INTRODUCTION:-

WHAT IS A RFID CARD?

Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to object

It is an extension to bar code

INVENTION:-

The first patent to be associated with the abbreviation RFID was granted to Charles Walton in 1983

TYPES:-Contact RFID cards

Contact RFID cards have a contact area of approximately 1 square centimetre (0.16 sq in), comprising several gold-plated contact pads. These pads provide electrical connectivity when inserted into a reader

Contactless RFID cards

A second card type is the contactless RFID card, in which the card communicates with and is powered by the reader through RF induction technology (at data rates of 106–848 kbit/s). These cards require only proximity to an antenna to communicate

POWER SUPPLY:-

It basically consists of a Transformer to step down the 230V ac to 18V ac followed by diodes. Here diodes are used to rectify the ac to dc. After rectification the obtained rippled dc is filtered using a capacitor Filter. A positive voltage regulator is used to regulate the obtained dc voltage

COMPONENT DESCRIPTIONLiquid crystal displays

(LCD s) have materials which combine the properties of both liquids and crystals.

buzzer A buzzer or beeper is a signalling device, usually electronic, typically used in automobiles, household appliances such as a microwave oven, or game shows

DC MOTOR:A DC motor is designed to run on DC electric power. It is used to control the closing/opening of the door using L293D IC. The motor works as per the voltages given by the L293D IC, either in clockwise direction or in anti-clockwise direction RFID READERs:

Contact smart card readers are used as a communications medium between the smart card and a host, e.g. a computer, a point of sale terminal, or a mobile telephone

L293D:

L293D is a typical Motor driver or Motor Driver IC which allows DC motor to drive on either direction

WORKING PRINCIPLE:-• The RFID module is interfaced with the micro controller and when the

card is inserted into the reader, it reads the data in the card. If the data in the card is matched with the data stored in the program memory, then it displays authorized message, if the data is not matched it displays unauthorized as per the code logic.

• For authorized message, the door will be opened and closes automatically after a small delay. If it is an unauthorized person it alerts the persons through a buzzer. The smart card reader alerts the buzzer whenever it reads the data from the smart card. The door will be driven by DC gear motor by l293d driver

Software used

•Embedded c

•Keil software

SECURITY ACCESS:-Rfid cards have been advertised as suitable for personal identification

tasks, because they are engineered to be tamper resistant. The chip usually implements some cryptographic algorithm. There are, however, several methods for recovering some of the algorithm's internal state.

Differential power analysis involves measuring the precise time and electrical current required for certain encryption or decryption operations. This can deduce the on-chip private key used by public key algorithms such as RSA. Some implementations of symmetric ciphers can be vulnerable to timing or power attacks as well.

rfid cards can be physically disassembled by using acid, abrasives, or some other technique to obtain unrestricted access to the on-board microprocessor. Although such techniques obviously involve a fairly high risk of permanent damage to the chip, they permit much more detailed information (e.g. photomicrographs of encryption hardware) to be extracted.

BENEFITS:-

Enhances safety and security.

Portability.

Reliability..

Reconfigurable and reusable.

FUTURE SCOPE:- Health ServicesThe card can be used to store information such as administrative, medical, biological, and pharmaceutical records. The card simplifies the administrative process and enables doctors to have access to a more complete and comprehensive healthcare information. EducationThe card has the function of identifying the student and also acts as an electronic purse and can be used purchase products from stores or tickets to public transportation. TransportationRechargeable contact-less cards allow ticket-less and cash-less travels. Parking and telecommunications can also be paid using the smart card. This will simplify the passenger boarding process. WelfareCard can be used to identify the holder using a series of personal keys and fingerprint. The card holder then uses the card to access government databases and receive the welfare payment. The security will help eliminate fraud.

CONCLUSION:-

 RFID cards can add convenience and safety to any transaction of value and data. Evaluations of performance, cost and security that will produce a smart card system that fits today's needs in future, which leads to better business for everybody
