their records • To support compliance with regulations

  22. Hospital operating rooms • The system, consisting of an electronic reader and high frequency RFID-tagged disposable gauze, sponges, and towels, is designed to improve patient safety and efficiency • The system automatically provides a device-reconciled count by directly matching the unique identifier on each tagged item both entering into and then out of the surgical case

  23. Promotion tracking • Manufacturers are exploring the use of RFID tags on promoted merchandise so that they can track exactly which product has sold through the supply chain at fully discounted prices.

  24. Libraries • The RFID tag can contain identifying information, such as a book's title or material type, without having to be pointed to a separate database • It can also act as a security device, taking the place of the more traditional electromagnetic security strip • RFID tags can be read through an item, there is no need to open a book cover or DVD case to scan an item • RFID tags can also be read while an item is in motion, using RFID readers to check-in returned items while on a conveyor belt reduces staff time

  25. Library RFID system

  26. Potential uses • Access management • Tracking of goods and RFID in retail • Tracking of persons and animals • Toll collection and contactless payment • Machine readable travel documents • Tracking sports memorabilia to verify authenticity • Airport baggage tracking logistic

  27. Problems and concerns • Data flooding: Each tag generating a message each time when passing a reader may be a desired outcome. Event filtering is required to reduce this data inflow to a meaningful depiction of moving goods passing a threshold. Various conceptshave been designed, performing the filtering from noisy and redundant raw data to significant processed data.

  28. Problems and concerns • Global standardization: No emerging standard has yet become as universal as the barcode • Security concerns : A primary RFID security concern is the illicit tracking of RFID tags • Tags, which are world-readable, pose a risk to both personal location privacy and corporate/military security • Temperature Exposure : RFID tags are created by gluing an integrated circuit (IC) to an inlay. This poses a problem as vibration and high temperatures will loosen the connection. If the IC loses connection with the inlay, the RFID tag will no longer transmit
