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
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
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
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
APPLICATIONS Frequency of RFID tags in different applications Frequency Appx. Read Data Speed Cost of Tags Application Range Low Frequency <5cm Low High • Animal Identification (125kHz) (passive) • Access Control High Frequency 10 cm – 1m Low to Medium to Low • Smart Cards (13.56 Mhz) Moderate (passive) • Payment (paywave) Ultra High 3m -7m Moderate to Low • Logistics and Supply Frequency (433, High Chain 868-928 Mhz) (passive) • Baggage Tracking Microwave (2.45 10m -15m High High • Electronic toll collection & 5.8 Ghz) (Autotoll) (passive) • Container Tracking 20m – 40m (active)
