Linking Aadhar to Bank is a redundant exercise & bad software design

Today PAN & Aadhar are linked (31st Dec 2017 was the last date to link Pan with Aadhar) and this is already approved by the Supreme Court. Now Govt is trying to explain to the court why linking of Bank account to Aadhar is necessary. I am surprised that  Indian goverments IT experts have not realized that this is such REDUNDANT exercise because once government links Pan with Aadhar number, and since it is mandatory to provide PAN for a bank account the bank account automatically get linked to Aadhar ( as Bank account is already linked to PAN number). So there is no need for citizen to provide Aadhar details to the bank (by virtue of PAN-Aadhar data linkage) and Banks can STOP sending threatening mails to the customers!

Wish Finance Ministry & UIDAI would hire few experienced data architects & software engineers who could explain to the government 'how data association works' and stop the bank & government from wasting tax payers money in a redundant effort to link Aadhar to Bank account!


So bank has practically no need to ask customers to give their Aadhar number. Even for new bank customers  there is no need to provide Aadhar number because once they provide PAN number bank automatically comes to know if the person has linked the Aadhar with PAN and only then they would enable his new bank account.  It id critical that government does not go on distributing Aadhar access to 'private entities that çan acheive the purpose of authenticating a customer without knowing their Aadhar number and by just knowing their PAN number.


The following picture explains it. The Income Tax department has PAN-Aadhar linked for each PAN card holder. Bank account is already linked to PAN.  The way data association works if someone has not provided Aadhar to income tax department his PAN will automatically be deactivated and bank will be come to know about customers PAN deactivation.
                                                                        Obviously government has not thought about this because their IT experts have not educated them how data linkage works. I put the blame of this useless exercise on the IT experts who are being consulted by the government of India. Indian IT engineers from private sector are designing state of art software for fortune 100 companies and it is a pity that our government is not consulting these Indian IT experts.
