Hello there, hope you are doing good!

I would like to tell you that to pay the fees for NIOS online, you will need to login as the student and from there you can pay through your credit card (Master or VISA) or you can pay through net banking. The link and details will be provided to you at the time of payment. I am attaching the official link to the NIOS website where you can login and find more information about the fees.

Hope you found this answer helpful.

Good luck for your future!
