• The concept of a multiple-establishment credit card came in the mind of Frank X. McNamara in 1949, when he had forgotten his wallet and was unable to pay for his dinner at a fancy restaurant, where he was dining with his relatives.
• Store-specific credit accounts were used at that time, but a single credit card capable of handling all merchant establishments, and involving a middleman company, was never thought of before.

McNamara founded The Diners Club, the first credit card company, in 1950.

The initial card offered by Diners Club didn’t involve revolving credit, and the dues were to be paid off in full by the end of the month. The credit cards that we see now came much later.

Initially targeted at salespeople, the company started charging a $3 annual fee and also charged the establishments 7 per cent for each transaction. The paper-based cards showed tremendous growth in a year, with 20,000 people using it.
