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

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
