Transcript

  • 1. WORKFLOW FutureIntroduction Survey development of REID Applications Conclusion Results and opportunities
  • 2. RFIDRFID = Radio Frequency IdentificationElectronic labeling and wireless identification of objects using radio frequencyTag carries with its information a serial number Model number Color or any other imaginable dataWhen these tags pass through a field generated by a compatible reader, they transmit this information back to the reader, thereby identifying the object
  • 3. RFID COMPONENTSA 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 chipA reader/antenna system to interrogate the RFID inlayApplication software and a host computer system
  • 4. RFID TAGThe 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 reader3 types Passive Semi-passive Active
  • 5. TYPES OF RFID TAGS Active Tags Semi-passive Tags Passive Tags• Use a battery • Contain built-in • Derive their power from• communicate over batteries to power the the field generated by distances of several chip’s circuitry, resist the reader meters interference and • without having an circumvent a lack of active transmitter to power from the reader transfer the information signal due to long stored distance. • They are different from active tags in that they only transmit data at the time a response is received
  • 6. APPLICATIONSFrequency Appx. Read Data Speed Cost of Tags Application RangeLow Frequency (125kHz) <5cm Low High • Animal Identification (passive) • Access ControlHigh Frequency (13.56 10 cm – 1m Low to Moderate Medium to Low • Smart CardsMhz) (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)

  • 14. CONCLUSIONPositive 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 usNegative Cost is relatively remain high (compare to barcode) RFID signals may have problems with some materials RFID standards are still being developed
