HDFC Infinia:
Based on the question, I believe you're going to open an FD to get the card as secured one, please keep in mind that if FD is closed your credit card might close as well and IMO just to get the card opening an FD isn't advisable unless you think that rewards from this card will outweigh your FD investment.
