This document discusses radio frequency identification (RFID) technology. It describes the basic components of an RFID system including RFID tags, readers, and application software. It outlines the three main types of RFID tags and discusses their typical read ranges and applications. The document also provides examples of current RFID applications in various industries and presents results of a survey on possible areas for future RFID use. It concludes that RFID provides benefits over barcodes but also faces challenges related to costs and standardization.


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

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
