About things of internet and types of it

1. PRESENTATION
ON
RFID
BY:-ANKIT (MCA 2ND SEM)
UNIV. ROLL NO.:221280410012

2. INTRODUCTION
• RFID STANDS FOR RADIO FREQUENCY IDENTIFICATION.
• IT IS WIRELESS COMMUNICATION TECHNOLOGY WORKING ON RADIO FREQUENCY OR
RADIO WAVES
• THIS TECHNOLOGY IS AUTOMATICALLY IDENTIFIES THE OBJECTS OR TRACKING THE
OBJECTS
• THIS OBJECT CAN BE ANYTHING LIKE BOOK IN LIBRARY , OR VEHICLES ETC
• NOT ONLY THE OBJECT , BUT IT CAN ALSO BE USED TO TRACK THE ANIMALS AS
WELL AS BIRDS
• RFID TECHNOLOGY EXCHANGE DATA BETWEEN A READER AND A ELECTRIC TAGS
ATTACHED TO A OBJECT FOR THE PURPOSE OF IDENTIFICATION AND TRACKING

3. COMPONENTS OF RFID

4. RFID TAGS
• AN RFID TAG COMPRISES A MICROCHIP CONTAINING IDENTIFY INFORMATION
AND AN ANTENNA THAT TRANSMITS THIS DATA WIRELESSLY TO THE READER.
• TYPES OF TAGS
1. PASSIVE TAGS:-IT IS COMMON TAG WHICH ARE SMALL AND USE
ELECTROMAGNETIC ENERGY IN RADIO FREQUENCY WAVES SO THESE TAGS
DONOT REQUIRE BATTERY POWER.
2. ACTIVE TAGS :-THESE ARE EQUIPPED WITH BATTERY AND THUS A LIMITED LIFE
DUE TO BATTERY
SEMI ACTIVE TAGS :- THEY USE BUILT IN BATTERY TO POWER THE CIRCUIT ONLY
WHEN READER FIRST ENERGIZING THE TAG OR SIGNAL.

5. RFID READER
• AN RFID READER IS AN ACTIVE DEVICE THAT IS USED TO READ
INFORMATION STORED IN TAGS OR TRANSMIT INFORMATION TO THE
MICROCONTROLLER.
• IT CONSISTS OF AN ANTENNA EITHER INTERNAL OR EXTERNAL WHICH
CONTINUOUSLY EMITS RADIO WAVES SO THAT RFID TAGS CAN
RESPOND IT TO BY SENDING BACK THERE INFORMATION.
• THIS INFORMATION IS GENERALLY KNOWN AS ELECTRONIC PRODUCT
CODE (EPC)

6. MICRO CONTROLLER
• THIS IS THE CPU OF OUR PROJECT SECURITY SYSTEM. THE VARIOUS FUNCTION
OF THIS DEVICE ARE LIKE READING DIGITAL FROM READER TURN ON BUZZER
FOR INVALID CARD, TURN ON THE MOTOR OR REPLY IF CARD IS VALID

7. LCD
• LCD STANDS FOR LIQUID CRYSTAL DISPLAY
• LIQUID CRYSTAL DISPLAY IS USED TO DISPLAY ALPHABET ALONG WITH NUMBERS
ON IT SCREEN.
• LCD DISPLAY IS USED TO DISPLAY THE DETAILS OF THE CARD.

8. APPLICATION
PRODUCT TRACKING – RFID TAGS ARE INCREASINGLY USED AS A COST-EFFECTIVE
WAY TO TRACK INVENTORY AND AS A SUBSTITUTE FOR BARCODES.
TOLL ROAD PAYMENTS – HIGHWAY TOLL PAYMENT SYSTEMS, SUCH AS E-Z PASS IN
THE EASTERN STATES, USES RFID TECHNOLOGY TO ELECTRONICALLY COLLECT TOLLS
FROM PASSING CARS.
PASSPORTS – A NUMBER OF COUNTRIES, INCLUDING JAPAN, THE UNITED STATES,
NORWAY, AND SPAIN INCORPORATE RFID TAGS INTO PASSPORTS TO STORE
INFORMATION (SUCH AS A PHOTOGRAPH) ABOUT THE PASSPORT HOLDER AND TO
TRACK VISITORS ENTERING AND EXITING THE COUNTRY.

9. • IDENTIFICATION – RFID CHIPS CAN BE IMPLANTED INTO ANIMALS AND PEOPLE
TO TRACK THEIR MOVEMENTS, PROVIDE ACCESS TO SECURE LOCATIONS, OR
HELP FIND LOST PETS.
• SHIPPING – LARGE SHIPMENTS OF MATERIALS, SUCH AS RETAIL GOODS, OFTEN
UTILIZE RFID TAGS TO IDENTIFY LOCATION, CONTENTS, AND MOVEMENT OF
GOODS. WAL-MART IS ONE OF THE LARGEST CONSUMERS OF THIS TECHNOLOGY TO
ASSIST IN TRACKING SHIPMENTS OF MERCHANDISE.
• LIBRARIES – LIBRARIES USE RFID TAGS IN BOOKS AND OTHER MATERIALS TO
TRACK CIRCULATION AND INVENTORY, STORE PRODUCT INFORMATION (SUCH AS
TITLES AND AUTHORS), AND TO PROVIDE SECURITY FROM THEFT. BECAUSE RFID
TAGS CAN BE SCANNED WITHOUT PHYSICALLY TOUCHING THE ITEM.

10. ADVANTAGES OF RFID
• RFID TAGS ARE VERY SIMPLE TO INSTALL/ INJECT INSIDE THE BODY OF ANIMAL,
THUS HELPING TO KEEP A TRACK ON THEM
• RFID APPLICATION CAN AUTOMATICALLY TRACK THE MOMENT OR GOODS AND
UPLOAD THE INFORMATION TO THE ERP THROUGH THIS SAVING TIME AND MONEY
• IMPROVING DATA ACCURACY AND AVAILABILITY BECAUSE DATA IS BEING CONTROL
AND UPLOADED ELECTRONICALLY RFID ALSO AVOIDS TRANSCRIPTION ERROR,
DUPLICATION OF DATA AND MISSING TERM.
• RFID TECHNOLOGY IS USED IN TOOL BOOTHS TO IMPLEMENT FAST TAG WHERE THE
VEHICLE IS IDENTIFIED BY THE STICKER PUT ON THE VEHICLE

11. CONCLUSION
POSITIVE:-
• RFID IS HAVE CONTACTLESS READING TECHNOLOGY AND CAN READ THROUGH
OTHER MATERIALS.
• OLD MORE DATA THEN BARCODE DOES.
• RFID TAGS DATA CAN BE CHANGED OR ADDED.
• MORE EFFECTIVE , BRING A LOT OF CONVENIENCE TO US.
NEGATIVE:-
• COST IS RELATIVELY REMAIN HIGH (COMPARE TO BAR CODE).
• RFID SIGNALS MAY HAVE PROBLEMS WITH OTHER MATERIALS.
• RFID STANDARDS ARE STILL BEING DEVELOPED.
