For the safety and security of Aadhaar Cardholders, UIDAI has also shared an important note on its official website that "Under the PML Rules Aadhaar is one of the officially valid documents accepted for opening bank account and the bank is required to do other due diligence for banking transaction or KYC. If at all some fraudster tries to open bank account using Aadhaar and bank doesn't carry any due diligence then in such case an Aadhaar holder cannot be held responsible for bank's fault. It is just like if some fraudster opens a bank account by presenting someone else's Voter card/Ration card, it is the bank that would be held responsible not the voter or ration card holder. Till date no Aadhaar holder has suffered any financial loss on account of such misuse."
