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 enrollment, with the records in the UIDAI database to verify if the resident is already in the database or not. An individual needs to enroll for Aadhaar only once and after de-duplication, only one Aadhaar shall be generated. In case, the resident enrolls more than once, the subsequent enrollments will be rejected.
Aadhaar can authenticate anywhere online gives nationwide portability. This is a very important feature because Every month Many Indians Migrated from one state to Another from Rural to Urban Civilization. So, Portability will help them to use Aadhar all over the Nation.
Aadhar Number generates Randomly
Aadhaar number will be generated Randomly and Every Aadhar number is UNIQUE. A person willing to enroll has to provide minimal demographic along with bio metric information like Finger Prints, ID Proof etc during the enrollment process.
All In One ID Proof

Scalable Technology Architecture
The UID architecture is open and scalable. Resident’s data is stored centrally (at UIDAI) and authentication can be done online from anywhere in the country. Aadhaar Authentication service is built to handle 100 million authentications a day (This Indicates that UIDAI has Huge Capacity).
Aadhar has Open Source Technology
Open source architecture precludes dependence on specific computer hardware, specific storage, specific OS, specific database vendor, or any specific vendor technologies to scale. Such applications are built using open source or open technologies and structured to address scalability in a vendor neutral manner and allow coexistence of heterogeneous hardware within the same application.
