  • Consensual: Nothing is shared with service provider by UIDAI without explicit consent (in the form of biometric or OTP) of Aadhaar holder.
  • Cost-Friendly: Reduced costs due to elimination of paperwork
  • Authorized: It is a legal process because UIDAI only shares information which has authenticated data.
