“Aadhaar Authentication” is a process by which the Aadhaar number along with demographic information (such as name, date of birth, gender etc) or biometric information (Fingerprint or Iris) of an individual is submitted to UIDAI’s Central Identities Data Repository (CIDR) for its verification and UIDAI verifies the correctness of the details submitted, or the lack thereof, on the basis of information available with it.

Face recognition is 1:N Match (one-to-many). UIDAI does 1:1 match (match against the stored biometric of the Aadhaar number holder).

UIDAI errors are displayed with an error code assigned for the causes leading to failure, one may contact to concerned entity with the error code to resolve.

i. Position yourself: Stand facing the camera or device, ensuring your entire face is clearly visible within the designated frame. Maintain a neutral expression with your eyes open and mouth closed and Stay still during the capture process to avoid blurry images.
ii. Focus and capture: The device or app will automatically attempt to focus on your face. Stay still and avoid sudden movements until the image is captured and follow specific instructions for capture, like blinking once or moving your head slightly. Look directly at the camera and maintain a neutral expression for successful capture.
iii. Lighting conditions: Stand in a well-lit environment with minimal shadows on your face and for successful capture good background with proper lighting conditions must be ensured.
iv. Remove any hats, glasses, or other coverings that might obscure your facial features.

Face authentication can be performed with any android mobile having the following specifications;
Android 9 and above
RAM: 4+ GB
Display Size: 5.5 Inches or greater
Camera resolution: 13 MP or greater
Disk space: 64 GB (Minimum 500MB free disk space)

Face authentication is a contactless method of authentication, which makes it more convenient than fingerprint or iris scanning.

This is always on enabled mode by default since individual gives the biometric including face at the time of capture.
