Features of Aadhaar


This is achieved through the process of demographic and biometric de-duplication. The de-duplication process compares the resident’s demographic and biometric information, collected during the process of enrolment, with the records in the UIDAI database to verify if the resident is already in the database or not. An individual needs to enrol for Aadhaar only once and after de-duplication, only one Aadhaar shall be generated. In case, the resident enrols more than once, the subsequent enrolments will be rejected.


Aadhaar gives nationwide portability as it can be authenticated anywhere online. This is critical as millions of Indians migrate from one state to another or from rural areas to urban centres etc.

Random number

An aadhaar number is a random number devoid of any intelligence. Therefore a person willing to enrol has to provide minimal demographic; along with biometric information during the enrolment process. So the Aadhaar enrolment process does not capture details like caste, religion, income, health, geography, etc.

Scalable technology architecture

The UID architecture is open and scalable. The Resident’s data is stored centrally and authentication; can be done online from anywhere in the country. Although the aadhaar Authentication service is built to handle 100 million authentications a day.


Open source technologies

Open-source architecture precludes dependence on specific computer hardware; specific storage, specific OS, specific database vendor, or any specific vendor technologies to scale. Therefore such applications are built using open source or open technologies and structured to address scalability in a vendor-neutral manner and allow the co-existence of heterogeneous hardware within the same application.
