For STATE BANK ANYWHERE users who are facing error. Do this:
Go to sbi app > mvisa > login > scan qr code
scan qr code, you will see an id/number, note it down
press cancel/back button, then select Type mVisa ID.
In that in mVisa merchant ID enter the number you noted down. Enter transaction amount. In Primary ID, enter your subscriber ID. Click on Pay Now. Done.
This is the first and best trick from me on this forum! Enjoy! Please give like if it works for you. Thanks.
