invention of credit card

In 1950, McNamara, a 35-year-old credit expert in Manhattan, invented the credit card.

But he believes this situation is entirely avoidable. So he organized a "diners club" according to his own idea. Participants can bring a dining charge card to record their consumption in the restaurant without having to pay cash. This is the earliest credit card.
