subject: Why we use Prepaid Credit Cards [print this page] Unlike normal credit cards; a prepaid Mastercard, prepaid Visa card, or any other prepaid credit card have very low interest charges attached to it. Many banks do not even charge any interest on a prepaid credit card as you are using your own money that is deposited in the banks in advance. Usually, you are only required to pay a certain fee when you buy a credit card. Then, you have to pay charges for depositing or refilling money in your bank account. The benefits offered by a prepaid credit surpass the charges that are to be paid to maintain it.
