Aadhaar is a 12-digit unique identification number issued by the Unique Identification Authority of India (UIDAI) to each individual of the country. It is one of the most important documents to be submitted to avail of various government schemes & benefits. Apart from that, an Aadhaar card is quoted to complete the KYC process and other related services. It also acts as a proof of identity and thus, it is mandatory for every individual to have one.
The main objective of an Aadhaar card is to promote and offer reliable, translucent and exemplary government services to Indian citizens. An Aadhaar card is made out of the user’s demographic information and biometric data. It is allotted to the individual only after all the data is verified and is found unique to every other citizens’ data.
There is so much more to be discussed about an Aadhaar card; some of which is explained below.
What are the features of an Aadhaar card?
Listed below are the features of an Aadhaar card and what makes it unique among other legal documents like PAN card-
All the allotted Aadhaar numbers are unique to each other as they are generated by using the applicant’s demographic information and biometric data like iris scan, fingerprints and a photograph. In any case, the biometric data of an applicant can never match the biometric data of another individual; thus, an Aadhaar card eliminates the scope of duplication.
The de-duplication process to generate an Aadhaar number compares the applicant’s demographic information and biometric data with the available records in the UIDAI database. The process results in verifying whether the applicant’s details are already recorded in the database or not. The Aadhaar number is only generated once the applicant’s information is found unique to other applicants. It is to be noted that an applicant can enrol for an Aadhaar only once; however, if he/she tries to enrol more than once, the subsequent enrolments get rejected.
|What makes Aadhaar Unique- It is generated only after verifying the applicant’s demographic information and biometrics details with the records available in the UIDAI database.|
An Aadhaar card can be accepted online anywhere across the nation for authentication purposes. This feature of an Aadhaar card makes it feasible for users to migrate from one state to another without the worry of changing addresses or its details every now and then.
|What makes Aadhaar Portable- Aadhaar card is a legal document and can be accepted anywhere across the nation online|
Aadhaar number is generated without capturing details like religion, income, caste, health, the geography of an applicant. It is a number that is randomly generated and is devoid of any intelligence. An applicant is only required to provide his/her demographic information and biometric data during the enrollment process to get an Aadhaar number.
|How Aadhaar number is a Unique Number- Aadhaar number is devoid of any intelligence and it does not consider details like applicant’s religion, caste, health status, geography, etc.|
Scalable Technology Architecture
The UID architecture is made scalable and open. All the demographic information and biometric data of an applicant is stored centrally and can be authenticated from anywhere across the nation. The Aadhaar authentication service is built to manage and handle at least 100 million authentications in a day.
|How does the UID Structure look like- The UID architecture is made to handle around 100 million authentications in a day while managing millions of applicant’s data|
Open Source Technologies
UIDAI open-source architecture is made in a manner that precludes dependence on a specific storage system, specific operating systems, specific computer hardware, specific database vendor or any specific vendor technologies to scale. The application is built using open source or open technologies and is structured to address scalability in a vendor-neutral manner. It also allows the co-existence of heterogeneous hardware within the same application.
