  1. 1. RFID APPLICATIONLi Fung Tsing1221384510/18/2012
  2. 2. Introduction Future Applications development of SIRI Survey Conclusion and results opportunities
  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. Type 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 circuitry, generated by the several meters resist interference reader and circumvent a • without having an lack of power from active transmitter the reader signal to transfer the due to long information stored distance. • They are different from active tags in that they only transmit data at the time a response is received
  7. 7. Frequency of RFID tags in differentapplicationsFrequency Appx. Read Range Data Speed Cost of Application TagsLow 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)
