The cardholder is turn promises to the card issuer (usually a bank or a credit union)
to pay the borrowed amount and other agreed charges. Credit cards differ by
credit card provider (for instance, Visa, American Express, MasterCard),
credit card type (silver, gold, platinum), charged interest and annual costs.
