  1. 1. RFID Technology… Trends and Challenges April 2006 By Nalini Mahadeo RFID Technology… Opportunities and challenges
  2. 2. Objectives <ul><li>To educate, inform and share information on a rapidly growing technology. </li></ul><ul><li>To create a forum for discussion. </li></ul><ul><li>To facilitate development of a network amongst RFID stakeholders. </li></ul>
  3. 3. Overview <ul><li>RFID History </li></ul><ul><li>RFID system components </li></ul><ul><ul><li>Tags, Readers, Spectrum, Antennas </li></ul></ul><ul><li>RFID Models </li></ul><ul><li>Regulatory Considerations </li></ul><ul><li>Market Trends </li></ul><ul><li>Challenges </li></ul><ul><ul><li>Standards, Security, Privacy, Societal impact </li></ul></ul>
  4. 4. What is RFID? <ul><li>Radio Frequency Identification or RFID refers to the set of technologies that use radio waves for identifying objects or people. </li></ul>Identification System Wireless Link ) ) ) ) ) ) ) ) ) ( ( ( ( ( ( ( ( ( Item to identify
  5. 5. RFID Characteristics <ul><li>Does not require line of sight </li></ul><ul><li>Can withstand harsh environments </li></ul><ul><li>Can be reused </li></ul><ul><li>Can be read in groups </li></ul><ul><li>Allows for data security </li></ul>
  6. 6. RFID History
  7. 7. <ul><li>Three Main Components: </li></ul><ul><li>Tags (or transponders) - carry identifying data </li></ul><ul><li>Readers (or transceivers) - read/write tag data & interfaces with system </li></ul><ul><li>Back-end infrastructures - process the data </li></ul>RFID Basics RS485 Serial Interface Computer ID Tag Reader
  8. 8. RFID System: Components
  9. 9. Readers <ul><li>Communicate with RFID tags. </li></ul><ul><li>Also called an interrogator because it “interrogates&quot; the tag. </li></ul>
  10. 10. Radio Modules and Readers
  11. 11. Tags <ul><li>Passive Tags </li></ul><ul><li>Semi-Passive Tags </li></ul><ul><li>Active Tags </li></ul>
  12. 12. Tag Types > 7 TTD > 0.7 TTD > 37 TTD Price < 150 ft 4” - 15ft ~ 300ft Distance Yes (not used for communication) No Yes (used for communication) Battery Semi-Passive Passive 67% (2004) Active 33% (2004)
  13. 13. Tags- Passive
