  • 1. RFID APPLICATIONS FRIDAY,OCTOBER 19,2012
  • 2. WORKFLOW
  • 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, theytransmit this information back to the reader, thereby identifying the object
  • 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
  • 5. RFID TAG The RFID tag consists of an integrated circuit (IC) embedded in athin film medium. Information stored in the memory of the RFID chip is transmitted bythe antenna circuit embedded in the RFID inlay via radio frequencies, toan RFID reader 3 types • Passive • Semi-passive • Active
  • 6. TYPES OF RFID TAGS Active Tags Semi-passive Tags Passive Tags•Use a battery •Contain built-in •Derive their•communicate batteries to power from the over distances of power the chip’s field generated several meters circuitry, resist by the reader interference and •without having circumvent a lack an active of power from transmitter to the reader signal transfer the due to long information distance. stored •They are different from active tags in that they only transmit data at the time a response is received
  • 7. Frequency APPLICATIONS Appx. Read Range Data Speed Cost of Tags ApplicationLow Frequency <5cm Low High • Animal Identification(125kHz) (passive) • Access ControlHigh Frequency (13.56 10 cm – 1m Low to Moderate Medium to • Smart CardsMhz) Low (passive) • Payment (paywave)Ultra High Frequency 3m -7m Moderate to High Low • Logistics and Supply Chain(433, 868-928 Mhz) (passive) • Baggage TrackingMicrowave (2.45 & 5.8 10m -15m High High • Electronic toll collection (Autotoll)Ghz) (passive) • Container Tracking 20m – 40m (active)

  • 10. APPLICATIONSAutotoll (Electronic toll collection) Access Control
  • 11. ONLINE SURVEY Target: SME Information: Opinion on RFID and its applications Site: • http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4
  • 12. SURVEY RESULTTypes of the companies answersing the questionnaire 12% 6% Education 6% 23% Manufacturing Retailing Warehousing Transportation Others29% 24%
  • 13. FURTHER DEVELOPMENT In medical uses and library management

  • 15.  Positive CONCLUSION • 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
