Conclusionof RFIDand opportunities 3. 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 When
these tags pass through a field generated by a compatible reader,
theytransmit this information back to the reader, thereby
identifying the object 4. 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 5. RFID TAG The RFID tag
consists of an integrated circuit (IC) embedded in athin film
medium. Information stored in the memory of the RFID chip is
transmitted bythe antenna circuit embedded in the RFID inlay via
radio frequencies, toan RFID reader 3 types Passive Semi-passive
Active 6. TYPES OF RFID TAGS Active Tags Semi-passive TagsPassive
Tags Use a battery Contain built-in Derive their power communicate
over batteries to power the from the fielddistances of several
chips circuitry, resist generated by the readermeters interference
and without having an circumvent a lack of active transmitter to
power from the readertransfer the signal due to long information
stored distance. They are different from active tags in that they
only transmit data at the time a response is received 7.
