These are cards that use a fixed deposit you create with the bank as collateral
A credit card can be used to improve one’s credit score. Paying your card bills in full and on time can help you improve your score. However, not everyone will be eligible for a credit card, especially those who have never taken credit before or those with poor credit history. In such cases, banks offer secured cards, which can be used to establish, or even re-establish one’s credit footprint.
