The stamps and registration department may make Aadhaar authentication “A MUST FOR PROPERTY REGISTRATION” in Karnataka.  However, this authentication can happen only in case of customers who are Aadhaar holders.

The services will be offered by Centre for e-Governance, Karnataka, which is in charge of the enrolment process. This will be done in coordination with custodian of the data, Central Identities Data Repository. Since Aadhaar authentication works on biometrics (including thumb impression), a mandatory process during the time of registration (only thumb impression), its validation will show up discrepancy and impersonation, hence eliminate dubious transactions.
Any registration, be it a document or marriage, involves recording the biometrics of the executer along with their signature and photograph.

During the process the process of property registration thumb impression and the photo of all the sellers and the buyers are captured and with the AADHAAR authentication, the captured thumb impression and the photo of the buyer or seller is matched with that in the back-end server, but for this process to be successful the buyers and sellers has to be registered on Aadhaar. Since all biometrics are synced the data of the person will pop up from which the previous transactions, if any, can be ascertained and the identity of the person found. This way, a discrepancy/defect/fraud/multiple sales of the same property can be spotted and the transaction stopped.
This linking of Aadhaar with the stamps and registration department will detect impersonation in property transactions and curb fraud and dubious registrations. Once Aadhaar is made mandatory, the 12-digit unique identification number will have to be mentioned in all government and bank transactions. The government has mandated Aadhaar as a document for proof of identity (PoI) and proof of address (PoA). Since the UID number cannot be tampered with, it can bring down property-related scams to a great extent.
