Aadhaar Plus Project is mainly based on the RFID technology. In this project we used Radio Frequency Identification technology (RFID); we have an RFID card which is issued to each and every citizen with a unique identification number in it. This card will be used as a unique identification and will be used in various aspects which have been described in the following Report. Now before going to the details of the Project we should first know about the RFID technology. Radio frequency identification (RFID) technology has been widely adopted in access control system.

The control modules are developed based on embedded systems. Embedded systems are becoming increasingly common due to the fast deployment of advanced microcontrollers offering high processing speeds at an affordable price and allowing for simple and reliable use of Open Source software. The presented system uses a microcontroller with a standard Ethernet interface, to validate users presenting an RFID Card.

The user credentials are validated locally or in a central database. Authorized users are given access to reserved areas. By using a powerful database, very flexible and complex high level administration and management functions can be implemented. As we all know about the Indian government’s AADHAAR a unique identification Project which is being prepared by INFOSYS TECHNOLOGIES. This Project is a higher or we can say a modified version of the AADHAAR card. This card will be unique for every citizen in India. Its basically a Radio Frequency Identicifaction card, through which the particular details of a person will be accessed.


The four modules of this RFID card are as follows

• Passport

• Hospital Details

• Smart Parking

• Driving Licence


The module will have all the necessary details of the passport, like all the issued VISA, Address, Name, Identification, and Photograph. The module consists of VISA history, date of issue and expiry details. AADHAR PLUS card will act as Passport, and we will not have to take the passport separately. The headache of carrying a passport booklet will be solved and just this card can be used in various purposes. In National Information Centre (NIC) the database size will be reduced so it will be easier to maintain, update and make changes.

There will be only one database for passport and other modules. So it will reduce the size of database and resource can be used properly and more structured manner. The traditional passport is issued to citizens of India for the purpose of international travel. They act as proof of Indian nationality. The Consular Passport & Visa (CPV) Division of the Ministry of External Affairs, functioning as the central passport organisation, is responsible for issuance of Indian passports to all eligible Indian citizens.

Passports are issued from 37 locations across the country and 162 Indian missions abroad Types of traditional passports are

Regular passport (Deep Blue/Black cover) - Issued for ordinary travel, such as vacations and business trips (36 or 60 pages)

Diplomatic passport (Maroon cover) - Issued to Indian diplomats, top ranking government officials and diplomatic couriers.

Official passport (White cover) - Issued to individuals representing the Indian government on official business

In addition, select passport offices in India as well as overseas missions are authorised to issue Regular Indo-Bangladesh passports and Indo-Sri Lankan passports, to Indian nationals resident in West Bengal, the North Eastern States, Tamil Nadu and Pondicherry. These two passports permit travel to Bangladesh and Sri Lanka only and are not valid for travel to other foreign countries

In our project we don’t have any such types. We have only one card which will work for all type of passports. This project not only deals with passport but many other domains which are given below. In this particular domain of passport we mainly deal with the issue of VISA and the other important fields of passport. The another important drawback on the traditional passport is that when the pages get over in the passport we have to go for renewal of new one but in this AADHAR PLUS passport system we don’t have to issue a new one as there is no pages involved in this card, there is no chance of getting over with the pages for visa.

There is unlimited storage of visa. It will help overcome another important drawback of traditional passport system. The first RFID passports ("E-passport") were issued by Malaysia in 1998. In addition to information also contained on the visual data page of the passport, Malaysian e-passports record the travel history (time, date, and place) of entries and exits from the country.


It generally includes automating the car-parking payment facility where the RFID card will first check for the available balance in the card (RFID acts as a Smart card) and will deduct the parking charges from the available amount thus reducing the risk of escaping. And it will also reduce the problem of tender exchanges in the parking fee gates and also reduce the problem of carrying cash.

