The government has mandated submission of the 12-digit unique identity number by every bank account holder by March 31, 2018 to weed out unaccounted wealth.
For the same purpose, Aadhaar linking with income-tax permanent account number or PAN has also been made mandatory.
By March 31, all mobile SIM cards are also to be linked with Aadhaar to establish the identity of mobile phone users.
Out of the 109.9 crore banks accounts, almost 87 crore have been seeded with Aadhaar, said the official of the Unique Identification Authority of India (UIDAI), which issues the national ID number.
Of this, 58 crore have already been verified while in case of the rest the authentication process is underway with the documents that have been submitted to the banks, the official said.
The official further said that as against the 142.9 crore active mobile connections, 85.7 crore have already been linked with Aadhaar.
When contacted, UIDAI CEO Ajay Bhushan Pandey told PTI: "Yes, about 80 per cent of the bank accounts have been seeded with Aadhaar, and we hope that the remaining will be covered soon...Financial losses caused to banks and genuine account holders through identity frauds will be curbed."
Aadhaar is required as an identity proof of residents by various government and non-government entities.
While a five-judge Constitution bench is hearing a clutch of pleas challenging the constitutional validity of the Aadhaar programme, as things stand today, PAN, bank accounts, credit cards, insurance policies, mutual funds, pension plans and social welfare benefits will have to be linked to Aadhaarby March 31, 2018.
The UIDAI recently announced a new concept of Virtual ID which an Aadhaar-card holder can generate from its website and give for various purposes, including SIM verification, instead of sharing the actual 12-digit biometric ID.
The soon-to-be-introduced Virtual ID, a random 16-digit number, will give the users the option of not sharing their Aadhaar number at the time of authentication.
Aadhaar has also announced that it will soon include face recognition alongside iris or fingerprint scan as a means of verifying the users, helping those who face issues in biometric authentication or have worn-out fingerprints.
