Rfid applications

  1. 1. 10/18/2012RFID APPLICATIONS
  2. 2. WORKFLOWIntroduction Survey Future Applications Conclusion of RFID Results development
  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
  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
  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
  6. 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 the from the field distances of several chip’s circuitry, resist generated by the meters interference and reader circumvent a lack of • without having an power from the reader active transmitter to signal due to long transfer the distance. information stored • They are different from active tags in that they only transmit data at the time a response is received
  7. 7. APPLICATIONSFrequency Appx. Read Data Speed Cost of Application Range TagsLow Frequency <5cm Low High • Animal Identification(125kHz) (passive) • Access ControlHigh Frequency 10 cm – 1m Low to Mediu • Smart Cards(13.56 Mhz) Moderate m to (passive) • Payment (paywave) LowUltra High 3m -7m Moderate to Low • Logistics and SupplyFrequency (433, High Chain (passive)868-928 Mhz) • Baggage TrackingMicrowave (2.45 10m -15m High High • Electronic toll collection& 5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)
  8. 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 Tracking containers GPS-based Systems Low Active Level) in shipping terminals SCM (Pallet Level) Tracking palletized Bar Code Minimal Active, Passive shipments SCM (Item Level) Identifying Bar Code Minimal Passive individual 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

  11. 11. ONLINE SURVEY Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuy uWtsk4
  12. 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% Hotel Management Library Management Other 5% 21% 18% Banking and Finance 5% Pharmaceutic manufacturing industries Logistics and Supply Social Services 15% Chain Management 3% 20%
  13. 13. FURTHER DEVELOPMENT In medical uses and library management
  14. 14. VIDEO
  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
