Significance of Biometric Data of an Individual

  • The Aadhaar program, launched in India in 2009, sought to issue a unique identification number for each individual in the country. This unique number is the 12-digit Aadhaar number, which can be biometrically verified.

  • The biometric data that an individual gives at the time of Aadhaar biometric update or enrollment is very crucial. The Aadhaar number is not issued right away, after collecting biometric details. The data collected is cross-verified and compared with the existing details in the database.

  • This is done to ensure that there is no matching set of data already recorded. Only when it has been verified that the biometric details submitted are unique is the Aadhaar issued or updated. This ensures that there is no duplication in the Aadhaar numbers, since fingerprints and iris scans are unique for each individual.

Aadhaar Biometric Data

Whether it is the initial recording of biometric data or any subsequent Aadhaar biometric update, three sets of biometric data are recorded, as follows.

  • The cardholder’s photograph

  • The fingerprints of all 10 fingers

  • An iris scan of both eyes


At the time of biometric update in Aadhaar, these details must be provided by the individual.

How to Submit Aadhaar Biometric Data?

It is important to understand how to submit your biometric data when you go in for an Aadhaar biometric update. Here is a closer look at what you need to do.

  • Provide your demographic details.

  • Have your photograph taken.

  • Provide the fingerprints of all 10 fingers.

  • Have the irises of both eyes scanned.

Aadhaar Biometric for Children

  • The Aadhaar card is not issued only for individuals above the age of 18. Even children and newborns have this identity card.

  • Children below the age of 5 are issued a Baal Aadhaar, which does not include their biometric details. Instead, the parent’s details are recorded. It is only when a child attains the age of 5 that their biometric data is recorded.

  • Thereafter, when the child attains 15 years of age, the Aadhaar biometric update has to be performed once again. The procedure to be followed for the update is the same for adults and children.

Fees and Charges for Aadhaar Biometric Update

  • If you wish to perform an Aadhaar card biometric update, you need to pay the fees and charges applicable for the procedure.

  • In case of biometric updates for adults, the fee is Rs. 50, inclusive of GST. This is applicable each time you wish to update your biometric details.

  • For children, the Aadhaar biometric update that is done at the age of 5, for the first time, is free of charge. Similarly, the first Aadhaar card biometric update done after the child attains 15 years of age is also free.

  • However, any subsequent biometric updates for the child will cost Rs. 50.


As the Aadhaar card is a vital document used for identity and residence proof, it must contain the right details. This card is made using your personal and biometric details. In the case of children, biometrics like fingerprints usually get changed with age. Thus, it’s important to update these details. You can update these details by visiting your nearest Aadhaar card centre. You may refer to the above-mentioned details to know more.
