  • 1. RFIDName:Chan Yik YuID:12210692
  • 2. FutureIntroduction Survey development Applications Conclusion of RFID results and opportunities
  • 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
  • 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 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
  • 6. TYPES OF RFID TAGS Active Tags Semi-passive Tags Passive Tags• Use a battery • Contain built-in • Derive their power• communicate over batteries to power from the field distances of the chip’s generated by the several meters circuitry, resist reader interference and • without having an circumvent a lack active transmitter of power from the to transfer the reader signal due information stored to long distance. • They are different from active tags in that they only transmit data at the time a response is received
  • 7. APPLICATIONSFrequency of RFID tags in different applications Frequency Appx. Read Data Speed Cost of Application Range Tags Low Frequency <5cm Low High • Animal Identification (125kHz) (passive) • Access Control High Frequency 10 cm – 1m Low to Moderate Medium • Smart Cards (13.56 Mhz) to Low (passive) • Payment (paywave) Ultra High 3m -7m Moderate to High Low • Logistics and Supply Chain Frequency (433, 868-928 Mhz) (passive) • Baggage Tracking Microwave (2.45 & 10m -15m High High • Electronic toll collection 5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)
  • 8. CURRENT APPLICATIONS Application Segment Representative Competitive Current Typical Tag Type Applications Technologies Penetration Access Control Doorway entry Other keyless entry High Passive technologies Asset Tracking Locating tractors None Low Active within a freight yard Asset Tagging Tracking corporate Bar Code Low Passive computing systems Authentication Luxury goods Holograms Low Passive counterfeit prevention Baggage Tracking Positive bag Bar Code, Optical Low Passive matching Character Recognition POS Applications SpeedPass Credit Cards, Smart Medium Passive Cards, Wireless Phones SCM (Container Level) Tracking containers GPS-based Systems Low Active in shipping terminals SCM (Pallet Level) Tracking palletized Bar Code Minimal Active, Passive shipments SCM (Item Level) Identifying individual Bar Code Minimal Passive items Vehicle Identification Electronic toll Bar Code, License plate, Medium Active, Passive collection reader systems Vehicle Immobilizers Automotive ignition Other theft prevention High Passive systems technologies
  • 9. APPLICATIONSCredit Cards with RFID(Paywave function) Octopus (Smart Card)
  • 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_9N5UPRZuyuWt sk4
  • 12. SURVEY RESULT Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Security Customer Services 8% 5% Library Management Hotel Management 21% Other 5% 18% Banking and Finance 5% Pharmaceutic manufacturing industries Social Services Logistics and Supply Chain 15% 3% Management 20%
  • 13. FURTHER DEVELOPMENT In medical uses and library management

  • 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
