Yes, I had FD based PNB RuPay Select credit card. They will process immediately, and there is no documents required.
You will get the virtual card in 12 hours, once activated, you can use that card in UPI as well, works well.
Rewards are there for UPI payments also.
There is no joining and annual fee.
and some of charges also less.
but limitation is 80% of your FD amount.
you can't convert this card to non FD card. you have to close and apply for new card.
