In 1950, the idea came from Frank McNamara, a businessman who’d forgotten his wallet while out to dinner in New York. The next day he invented a credit card called the “Dinners Club” which was a way to pay without having cash. This was the modern credit card, and first general-purpose charge card, however requiring a consumer to pay the statement balance in full each month. Then in the 1960’s Bank of America came out with a general-purpose credit card, which started the U.S on the credit use track.
