Credits were popular from long ago even during 1880s. Folks who purchased things from general stores usually have the proprietor of the shop write down amount owed to him by the folks. If these folks couldn't repay, the money firms such as Cart Collecting Co. would collect the owed debts from the debtors. Credit cards are small plastic card that contain the name and unique identification of the card holder which enables only the holder to purchase goods on credit. The card holder is billed periodically for the amount due.  The credit cards were first used in the U.S. in 1920. Such cards were first issued to customers by hotel chains and oil companies when purchases were made at their outlet.  Diner's Club Inc. was the first to introduce the universal credit card.  This was first issued in 1950. Credit card collectors also collect phone cards, credit tokens, or any similar collectibles that is used to replace money.
