#10 Credit Card

Year: 1950

The concept of using a card for purchases was described in 1887 by Edward Bellamy in his utopian novel Looking Backward. Bellamy used the term credit card eleven times in this novel, although this referred to a card for spending a citizen's dividend rather than borrowing.

Then the concept of credit card was first used in the 1940s, in the United States, specifically to sell fuel to a growing number of automobile owners. In 1938 several companies started to accept each other's cards. Western Union had begun issuing charge cards to its frequent customers in 1921. Some charge cards were printed on paper card stock, but were easily counterfeited. In 1934, American Airlines and the Air Transport Association simplified the process even more with the advent of the Air Travel Card.

However the concept of customers paying different merchants using the same card was expanded in 1950 by Ralph Schneider and Frank McNamara, founders of Diners Club, to consolidate multiple cards. The Diners Club, which was created partially through a merger with Dine and Sign, produced the first "general purpose" charge card, and required the entire bill to be paid with each statement.
