RFID systems consist of RFID tags containing chips that transmit data to readers via radio frequencies. Passive tags derive power from readers while active tags have batteries. Common applications include access control, asset tracking, and electronic toll collection. A survey found RFID benefits industries through improved efficiency, inventory turnover, and reduced costs and manpower. Further development opportunities exist in medical and library uses of RFID.

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
RFID

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
RFID components

5. 
 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
 3 types
 Passive
 Semi-passive
 Active
RFID Tag

6. 
Active Tags
•Use a battery
•communicate over
distances of several
meters
Semi-passive Tags
•Contain built-in
batteries to power the
chip’s circuitry, resist
interference and
circumvent a lack of
power from the reader
signal due to long
distance.
•They are different from
active tags in that they
only transmit data at
the time a response is
received
Passive Tags
•Derive their power
from the field generated
by the reader
•without having an
active transmitter to
transfer the information
stored

15.  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
