  • RFID APPLICATIONGao Tianshu 12250341 17 April 2013
  • CONTENT FutureIntroduction development applications Survey result conclusion of RFID and opportunities
  • 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
  • RFID COMPONENTS• A basic RFID system consists of these components: • A programmable RFID tag/inlay for storing item data;• A reader/antenna system to interrogate the RFID inlay• Application software and a host computer system
  • 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
  • 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 active circumvent a lack of transmitter to transfer the power from the information stored 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
  • APPLICATIONS• Credit Cards with RFID (Paywave function)
  • CURRENT APPLICATIONS
  • ONLINE SURVEY• Target: SME• Information: Opinion on RFID and its applications• Site: http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPRZuy uWtsk4
  • SURVEY RESULT Benefits of using RFID in different industries Manufacturing Retailing Transportation Warehousing 4 4 4 4 3 3 2 2 2 1 1 1 1 1 0 0 0 0 Enhanced customer satisfaction Improved efficiency 0 0 Increased inventory turnover rate Reduced manpower Reduced total cost
  • FURTHER DEVELOPMENT• In medical uses and library management
  • VIDEO
  • CONCLUSION • 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
