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
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
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
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

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
