  1. 1. CONTENTS 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
  2. 2. 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
  3. 3. 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
  4. 4. TYPES OF RFID TAGS Active Tags • Use a battery • communicate over distances of several meters Semi-passive Tags • Contain built-in batteries to power the chip’s circuitry, resist interference and circumvent a lack of power from the reader signal due to long distance. • They are different from active tags in that they only transmit data at the time a response is received Passive Tags • Derive their power from the field generated by the reader • without having an active transmitter to transfer the information stored
  5. 5. APPLICATIONS Frequency Low Frequency (125kHz) Appx. Read Range <5cm High Frequency (13.56 Mhz) (passive) 10 cm – 1m Low to Moderate Medium to Low • • (passive) 3m -7m Moderate to High Low • • Payment (paywave) Logistics and Supply Chain (passive) 10m -15m High High • • Baggage Tracking Electronic toll collection (Autotoll) • Container Tracking Ultra High Frequency (433, 868-928 Mhz) Microwave (2.45 & 5.8 Ghz) (passive) 20m – 40m (active) Data Speed Cost of Tags Application Low High • Animal Identification Access Control Smart Cards

  12. 12. 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
