How does writing all those details help? If someone wants to misuse the document, they still can. All they know to do is take a photocopy or scan the document that you submitted, Photoshop the same, removing the irrelevant stuff and leaving just your CTC attestation.
I didn't have to submit a hard copy. My bank asked only for the Aadhar number to be linked online. In fact, I linked mine, from home. And, I received a confirmation, through SMS, that my Aadhar had successfully been linked to my account.
When the government is going digital, why should a copy of the document be submitted to the bank? Most banks just need the number. My husband's Aadhar was linked to his account, in a jiffy. The bank didn't even ask to see the document.
If there is any discrepancy between the account holders details held with the bank and those mentioned in the Aadhar, the linking will not happen. The system turns it down.
