Process is same everywhere and with every financial app. VKYC is necessary if you are making FD with term more than 365 days. Upto 365 days, only Aadhaar and PAN based KYC is enough. On maturity funds are credited to the account whose Netbanking or UPI was used to fund the FD. DC/CC not allowed for FD creation. Also other people account can't be used to fund. The name you are entering for FD should match with netbanking account or UPI else it won't take funds. So own acc. funding is allowed only.Has anyone booked an FD via the app? Is there a VKYC done for making an FD and what documents do they ask?
If you want to invest for longer term i.e more than 365 days, you need VKYC differently for every bank. I suggest you to better visit bank if it is near you and invest directly with them. Opening savings and giving them FD will bring more for you. Investing thru Financial App is just a medium. The bank that is having FD do all the stuff just like you visit them i.e a Permanent Cust ID will be created with them that will be mapped to PAN and any savings/fd you open with them in future will remain with same Cust ID in future.
