Radio Frequency Identification (RFID)

This overview of Radio Frequency Identification (RFID) technology explains its key components, including microchips, readers, and transceivers. Discover how RFID works step by step: from the reader emitting energy to the tag receiving it, and how information is processed and stored in databases. Explore the advantages and disadvantages of RFID systems, including their applications in enhanced driver’s licenses and surveillance. Also, learn about privacy concerns, reliability issues, and the potential for technology malfunction.

  2. How RFID Works 1. Microchip= information 2. Reader emits energy, tag receives energy Clipart Clipart Clipart http://readwrite.com/files/files/files/rfid%252520scanner.jpg

  3. How RFID Works 3. Battery/radio energy 4. Microchip radio waves create information. Clipart Clipart Clipart

  4. How RFID Works 5. Reader intercepts waves. 6. Reader interprets waves to info. http://readwrite.com/files/files/files/rfid%252520scanner.jpg Clipart Clipart

  5. RFID Parts • Scanning antenna • Transceiver • RFID Tag • RFID Scanner Clip Art

  6. Scanning Antenna • Input/output device • Receives signals, like radio waves http://www.ebay.co.uk/itm/Miniscan-Mobile-Scanner-Receiver-Mag-Antenna-0-1300MHz-BNC-Aerial-/330865859391?pt=UK_Mobile_Phones_Communication_Radio_Antennas&hash=item4d09245b3f

  7. Transceiver • Input/output device • Transmitter+receiver http://img.directindustry.com/images_di/photo-g/rfid-transceiver-34006-2767833.jpg

  8. RFID Tag • Input/Output • Microchip w/ an antenna • Unique serial number http://philosophers-stone.co.uk/wordpress/2013/08/california-wants-to-implement-enhanced-drivers-licenses-that-use-radio-tracking-beacons/

  9. RFID Reader • Processing Device • Directs other hardware. • Uses information. http://readwrite.com/files/files/files/rfid%252520scanner.jpg

  10. Database Software • Stores information • Necessary for signal meaning • Human interaction • Many kinds http://decentralist.files.wordpress.com/2012/06/ms-excel.png

  11. Kernel Database Software http://www.filebuzz.com/software_screenshot/full/114867-Microsoft_SQL_Recovery.gif

  12. Enhanced Driver’s Licenses • RFID • Passport/license • DHS database • Usage Clip Art

  13. Department of Homeland Security • Advantage: Money and time • Scanning • Non-stop • Personnel http://bosmun.org/wp-content/uploads/2012/06/Department-of-Homeland-Security-logo.png

  14. Department of Homeland Security • Disadvantage: Technology dependence, malfunction.

  15. Clip Art Drivers • Advantage: Quick travel, pre-paid. • Disadvantage: Malfunction worsen time issue. Clip Art

  16. Privacy and Anonymity • Location tracking • Private information • Easy with scanner http://www.thechurchofnopeople.com/wp-content/uploads/2012/06/big-brother-poster.jpg

  17. Surveillance • Object tracking • Human behavior • EDL with DHS http://politicalcontext.org/wp-content/uploads/2013/06/surveillance_big.gif

  18. Reliability and Integrity • Update failure • Human error • Some RFID re-written https://itgs-jhs.wikispaces.com/1.1+Reliability+%26+Integrity
