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
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
•Derive their power from
the field generated by
the reader
•without having an
active transmitter to
transfer the information
stored

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
