D. Aadhaar Number Explanation: e-KYC is possible only for those who have Aadhaar numbers. While using e-KYC service, you have to authorise the Unique Identification Authority of India (UIDAI), by explicit consent, to release your identity/address through biometric authentication to the bank branches/business correspondent (BC). The UIDAI then transfers your data comprising name, age, gender, and photograph of the individual, electronically to the bank/BC.
