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 TAGSActive Tags

Use a battery

communicate over distances of several

meters

Semi-passive

TagsContain 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
