What is FD Credit Card?

I am trying to figure out what is credit card against fixed deposit?

FD credit card or credit card against fixed deposit is a credit card that is issued to you against your fixed deposit. So you can safely say that this is a secured credit card which is issued to you after keeping your fixed deposit as a collateral.
The best part about a fixed deposit credit card is that you get an easy approval. If your credit score is on a lower side, you will still get a credit card. This will also give you an opportunity to improve your creditworthiness.
All this happens while your fixed deposit earns interest and you use the credit card. Isn’t that something?
