As far back as the late 1800s, goods were exchanged through the concept of credit, using credit coins & charge plates as currency. In 1949 Frank McNamara, had a business dinner in New York's Major's Cabin Grill realising he'd forgotten his wallet. He managed to find his way out of the pickle, but decided there should be an alternative to cash. McNamara and his partner, Ralph Schneider, returned to Major's Cabin Grill in February of 1950 and paid the bill with a small, cardboard card. Coined the Diners, it claims the title of the first credit card in widespread use.
