Aadhaar, a 12-digit unique identification number, is assigned to residents of India. The primary purpose of the Aadhaar card is to establish a robust and universal identification system that can be used across various government and private-sector services. The card includes essential demographic information like the individual's name, photograph, date of birth, gender, and residential address. To enhance security and accuracy, the Aadhaar card incorporates biometric data, comprising fingerprint and iris scans captured during enrolment.

When you have easy access to essential documents, such as the Aadhaar card, take advantage of these, especially for covering unforeseen expenses.It's necessary to have a copy of your Aadhaar card as a KYC document while applying for funding options like personal loan.

What is an Aadhaar biometric?

Aadhaar biometrics refers to the unique physical and behavioural characteristics of an individual that are captured and stored in the Aadhaar database managed by the Unique Identification Authority of India (UIDAI). The purpose of collecting and storing biometric data in Aadhaar is to create a robust and secure identification system. Biometrics offers a more reliable means of verification compared to traditional identification methods such as documents and PINs. They are unique to each individual and difficult to forge, providing a higher level of security.

What are the methods of Aadhaar biometrics?

The Aadhaar system uses these biometric modalities to enhance the accuracy and reliability of identity verification, preventing duplication and fraud. The Aadhaar biometric primarily consists of two methods:

  1. Fingerprint data: Aadhaar captures the fingerprint patterns of all ten fingers during the enrolment process. This involves placing each finger on a biometric scanner to record the unique ridges and swirls. The fingerprint data is used for authentication purposes and is a key element in confirming the identity of an individual.
  2. Iris scan data: The Aadhaar enrolment process also includes capturing the iris scan of both eyes. This involves taking a high-resolution photograph of the iris, the coloured part of the eye. The iris scan is valuable for enhancing the accuracy of identification, especially in cases where fingerprint scans might be challenging due to factors like age, manual labour, or certain medical conditions.

How to update Aadhaar biometrics?

Updating Aadhaar biometrics is a straightforward process, but it is essential to note that online updates for Aadhaar biometrics are not available. Follow these steps to update the biometric details on your Aadhaar card:

  1. Visit a nearby Aadhaar enrolment centre: Initiate the biometric update process by visiting an Aadhaar Enrolment Centre in your vicinity.

  6. Update or record data: Upon successful verification, your biometric data will be updated or recorded in the UIDAI's database.
  7. Payment of nominal fee: Be aware that a nominal fee of Rs. 50 is required for the biometric update in Aadhaar. Ensure that payment is made at the centre.
  8. Data lock and update: The enrolment centre executive will securely lock and update your data in the UIDAI's database.
