The Aadhaar card is meant to provide identity to its holder. It does not guarantee any entitlements or benefits. Basically, it is linked to a person's bio metric or demographic information.
The Aadhaar card is a scheme designed to benefit the poor people of India. It is meant to improve service delivery to the poor. Basically most of the poor in India do not have proper identification papers. This means that the Aadhaar card will be their first form of authentication that these people will have access to.
It will also help to solve the problem of illegal immigration to India.
India has databases that are full of fraud information or duplicate entries. This is done in order to provide benefits to certain people. The Government wants that this wrong information should not be used for making the database for this card. Hence, the Government has to make a fresh database in order to gather this information. Hence, the Aadhaar card will help to solve the problem of corruption in India. There are many problems being faced while compiling this database.
The main problem is that most of the poor people in India do not have any kind of papers that would be able to verify their demographic as well as biometric information.
In addition, India has a large mass of uneducated population. They are not able to understand the importance of Aadhaar card and tend to withhold information.
Many people can spell their name in their regional language only. India being such a diverse country, the Aadhaar software will not be able to record all the names in their local language. And names tend to take a totally different spelling and meaning when recorded in another language that is not native. Besides, people are doubtful of this card being able to reach those who are in remote areas.
