  1. 1. C RFID & ITS APPLICATION Members: Lily Chang(14250128) River Liu(15250474) GCIT1015
  2. 2. FLOW OF PRESENTATION Thursday, October 15, 2015 RFID & its applications 2
  3. 3. RFID • RFID = Radio Frequency Identification • Electronic labeling and wireless identification of objects using radio frequency • Tag carries with its information • a serial number • Model number • Color or any other imaginable data • When these tags pass through a field generated by a compatible reader, they transmit this information back to the reader, thereby identifying the object Thursday, October 15, 2015 RFID & its applications 3
  4. 4. RFID components • A basic RFID system consists of these components: • A programmable RFID tag/inlay for storing item data; • Consisting of an RFID chip for data storage • an antenna to facilitate communication with the RFID chip • A reader/antenna system to interrogate the RFID inlay • Application software and a host computer system Thursday, October 15, 2015 RFID & its applications 4
  5. 5. RFID Tag • The RFID tag consists of an integrated circuit (IC) embedded in a thin film medium. • Information stored in the memory of the RFID chip is transmitted by the antenna circuit embedded in the RFID inlay via radio frequencies, to an RFID reader • 3 types • Passive • Semi-passive • Active Thursday, October 15, 2015 RFID & its applications 5
  6. 6. Types of RFID Tags Active Tags • Use a battery • communicate over distances of several meters Semi-passive Tags • Contain built-in batteries to power the chip’s circuitry, resist interference and circumvent a lack of power from the reader signal due to long distance. • They are different from active tags in that they only transmit data at the time a response is received Passive Tags • Derive their power from the field generated by the reader • without having an active transmitter to transfer the information stored Thursday, October 15, 2015 RFID & its applications 6
  7. 7. Applications Thursday, October 15, 2015 RFID & its applications 7 Frequency Appx. Read Range Data Speed Cost of Tags Application Low Frequency (125kHz) <5cm (passive) Low High • Animal Identification • Access Control High Frequency (13.56 Mhz) 10 cm – 1m (passive) Low to Moderate Medium to Low • Smart Cards • Payment (paywave) Ultra High Frequency (433, 868-928 Mhz) 3m -7m (passive) Moderate to High Low • Logistics and Supply Chain • Baggage Tracking Microwave (2.45 & 5.8 Ghz) 10m -15m (passive) 20m – 40m (active) High High • Electronic toll collection (Autotoll) • Container Tracking
  8. 8. Current Applications Thursday, October 15, 2015 RFID & its applications 8
  9. 9. Applications Credit Cards with RFID (Paywave function) Thursday, October 15, 2015 RFID & its applications 9 Octopus (Smart Card)
  10. 10. Applications Autotoll (Electronic toll collection) Thursday, October 15, 2015 RFID & its applications 10 Access Control
  11. 11. Online Survey • Target: SME • Information: Opinion on RFID and its applications • Site: • http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4 Thursday, October 15, 2015 RFID & its applications 11
  12. 12. Survey Result Thursday, October 15, 2015 RFID & its applications 12 Education 6% Manufacturing 23% Retailing 24% Warehousing 29% Transportation 6% Others 12% TYPES OF THE COMPANIES ANSWERSING THE QUESTIONNAIRE
  13. 13. Further Development • In medical uses and library management Thursday, October 15, 2015 RFID & its applications 13
  14. 14. Video Thursday, October 15, 2015 RFID & its applications 14
  15. 15. Conclusion • Positive • RFID is a contactless reading technology and can read through other materials • Hold more data than barcode does • RFID tags data can be changed or added • More effective, bring lots of convenience to us • Negative • Cost is relatively remain high (compare to barcode) • RFID signals may have problems with some materials • RFID standards are still being developed Thursday, October 15, 2015 RFID & its applications 15
