HOW DO SECURED CREDIT CARDS work?

Secured credit cards DO NOT work that way. You have a set amount you have to give them, say $500. This will be your limit but instead of being able to just put the money back in when you use the card, you have to pay interest on your own money. then, you have to be prepared to pay annual fees and other nonsense charges on your own money. Oh, and you would have payments to them that you could probably be able to pay on line or mail to them. I dont think you can put more money in to raise how much you can spend on it either. Hope this helps.
