Aadhaar Project

India has a population of 1.2 billion people and approximately 400 million people are unable to prove their identity (in 2011)... The inability to prove one’s identity precludes the poor, the marginalized, and the underprivileged populations of India from gaining access to benefits and subsidies, applying for welfare benefits, accessing education, opening a bank account, or attaining employment.

The goal of Indian government officials in implementing a broad identification system is to successfully address the concerns of national security, corruption, and anti-poverty efforts. There have been many documented cases of fake identities, fraud, and duplication of welfare services across the country… In order to improve the economic situation of all of its residents, the Unique Identification Authority of India (UIDAI) implemented an ambitious and innovative program known as Aadhaar.

Key Activities


Enrollment is free and occurs through duly designated third-party enrollment agencies. To become an official enrollment agency, an organization is required to go through proper training and testing on procedures and use of the enrollment kit. Each kit is packed into a briefcase and includes the following: a laptop, the enrollment software, fingerprint reader, iris scanner, webcam, laser printer, and monitor. Participation in Aadhaar is voluntary for all residents. Crucially, it enables eKYC – a function which greatly enhances the efficiency of the KYC process and fosters financial inclusion. To enroll, residents can go to any authorized enrollment agency, complete an Aadhaar application form, and present current identification documents. If an enrollee does not have identification documents, they can still enroll with the help of an “introducer” – a person whose identity has already been verified. The “introducer” vouches for the enrollee, sidestepping the requirements for identification documents. The enrollee will then have their biometric data recorded and is entered into the database. The assigned Aadhaar number for an individual is connected to all biometric data collected during the enrollment process. A trained enrollment center employee photographs the enrollee, records the iris scans of the eyes, collects demographic information, and takes imprints of all 10 fingers. Each enrollee’s data is then uploaded to the Central Identification Data Repository (CIDR) for deduplication. The term “deduplication” refers to the process where the CIDR checks to determine whether or not the biometric data submitted already exists in the database. If no equivalent record exists, then a unique, randomly generated 12-digit number will be mailed to the enrollee.

One of the reasons why India’s program has been able to operate on such a large scale is the formation of public-private partnerships throughout the country.
