RFID RFID = Radio Frequency Identification Electronic labeling and wireless identificationof 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 fieldgenerated by a compatible reader, theytransmit this information back to the reader,thereby identifying the object 4. RFID components A basic RFID system consists of thesecomponents: A programmable RFID tag/inlay for storing itemdata; Consisting of an RFID chip for data storage an antenna to facilitate communication withthe RFID chip A reader/antenna system to interrogate theRFID inlay Application software and a host computersystem 5. RFID Tag The RFID tag consists of an integrated circuit(IC) embedded in a thin film medium. Information stored in the memory of the RFIDchip is transmitted by the antenna circuitembedded in the RFID inlay via radiofrequencies, to an RFID reader 3 types Passive Semi-passive Active 6. Types of RFID TagsActive TagsUse a batterycommunicate overdistances of severalmetersSemi-passive TagsContain built-inbatteries to power thechips circuitry, resistinterference andcircumvent a lack ofpower from thereader signal due tolong distance.They are differentfrom active tags inthat they only transmitdata at the time aresponse is receivedPassive TagsDerive their powerfrom the fieldgenerated by thereaderwithout having anactive transmitter totransfer theinformation stored 7.
