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 objectRFID
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 systemRFID components
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 ◦ ActiveRFID Tag
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 several the chip’s generated by the meters circuitry, resist reader interference and • without having an circumvent a lack of active transmitter to power from the transfer the reader signal due to information stored long distance. • They are different from active tags in that they only transmit data at the time a response is received Types of RFID Tags

In medical uses and library managementFurther Development
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 developedConclusion
