RFIDRFID

RFID = Radio Frequency IdentificationElectronic 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 object

RFID componentsRFID 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

RFID TagRFID Tag

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

ConclusionConclusion

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 developed
