    1. 1. RFID Jeffrey Piontek Lead Instructional Technology Specialist Region 2 NYC Department of Education
    2. 2. What are RFID tags, and how do they work? RFID tags are electronic chips that emit radio signals. Tags can be active or passive. Often an RFID tag contains only a unique identifier although some may contain more information. Different tags transmit at a distance that may be limited to a fraction of an inch or extend to 1,500 feet. The system with which a tag communicates often creates and stores information about where a tag is, what time it passes a reader and may relate that information to a purchase or the movement of materials or people.
    3. 3. RFID  Who is using it? – Walmart – EZ Pass and SmartTag for toll roads – Exxon Speedpass – New car security systems – Agriculture – Libraries – Records Management
    4. 4. How does it work? • A tag is affixed to a resource. • The tag is programmed to be recognized by the system. • The tag can be scanned by a reader device to help manage the collection of resources.
    5. 5. Types of Tags Passive  No imbedded power source.  Weaker signal. Active  Imbedded power source.  Stronger signal.
    6. 6. Readers
    7. 7. Forward and Backward Channels
    8. 8. Hash-Based Access Control
    9. 9. Randomized Access Control
    10. 10. Silent Tree Walking
    11. 11. Educational Uses  Most widely known is the library  Textbook stores  Student Identification Cards  Meal Plans in colleges and universities
    12. 12. How are libraries using RFID?  Tags on books, videos, DVD/CD  Self-checkout  Automated book return  Automated sorting of books for large systems
    13. 13. Inventory Assistance  Use handheld equipment to inventory the collection or resources.  Find lost and misplaced books/files/boxes.
    14. 14. Handheld Devices
    15. 15. RFID – Policy Issues  Data Collection  Privacy Concerns  Public and staff education about the realities of RFID and how information will be used.
    16. 16. RFID - Cons  Expensive equipment and materials.  Difficulty reading tags.  Still a new technology – many issues with standards and security.
    17. 17. Cons continued…..  RFID tags: Big Brother in small packages  RFID Foes Find Righteous Ally  Used improperly, RFID has the potential to jeopardize     consumer privacy, reduce or eliminate purchasing anonymity, and threaten civil liberties.

    18. 18. RFID - Pros  Easier and faster inventory  Faster checkouts  Faster sorting – automated handling  Save staff time, repetitive tasks  Utilize staff on other projects & services
    19. 19. Future Applications          Maintaining shelf stocks in retail environments Tagging pets Proximity badges for building access Clothing – anti-forgery, customer returns Parenting logistics – Water park uses RFID bracelets to track children “Smart” appliances – Refrigerators that automatically create shopping lists – Ovens that know how to cook pre-packaged food “Smart” products – Clothing, appliances, CDs tagged for store returns “Smart” paper – Airline tickets that indicate your location in the airport – Library books – Business cards Recycling – Plastics that sort themselves
