<h1>Mandatory biometric update for children enables Aadhaar authentication for benefits, scholarships and examinations.</h1> The UIDAI has implemented a mandatory biometric update (MBU) programme for school children aged 7-15, delivered through in-school camps and enrolment centres, with MBU made free for a limited period. Integration with UDISE+ enables identification of students due for updates and monitoring of MBU status. Initial enrolment below age five records demographic data only; fingerprints and iris biometrics are captured later via the MBU process once children reach the prescribed ages, enabling subsequent Aadhaar authentication for benefits, scholarships and examinations.
