credit card is part of a scheme of payments named after the small plastic card issued to users of the system. It is a card entitling its holder to buy goods and services based on the holder’s promise to pay for these goods and services.[1] The issuer of the card grants a line of credit to the purchaser (or the user) from which the user can use money for payment to a commercial or as a cash advance to the user. Usage of the term “credit card” to imply a credit card account is a metonym.
