Bad credit credit cards come with a few benefits, of which the most important is that it allows you to improve your credit score. The best way to do this is to make your payments on time. Another way is to ensure that you set limits on the amount of money you spend in a month on the credit card. A secure credit card sets a limit which can help control your spending. Make it a habit of purchasing within a budget. This will help you maintain a good credit score once you re-establish it.
