2. + 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

3. + 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

4. + 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

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

6. Frequency Appx. Read Range Data Speed Cost of Tags Application

12. + In medical uses and library management

14. + 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