Baltimore/Washington International Thurgood Marshall Airport also strives to make parking less painful. The airport installed a smart parking system for its hourly and daily garages, which combine to offer 13 200 parking spaces. Sensors embedded in each parking space at BWI detect whether the space is occupied, with that information fed into a central parking management system.

As drivers approach BWI on their way to departing flights, they see signs showing the availability of parking at the airport’s garages. As a passenger enters a garage, signs indicate the total number of parking spaces available and the number on each level [6]. At the levels, there are additional signs that tell the passenger how many spaces are available per row.

A light over each space indicates whether it is available: green for open, red for occupied. BWI was the first airport in the country to use smart parking technology, says Jonathan Dean, spokesman for the Maryland Aviation Administration. The technology came to BWI after Maryland’s transportation secretary saw it in use while on a trip to Europe.


It explains that the RFID reader will be connected to the microcontroller with the help of UART and the UART is also connected to the PC/ LAPTOP and the PC or Laptop will execute the software part and show the forms and in that part only we can use the different modules and can entry the data and keep the updates and in this was the project work out.




diagram that shows how processes operate with one another and in what order. It is a construct of a Message Sequence Chart. A sequence diagram shows object interactions arranged in time sequence. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. Sequence diagrams typically are associated with use case realizations in the Logical View of the system under development.

A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner.

An organization's technical staff can find sequence diagrams useful in documenting how a future system should behave. During the design phase, architects and developers can use the diagram to force out the system's object interactions, thus fleshing out overall system design. One of the primary uses of sequence diagrams is in the transition from requirements expressed as use cases to the next and more formal level of refinement.

Use cases are often refined into one or more sequence diagrams. In addition to their use in designing new systems, sequence diagrams can be used to document how objects in an existing (call it "legacy") system currently interact. This documentation is very useful when transitioning a system to another person or organization

The sequence diagram of this card shows how the AADHAR PLUS card works and the steps involved in it. The user is first checked for authorization and if the authorization is correct then only the access will be provided to the user. This authorization is done with the help of a password. This password will be separate for each and every user. In case of Medical Details, this authorization is not required. As in case of an emergency it will not be possible for any user to provide authentication. Thus this module does not need authentication at all.

But the other modules will need authentication as for the security reasons. So that the passport and driving license details are safe and there is no unauthorized or illegal use of those details and in case of smart parking also for keeping our e cash safe we have the password facility so that in case of lost card or theft, there should not be any misuse of the card and so this will help to keep the details safe and secured. The given sequence diagram explains in what sequence and the way the card works, authentication and other processes.



Aadhaar Plus Working Mode

The above shown diagram is a working model. It shows how the RFID SCANNER reads the RFID TAG/CARD and the signal is given to the PC and the modules will be shown. The computer displays four modules which are shown in above diagram and in the right hand side a demo is shown, when we click in the Hospital button it will display another form which will be like the above given demo which will have all the necessary hospital details and all. The same way it will work for each and every module.



Aadhaar Plus Hardware Kit


The figure shows the hardware design of the AADHAR PLUS kit. The designed kit consists of all the hardware requirements for this project. It contains the RFID Reader, Microcontroller 8051 along with the filters. In the right hand side we have step down transformer which converts 120v to12v. It also shows a buzzer which will produce a sound when the card comes near the coil or the scanner. This sound comes out only when the card comes within the range of the reader. Thus the card is read by the RFID reader.


The AADHAR PLUS project has been documented to bring a substantial difference in the Indian Government, by helping them introducing the AADHAR PLUS.

Our current objectives are to

• To make the procedure for applying for passport and driving licence easy and quick.

• In case of emergency/ accident this card will help to get the details about the patient and his medical history.

• This card will also improve the classical parking system by making the parking charges payment automated which will make the process faster and problems related to exchanges will be solved.

• This card will help the traffic police/department to easily check the validity and other related issues of a driving licence.

• Only Administrator can make the changes in the Database.

• It will also act as identity card which will also have the permanent address and other required information in it.
