A charge card is a type of payment card which allows its holder to make purchases on credit, with payment for purchases being charged to the account of the card issuer rather than to the cardholder.
At the end of each billing cycle – normally at the end of every month – the cardholder must settle the entire loan by repaying the card issuer in full.
Charge cards from American Express (issued by Swisscard AECS in Switzerland) are among the best known. In Switzerland, many credit cards are issued as charge cards, with the option to convert them to a genuine credit card by activating the "installment payment" option.
