If you receive a reminder from UIDAI, do not ignore it. Completing the Mandatory Biometric Update on time helps avoid future authentication problems and keeps your child’s Aadhaar information up to date.
Common Biometric Update Problems in Children
Most biometric updates are completed without any difficulty. However, some children may face minor issues during the process.
These problems are usually temporary and can often be resolved by trying the scan again.
1. Fingerprints Are Not Captured Properly
This is one of the most common issues, especially for younger children.
Possible reasons
- Child keeps moving.
- Fingers are dirty or wet.
- Finger is not placed correctly on the scanner.
- Scanner needs cleaning.
Solution
- Clean and dry the child’s hands.
- Ask the child to stay still.
- Let the operator capture the fingerprints again.
- If the scanner appears faulty, request another device if available.
2. Iris Scan Fails
The iris scanner needs the child to look directly at the camera for a few seconds.
Why it happens
- Child closes their eyes.
- Child looks away.
- Bright reflections interfere with the scan.
- Child is scared.
Solution
- Comfort the child before the scan.
- Ask them to look at the light or camera.
- Remove reflective glasses if instructed by the operator.
- Try the scan again.

3. Photograph Is Blurred
A blurred photograph may not meet quality requirements.
Solution
- Ask the child to sit still.
- Make sure the face is clearly visible.
- Retake the photograph if needed.
Why Can a Mandatory Biometric Update Be Rejected?
Although uncommon, a biometric update request may sometimes be rejected after submission.
Possible reasons include:
- Poor biometric quality.
- Incomplete biometric capture.
- Technical errors during processing.
- Incorrect information entered during the update.
- Biometric data did not meet UIDAI quality standards.
If your update is rejected, do not panic. A fresh biometric update can usually be submitted.
How to Check the Biometric Update Status
After completing the update, you will receive an Update Request Number (URN) or acknowledgement slip.
You can use this reference to check the status of the update through the official UIDAI status-checking service.
Keep the acknowledgement slip safe until the update is successfully completed.
How Long Does It Take for the Update to Be Completed?
The biometric capture itself usually takes only a few minutes.
However, the update request must be processed by UIDAI.
The processing time can vary depending on verification and system workload.
Do not worry if the status does not change immediately after your visit.
What Happens After the Biometric Update Is Approved?
Once the update is processed successfully:
- The child’s Aadhaar record is updated.
- New biometric information becomes part of the Aadhaar database.
- Future biometric authentication becomes more reliable.
What If Aadhaar Authentication Still Fails?
Sometimes parents complete the biometric update, but authentication problems continue.
Possible reasons include:
- The update is still being processed.
- The authentication device has a problem.
- The service provider is experiencing technical issues.
- Incorrect Aadhaar number is being used.
What should you do?
- Wait until the update is fully processed.
- Try the authentication again later.
- Use another biometric device if available.
- Contact the organisation requesting Aadhaar authentication if the issue continues.
Common Mistakes Parents Should Avoid
Many biometric update delays happen because of small mistakes.
Avoid these common errors.
Waiting Too Long
Do not ignore the Mandatory Biometric Update after your child reaches the applicable age.
Not Carrying the Aadhaar Number
Always carry the child’s Aadhaar details or Aadhaar letter/card.
Leaving Without Checking the Acknowledgement Slip
Always collect and keep the acknowledgement slip safely.
Not Verifying the Details
Before leaving the Aadhaar centre, check that the child’s details shown on the screen are correct.

- Dress the child comfortably.
- Clean the child’s hands before fingerprint scanning.
- Make sure the child is well-rested.

Frequently Asked Questions
What is the Mandatory Biometric Update (MBU)?
It is the process of updating a child’s fingerprints, iris scan, and photograph at the prescribed ages to keep Aadhaar records accurate.
Is the update compulsory at age 15?
Yes. UIDAI requires another biometric update around the age of 15 because biometric features mature as children grow.
Can the update be completed online?
No. The child must visit an authorised Aadhaar Seva Kendra or Enrollment Centre because biometric information must be captured in person.
What happens if I miss the update?
Delaying the update may lead to biometric authentication issues and continued reminders from UIDAI. It is best to complete the update as soon as possible.
Can I visit any Aadhaar Seva Kendra?
Yes. You can generally visit an authorised Aadhaar Seva Kendra or Enrollment Centre that provides biometric update services.
What should I do if my child’s fingerprints cannot be captured?
Stay calm and allow the operator to try again. Cleaning the child’s hands and ensuring they remain still often improves the capture.
Is an appointment compulsory?
Some centres accept walk-in visitors, while others may offer appointments. Check with the centre before your visit if you want to avoid waiting.
Can the acknowledgement slip be lost?
It is strongly recommended to keep the acknowledgement slip safely until the update is completed because it contains the reference needed to track the request.
