When using the credit card again, the overpayments will be deducted first and then the credit limit.

2. Development History

Credit cards originated in the United States in 1915. The earliest institutions to issue credit cards were not banks, but department stores, restaurants, entertainment industries and gasoline companies. In order to attract customers, promote goods, and expand turnover, some stores and restaurants in the United States selectively issue credit chips similar to metal badges to customers within a certain range. Later, they evolved into cards made of plastic as customer purchases. As proof of consumption of goods, we have launched a credit sales service business for purchasing goods at our store or company or gasoline station with credit chips. Customers can purchase goods on credit at these stores and branches that issue chips and pay on schedule. This is the prototype of the credit card.

In the spring of 1950, McNamara and his friend Schneider invested US$10,000 to establish the "Diners Club" in New York, the predecessor of Diners Club. Diners Club provides members with a card that can prove their identity and payment ability. Members can use the card to record their purchases. This kind of credit card that does not require bank processing is still a commercial credit card.
