Hi.

According to NEET PG Rules 2021,

( https://nbe.edu.in/IB/Information%20Bulletin%20NEET-PG%202021%20-%20Final%20Version%20for%20website.pdf )

How to pay: The prescribed exam fee should be remitted through payment gateway provided using a Credit Card or a Debit Card issued by banks in India or other modes as may be made available and have been provided on the web page. Fee can not be deposited through any mode other than the payment gateway available while submitting online application form submission.

I hope this helps.

Good Luck
