Gasoline Credit Cards
A user is
issued a credit card after an account has been
approved by the credit provider (often a general
bank, but sometimes a captive bank created to issue
a particular brand of credit card, such as Wells
Fargo or American Express Centurion Bank), with
which the user will be able to make purchases from
merchants accepting that credit card up to a
pre-established credit limit.
When a purchase is made, the credit card user agrees
to pay the card issuer. Originally the user would
indicate their consent to pay, by signing a receipt
with a record of the card details and indicating the
amount to be paid, but many merchants now accept
verbal authorizations via telephone and electronic
authorization using the Internet.
