2. RFID (RADIO FREQUENCY IDENTIFICATION) IS A TECHNOLOGY THAT
INCORPORATES THE USE OF ELECTROMAGNETIC OR ELECTROSTATIC COUPLING
IN THE RADIO FREQUENCY (RF) PORTION OF THE ELECTROMAGNETIC SPECTRUM
TO UNIQUELY IDENTIFYAN OBJECT, ANIMAL, OR PERSON.
3. IN 1945, LÉON THEREMIN INVENTED AN ESPIONAGE TOOL FOR THE SOVIET
UNION WHICH RETRANSMITTED INCIDENT RADIO WAVES WITH THE AUDIO
INFORMATION. SOUND WAVES VIBRATED A DIAPHRAGM WHICH SLIGHTLY
ALTERED THE SHAPE OF THE RESONATOR, WHICH MODULATED THE REFLECTED
RADIO FREQUENCY. EVEN THOUGH THIS DEVICE WAS A COVERT LISTENING
DEVICE, NOT AN IDENTIFICATION TAG, IT IS CONSIDERED TO BE A PREDECESSOR
OF RFID, BECAUSE IT WAS LIKEWISE PASSIVE, BEING ENERGIZED AND ACTIVATED
BY WAVES FROM AN OUTSIDE SOURCE
4. THE RFID SYSTEM CONSISTS OF A TAG AND THE TAG IS MADE UP OF A MICROCHIP
WITH AN ANTENNAAND ALSO A READER WITH AN ANTENNA.
INITIALLY THE READER TRANSMIT THE ELECTROMAGNETIC WAVES.
THE TAG ANTENNA RECEIVES THESE WAVES AS IT IS RECEIVED TO TURN THE
WAVES.
THE PASSIVE TAG OF RFID SUPPLIES POWER TO THE CIRCUIT OF THE MICROCHIP
AS IT HAS THE FEATURE OF EXTRACTING THE POWER.
THE CHIP MODULATES THE AND AFTER THIS READER TRANSFORMS THE WAVES
INTO DIGITAL INFORMATION.
5. IN THE CONSUMER AVAILABILITY.
IN THE AUTOMATIC CHECKOUT.
IN THE SECURITY.
IN THE THEFT PROTECTION.
IT ASSET TRACKING.
6. WHETHER FORECASTS.
SENSES OF ROAD CONDITION WITH USE OF BEACONS.
NOISE LEVEL MONITORING.
PERSONAL IDENTIFICATION.
I-PASS.
7. FOR A READING OF THE TAG, THE POSITION OF THE TAG DOES NOT NEED TO BE IN
THE LINE OF SIGHT IN ACCORDANCE WITH THE RECEIVE.
THESE TAG CAN SAVE HUGE DATAAND EVEN OBEY THE INSTRUCTIONS.
IT HAS THE FEATURE OF PIN POINTING THE LOCATION.
TAGS CAN BE READ ONLY AS WELL AS READ/WRITE UNLIKE BARCODES.
IT PROVIDES LOCATION TO THE READER ALONG WITH ITS ID.
RFID TAGS ARE USED FOR TRACKING LUGGAGE AS WELLAS FOR MONITORING
HEALTH HISTORY OF PATIENTS IN THE HOSPITALS.
8. THE PROGRAMMING OF THE RFID DEVICES TAKE MORE TIME.
THE ISSUES RELATED WITH RFID ARE THE TECHNICAL,PROBLEMS,SECURITY
PROBLEMS AND PRIVACY.
ACTIVE RFID IS COSTLY DUE TO USE OF BATTERIES.
RFID DEVICES NEED TO BE PROGRAMMED WHICH REQUIRES ENOUGH AMOUNT
OF TIME.
THE COVERAGE RANGE OF RFID IS LIMITED WHICH IS ABOUT 3 METERS.
THE EXTERNAL ELECTROMAGNETIC INTERFERENCE CAN LIMIT THE RFID
REMOTE READING.
9. THIS PAPER PRESENTED A SURVEY ON RFID TECHNOLOGY. RFID TECHNOLOGY
HAS A BIG POTENTIAL TO BECOME UBIQUITOUS IN THE NEAR FUTURE. TODAY IT
IS ALREADY SUCCESSFULLY USED IN SUPPLY CHAIN MANAGEMENT TO TRACK
PALLETS OF ITEMS. TRACKING ALLOWS BETTER COORDINATION AND CONTROL
IN THE PRODUCTION CYCLE. NOW THE INDUSTRY IS PUSHING TOWARDS ITEM-
LEVEL TAGGING TO INCREASE THE CONTROL EVEN FURTHER. HOWEVER, THAT
ALSO CREATES CONCERNS, MOST COMMON PRIVACY CONCERN, BUT ALSO
OTHER SECURITY RELATED ISSUES. THE PAPER PRESENTED POSSIBLE SCENARIOS
HOW PRIVACY CAN BE COMPROMISED BY RFID TAGS BUT ALSO SEVERAL
SOLUTIONS TO PROTECT AGAINST IT. SINCE RFID TECHNOLOGY BECOMES MORE
AND MORE COMMON, ATTACKS AGAINST THE SYSTEM ITSELF START TO APPEAR.
THIS PAPER LISTED THE MOST COMMON, STARTING FROM COMMON SNIFFING
AND EAVESDROPPING OVER DENIAL OF SERVICE TO NEW RFID VIRUSES
