No one will know that it is not a traditional charge card. A prepaid card is loaded with funds either online or at the retailer of your choice that offers the service. There is usually a fee when loading funds onto your account. This fee varies so you should choose a card according to the cost associated with its services. There are no interest charges, no over limit fees and usually no membership fees. With a prepaid card, you pay to load funds or a minimal monthly access fee. A bit of research on your part can find you the best deal.
