This document discusses RFID technology and its applications. It begins with an introduction to RFID, describing the components and types of RFID tags. It then outlines several common applications of RFID technology, including credit cards, transportation payment systems, access control, and supply chain management. The document also presents the results of an online survey that found logistics and supply chain management to be the most common industry seen as suitable for RFID application. It concludes with a discussion of further potential developments in medical and library uses of RFID and both positives and limitations of the technology.

3. 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

4. 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

5. 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

6. 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

15. 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
