It is an Account aggregator. Basically it will scan your Aadhar Card or Pan Card linked bank account and show the available balances of all the account number linked to the pan card.

It helps you in avoiding the hassle of login into every bank account and know your networth. Personally, I feel this is just another way of giving unnecessary data to the bank about your saving. Bank will surely suggest you some ULIP or FD plans after seeing how much excess fund you have in other account
