4. RFID
10/15/2015RFID & Its Application 4
• 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
5. 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

6. 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

7. TYPES OF RFID TAGS
10/15/2015RFID & Its Application 7
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

16. 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
