3.  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 object

4.  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

• They are different
from active tags in
that they only

received

10.  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
