A prepaid credit card is not a credit card, since no credit is offered by the card issuer: the card-holder spends money which has been "stored" via a prior deposit by the card-holder or someone else, such as a parent or employer. However, it carries a credit-card brand (Visa, MasterCard, American Express or Discover) and can be used in similar ways just as though it were a regular credit card. A prepaid card or debit card can be approved with bad credit or no credit check.
