Prepaid credit cards are great for those who find it difficult to control their spending habits. They have a limit imposed by the cardholder that is solely determined by how much money they load onto it. If the person does not have money to load onto the card, then they wont be able to use the card. In short, by the time a prepaid card is used, the bill is already paid. Its probably the best type of credit card available for people who want to stay out of debt.
