March 17 RFID Presentation

  1. 1. TAG You're IT! - Radio Frequency IDentification (RFID) in Action Stuart Pothan – Industry Leader Supply Chain Andrew Ly – Application Server Architect
  2. 2. Contents <ul><li>What is it? </li></ul><ul><li>Trends </li></ul><ul><li>Inside Tags and Readers </li></ul><ul><li>RFID Architectures and Infrastructure </li></ul><ul><li>Barcode vs. RFID </li></ul><ul><li>RFID Standards </li></ul><ul><li>Applications and Challenges </li></ul><ul><li>The Future </li></ul><ul><li>Demo </li></ul>
  3. 3. What is it? <ul><li>Radio frequency identification (RFID) is a wireless automatic data capture (ADC) technology that comprises small data-carrying transponders ('tags'), and fixed or mobile scanners ('readers'). Tags are attached to or embedded in objects to be identified. </li></ul>
  4. 4. Trends
  5. 5. How it works <ul><li>RFID tag: Integrated Circuit + antenna. The data is stored on the IC (~2Kb). $0.50 </li></ul><ul><li>Information is sent to and read from RFID tags over RF signals. </li></ul><ul><li>An RFID reader captures the data and passes it on to computers through cable or wireless network (Wi-Fi or Bluetooth) </li></ul>
  6. 6. Tag Properties <ul><ul><li>Invisible: As small as 0.4mm x 0.4mm, and thin enough to be embedded into paper </li></ul></ul><ul><ul><li>Can be read without line of sight of the item </li></ul></ul><ul><ul><li>Passive (no battery) or Active (has battery) </li></ul></ul><ul><ul><li>Tag memory properties: </li></ul></ul><ul><ul><ul><li>Read-only </li></ul></ul></ul><ul><ul><ul><li>Write Once Read Many times (WORM) </li></ul></ul></ul><ul><ul><ul><li>Read and write </li></ul></ul></ul><ul><ul><ul><li>64 – 256 bits of data </li></ul></ul></ul><ul><ul><li>Frequency - Maximum Read Range </li></ul></ul><ul><ul><ul><li>Low Frequency-10 inches (254 mm) </li></ul></ul></ul><ul><ul><ul><li>High frequency-3 feet (1 meter) </li></ul></ul></ul><ul><ul><ul><li>Ultra-high frequency (UHF) -(* required by Wal-Mart) up to 30 feet (<10 meters) </li></ul></ul></ul>
  7. 7. Inside the Tag
  8. 8. EPC Global RFID Tag Classes
  9. 9. Generation 2 Tags <ul><li>The next generation of EPC protocol is better for three primary reasons: </li></ul><ul><ul><li>It creates an interoperable, global standard, </li></ul></ul><ul><ul><li>There are additional features making it technically more advanced, </li></ul></ul><ul><ul><li>It uses more advanced anti-collision protocols for faster, more accurate performance. </li></ul></ul><ul><li>The Class1 Generation 2.0 protocol will be backward compatible for Generation 1.0 Class 1 and Class 0 </li></ul><ul><li>Generation 2.0 protocol will also operate with the emerging ISO18000-6 standard protocol </li></ul>
  10. 10. Readers Properties <ul><ul><li>Retrieve data from tags </li></ul></ul><ul><ul><li>Stationary or portable </li></ul></ul><ul><ul><li>10 to 800 tags per second </li></ul></ul><ul><ul><li>Price: $2000 - $3000 (dropping to $100) </li></ul></ul>10BaseT Ethernet Bluetooth IEEE 802.11 (WiFi) RS-232
