1.Introduction
5.Conclusion
RFID
• 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 components
• 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 Tag
• 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
Types of RFID Tags
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

Conclusion
• 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
