  1. Radio-Frequency Identification MBUS 626 IT Seminar Group 5 Kevin Frei Stephen Grant

  2. What is RFID? • RFID uses radios waves to exchange information between an electronic tag and a reader. • Tags can vary greatly in size. • Most RFID tags are passive.

  3. History of RFID Technology • Predecessors of RFID technology was used by the Allied Air Forces as far back as WWII • Early radar technologies could detect aircraft, but could not identify them • Encoded radio transponders would broadcast identification codes when activated

  4. Benefits • Decreased cost of equipment and tags • Decreased labor costs • Increased reliability • Real time tracking information • Improved logistical efficiency

  5. Current Uses for RFID • Product tracking • Biggest user of RFID technology today is the US Department of Defense • Animal identification • Electronic Passports and other important documents • Rapid-pay systems (EZ-Pass, Smartrip)

  6. Use of RFID in Automobiles • Zipcar • Parking Passes • Tolls • Traffic Management

  7. Mandates • Wal Mart and Target require that all primary suppliers use RFID for their products. • The US Department of Defense requires that all packages be marked with RFID tags.

  8. Potential Problems • Skimming • Eavesdropping • Privacy Concerns

  9. Costs and Challenges of RFID Implementation • High initial investment for broad applications • Marginal cost per tag is more than some alternatives • Security of sensitive information • The benefits over traditional barcode technology may not be great enough
