Aadhaar seeding is a process by which UIDs of residents are included in the service delivery
database of service providers for enabling Aadhaar based authentication during service
delivery, linking of UID to beneficiary ID.
As an example, MNREGA will require authentication before payout therefore in such a
scenario, it will be essential to map UID of the resident with MNREGA Job Card number and
other demographic information. Similarly, banks and insurance carriers may want to map
Aadhaar numbers of all their customers. The objective is not to replace the currently used
unique identifier of the customers/ residents/ beneficiaries with Aadhaar but the objective is
to seamlessly enable Aadhaar authentication without impacting any other interface that the
service providers maintain with their customers.
Aadhaar enrolment involves collection of basic demographic details (called Know Your
Resident (KYR) data) along with biometrics and photograph and generation of EID
(Enrollment ID) which is a transaction reference number. After due processing, UIDAI
generated UID numbers for enrollments that are accepted (based on de-duplication and
quality). The KYR data and photo along with EID and UID numbers are published by UIDAI
back to the registrars as EID-UID XML files.
