A Secured Credit Card is a Credit Card issued against a Fixed Deposit. You will need to create a Fixed Deposit of Rs 5,000 minimum in the app. Your credit card limit will be the same as your Fixed Deposit amount.
For example, if you create an FD of Rs 50,000, the Credit Card limit will be Rs 50,000. Your monthly bill will be generated upon usage which needs to be paid to reinstate the Credit Card limit. So, you enjoy a free credit period while your FD earns interest for you!
