  • 1. Lee Ching Yin 13210289 Tuesday, October 15, 2013
  • 2. • 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
  • 3. • 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
  • 4. • 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
  • 5. Credit Cards with RFID (Paywave function) Octopus (Smart Card)
  • 6. Autotoll (Electronic toll collection) Access Control
  • 7. • Target: SME • Information: Opinion on RFID and its applications • Site: • http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuyuWtsk4

  • 10. • In medical uses and library management
  • 11. • 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
