Transcript

  • 1. 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
  • 2. 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
  • 3. 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
  • 4. 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

  • 10. SURVEY RESULT Types of industries that respondents think it is possible to apply RFID technology Document Management 8% Inventory Control 10% Security Customer Services 8% 5% Library Management Hotel Management 21% Other 5% 18% Banking and Finance 5% Pharmaceutic manufacturing Social Services industries Logistics and Supply Chain 3% 15% Management 20%

  • 13. 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
