The Green Dot Credit Card is a pretty good prepaid credit card. A prepaid credit card is one that you deposit money into your account and you can spend that money by using your card. You can also withdraw your money anytime at an ATM.
What makes the Green Dot card so good is it doesn't have many fees. Most prepaid cards have a lot of fees but Green Dot doesn't have as many and they aren't as expensive. If you can get a regular credit card I would recommend that, but if you have to use a prepaid card I recommend getting the Green Dot over other ones.
